Click here to see him as a monster 
Played by: Song Kang

The main protagonist of the comic, a Hikikomori who moved into an apartment building just before monsters appeared.


  • And Then John Was a Zombie: Hyun begins to resist his monster infection less and less, for the sake of having the strength to protect everyone else. In the climax of the webtoon, he finally gives into his monster infection and turns to defeat the Final Boss. Although the same thing happens in the miniseries, Mr. Han gives him a Cooldown Hug that turns Hyun back into a human, albeit at the cost of the inventor's life.
  • Better to Die than Be Killed: In the earlier chapters, Hyun keeps thinking about ending it all so he can at least die a human. He's forced into heroism before he can do so and later decides that he wants to live after all.
  • Big Brother Instinct: Towards Sook and Yeong. He had a younger sister, but she tragically died in a car accident alongside their parents.
  • Blade on a Stick: Hyun's main weapon is a broken mop handle with a knife attached to it. Upon meeting Mr. Han, it gets upgraded into a spear that can conduct electricity. In the webtoon, it eventually becomes a part of his monster form.
  • Broken Ace: Flashbacks show that he was a very popular and skillful student, until something happened...
  • Bullying a Dragon:
    • After all the abuse Hyun suffered at the hands of his former friends and realizing that his family never truly cared about his wellbeing, he adopts a fairly jaded and suicidal personality. However, upon seeing his bully attempting to bait another student into committing suicide, he finally snaps and almost successfully kills his bully by pushing him into the road instead.
    • In the miniseries, Ui-myeong shoots Yu-ri and Sang-wook and ridicules Hyun for crying after killing whom he thought was Sun-young. He also opens fire on the Green Home residents, most of whom Hyun had come to regard as his friends. As expected, he changes into his monster form not soon after.
  • Character Development: Undergoes this throughout the story, turning from a cynical jerk who only wants to commit suicide to a heroic individual that wants to save as many people as possible.
  • Dare to Be Badass: Initially, Hyun is a depressed teenager who only wants to kill himself as soon as possible. However, when Mr. Han asks him if he wants to save Sook-yeong and Yeong-sook, Hyun immediately says yes.
  • Dangerous Forbidden Technique: Any time Hyun uses his monster powers, he risks changing into a monster permanently and giving control over to his monster side.
  • Dark and Troubled Past: Hyun was a dedicated and well-rounded student and a great dude in general...until his classmates and peers started to bully and socially exclude him for pretty much no reason. To make matters worse, his parents betrayed his trust and did little to intervene because the kid who started it all was the son of Hyun's father boss. Hyun's life spiraled out of control from there, causing him to become anti-social, bitter and mentally unstable.
  • Death Seeker: At first, he planned on committing suicide after seeing a movie (or attending a gaming event in the miniseries) he had been waiting for, feeling he had no reason to live after the death of his family. His character development changes him into someone who desperately wants to survive the apocalypse and live.
  • Earn Your Happy Ending: After dealing with so much trauma throughout much of his late adolescence (from dealing with his bully to losing his parents and younger sister in an accident to fighting monsters and becoming one himself), Hyun is able to find the right people whom he calls his family: the surviving residents of Green Home Apartment.
  • Friend to All Children: What kickstarts Hyun's character development is his determination to rescue Sook and Yeong after their father dies, to the point that he is willing to cross multiple monster-infested floors just to get them to safety.
  • Healing Factor: As a result of being infected, Hyun has a rapid healing factor that enables him to get up close and personal with the other monsters.
  • Heroic Willpower: So far, Hyun is the only person able to fight off his impending monsterization with sheer willpower alone.
  • Hikikomori: Has become one long before the story began. He grows out of it by force when the monsters appear.
  • Important Haircut: In Episode 8. After a pep talk from Eun-yu, he finally decides to let go of his past and starts being more sure of himself.
  • Jerkass: At the start of the story, he was more depressed about his inheritance being so small than the fact that his entire family died. He grows out of this when the monsters start appearing.
  • Jerkass Has a Point: While his antagonistic attitude towards his family is pretty awful in the prologue-especially since his mom was trying to be nice-it's at least partially understandable, given that his parents did next to nothing to help him when he was being bullied.
  • Jerk with a Heart of Gold: Even at his worst, Hyun still had the potential to be good person.
  • The Main Characters Do Everything: Justified, as Hyun is the only main character that has some control over his monsterization, he's much stronger than everyone else, and is thus forced to be the muscle of the group.
  • Mercy Kill Arrangement: Early on in the miniseries, he asks Ji-su to kill him before he can turn and hurt anybody.
  • Naked on Arrival: In the final chapter, Hyun came out of his cocoon as a naked, evolved, and humanoid monster.
  • Nice Guy: Flashbacks showed that he used to be this but something happened that made him a hikikomori. Apparently, a bully who was the son of his father's boss betrayed his trust, beat him to an inch of his life, and turned Hyun's friends against him. His family's lack of support only worsened things, to the point that Hyun thought suicide was the only option left for him.
  • Post-Final Boss: Hyun forfeits his humanity and manifests his full monster form to defeat monster Joon Shin. But this causes his Superpowered Evil Side to take him over to good, forcing Hyuk to sacrifice himself to allow Jisu and Wook to escape.
  • Pretty Boy: Is repeatedly called one in the miniseries by multiple characters.
  • One-Winged Angel: During a solar eclipse in the miniseries, Hyun-su's monsterization literally transforms one of his arms into a set of serrated wings that he uses to kill Ui-myung's host. Mr. Han manages to prevent him from harming the rest of the survivors ... but at the cost of his own life.
  • Power at a Price: The more Hyun uses his powers, the more likely he'll become a monster. In chapter 138, he finally gives into his monsterization for the power to kill Joon Shin and protect his friends.
  • Ship Tease: With Ji-su in the webtoon and Eun-yu in the miniseries.
  • Shock and Awe: Uses an electric spear, to the point that it's part of his monster form in the webtoon.
  • Shrinking Violet: At the start of the story, Hyun has a tendency to hunch in on himself, speaks quietly enough that he is often asked to repeat what he just said, and avoids eye contact with people.
  • Sole Survivor: His entire family died in a car accident when their car crashed into a truck.
  • Spoiled Brat / Used to Be a Sweet Kid: Earlier on in the story, he is presented as a greedy, self-absorbed, and disrespectful brat. At his own family's funeral, he lashes out in front of everyone present and angrily asks how he is meant to live off of the meager savings they have left behind. Deconstructed later on with The Reveal that although Hyun was being bullied and beaten regularly by the son of his father's boss, his family simply turned a blind eye for fear of Hyun's father losing his job if they spoke up. When Hyun finally fights back by pushing his bully into oncoming traffic, his father is fired and Hyun is isolated further in school. At one point, he also overhears his parents and little sister blaming him for his own abuse and outright calling him a burden. In short, Hyun only became a brat when he realized that no one really loved him and his efforts at standing up for himself were futile.
  • Superpowered Evil Side: All the infected have this, but Hyun's is very eager to play mind games with him.
  • Super Strength: The more his infection progresses, the stronger he gets. By the end, he can break the floor by casually jumping and throw his spear with enough force to punch a hole in a wall.
  • Supporting Protagonist: Both the webcomic and the miniseries occasionally take a backseat from Hyun's story to focus more on what the other survivors are up to.
  • Tender Tears: Hyun cries multiple times in the miniseries, but most notably during his attempted suicide, when he is unable to stop Jae-heon from being killed, and after seeing Mr. Han's dead body.
  • Trauma-Induced Amnesia: In the miniseries, the shock of transforming into a monster before turning back into a human is too much for him and he loses most of his memories. Despite this, he tears up at the sight of Mr. Han's corpse and even says that his heart feels like it's breaking.

    Yoon Ji-soo/Ji-su 
https://static.tvtropes.org/pmwiki/pub/images/jisu.jpg
Played by: Park Gyu-young

A bass player who lived in the apartment directly above Hyun's.


  • Adaptation Dye-Job: In the webtoon, Ji-su has bright brown hair. In the mini-series, her hair is black, but the lower half is dyed pink, befitting her "rocker" personality.
  • Anger Born of Worry: As part of their Ship Tease, she is shown worrying for Jae-heon, only to snap at him for provoking The Beefcake when he reveals himself to be alive.
  • Batter Up!: Ji-su has a metal bat as her weapon of choice. It later gets spikes after Du-sik fixes it up.
  • Cartwright Curse: The source of her angst in Episode 9, considering how her ex-boyfriend committed suicide and Jae-heon dies after professing his love for her.
  • Celebrity Resemblance: Ji-su is stated by both Hyuk and Hyun to resemble Maria from the in-universe cartoon Maria from the Sky. Hyuk even states her personality is similar to Maria's.
  • Determinator: No matter the situation, Ji-su absolutely refuses to give up. Even if she's going to die tomorrow, she'll still fight to survive today.
  • Hidden Heart of Gold: Ji-su pretends to be more cold-hearted than she is to survive, but she's far too kind to actually do anything brutal.
  • Inelegant Blubbering: When she sees Jae-heon's grave, Ji-su is reduced to crying and screaming as she remembers the last time she ever saw him.
  • Love Hurts: Ji-su's boyfriend committed suicide and Hyun turns into a monster in front of her to save her life in the last few chapters. As for the miniseries, let's not forget Jae-heon, who confesses that he wants to be with her ... only to die right after while protecting the other residents.
  • Mercy Kill Arrangement: In the miniseries, Ji-su agrees to kill Hyun if ever he turns, only if he does the same for her. She almost goes through with it in Episode 10, only to be stopped by Eun-yu.
  • Morality Chain: Ji-su is able to calm Hyun down, preventing his monster side from taking over.
  • Nice Girl: She's one of the nobler survivors, completely willing to risk her neck for people she's just met. In the miniseries, she's constantly looking out for the little kids and hands Jin-ok a protein bar she'd been saving for herself when the older woman is too depressed over her daughter's death to eat.
  • Nice Job Breaking It, Hero:
    • In the webtoon, by dousing Myeong-Ja's infected cocoon with gasoline, she allowed Yi-hyun's violent personality to set it on fire, which inadvertently enraged every single monster in the area surrounding the building.
    • Early on in the miniseries, she and Jae-heon create a massive SOS banner, which they then hang from the rooftop. Come Episode 8, Yi-kyung orders Sang-wook and Hyun to take it down for fear of attracting the military's attention. This leads to Hyun being unable to warn the survivors in time of the infected security guard's existence, which results in Jae-heon's death.
  • Red Oni, Blue Oni: She's the fiery, impulsive, and action-oriented red to Jaeheon's calmer and quieter blue.
  • Ruptured Appendix: Happens to her in the miniseries. When the plan to get proper medical supplies for her goes south, Ji-su has to undergo emergency surgery from Eun-hyuk without any anaesthesia. To make matters worse, although Eun-hyuk is a medical student, he's also one who has never done surgery before.
  • Ship Tease: She and Jae-heon have their moments in the miniseries.
  • Suicide Is Shameful: Ji-su hates the idea of suicide after her ex-boyfriend hung himself. Thus, she'll do everything to survive and refuses to let anyone kill themselves as well.
  • Tragic Keepsake:
    • Her bass is her boyfriend's. He left it to her after committing suicide.
    • In the miniseries, Eun-yu gives her the broken shard of Jae-heon's katana after his death and it becomes her main weapon from then on.
  • Traumatic Haircut: Her hair becomes shoulder-length in the miniseries after a monster grabs on to her hair in the car park and Jae-heon has no choice but to slice it off.
  • Unstoppable Rage: As the webtoon goes on, she becomes more and more protective of Hyun and loses her temper if he's threatened.
  • Vitriolic Best Buds: With Eun-yu in the miniseries. The 'best buds' part may be a bit of a stretch, considering how acidic their behavior towards each other can get, but when Jae-heon dies, Eun-yu is the only person shown actually comforting her, first with chocolate, then with somewhat kind words.

    Han Du-sik/Du-sik 
https://static.tvtropes.org/pmwiki/pub/images/dusik.png
Played by: Kim Sang-ho

The sole occupant of Room 1408. He has limited mobility due to having lost part of a leg (or having lost feeling in both legs in the miniseries), but is pretty good at weaponry crafting.


  • Better to Die than Be Killed: He tells Hyun that the last bullet in his gun is reserved for him, seeing as he doesn't want to die of old age, be killed by the monsters, or turn into one. In the mini-series, he ends up using it on the Spider Monster after it almost eats Sook-yeong.
  • Cool-Down Hug: Administers one to Hyun-su in the miniseries after his monsterization worsens during an eclipse.
  • Cool Uncle: Acts as this towards Sook-yeong and Yeong-sook.
  • Died in Your Arms Tonight: In the webtoon, Du-sik dies in Hyun's arms after his flame bomb clears the garage of monsters. The miniseries inverts this a bit by having him hold Hyun to prevent him from hurting the other residents and gets impaled by the latter's One-Winged Angel form in the process.
  • The Engineer: He's in charge of making all the weapons and technology the group uses. He reveals his skill is the result of too much time on his hands.
  • Establishing Character Moment: Saving Hyun from the Eyeball Monster and asking him to rescue Sook-yeong and Yeong-sook from their apartment.
  • Foil: To Hyun. Both were people who "lost" their loved ones ( Dusik having being abandonned by his wife with their son, Hyun's family dying in a car crash), both were something of geeks(however the generational gap stops them from fanboying over the same stuff), and both were infected. However Dusik is consistently a great fellow, while Hyun was an complete asshat before he started mellowing out again. Dusik was physically disabled, while Hyun was not. Dusik was also much Older and Wiser than Hyun.
  • Handicapped Badass: Du-sik might be wheelchair-bound, but his skill in weapon crafting is top-notch enough that Eun-hyuk gives the go-ahead for Hyun to retrieve him from his apartment—a mission that involves going through fourteen monster-infested floors.
  • Heroic Sacrifice: In both the webtoon and the miniseries, albeit in different ways. In the webtoon, after realizing his monsterization gave him a leg, he throws a huge flame bomb to kill all the monsters attempting to enter from the garage at the cost of his life. In the show, he dies by giving Hyun-su a Cooldown Hug while the latter is in a fully berserk monster mode.
  • MacGyvering: He manages to create a homemade rifle out of a hollowed-out crutch and an air compressor. He also creates/modifies weapons for several others, including a spiked/bladed bat, a riot shield, and an electrified spear.
  • Nice Guy: Despite food being scarce, Du-sik is more than happy to share it with the survivors.
  • No Good Deed Goes Unpunished: The webtoon reveals that in the past, he saved a child's life at the cost of his foot, which resulted in his wife and child leaving him because he couldn't find work.
  • Throwing Off the Disability: Seeing as monsterization gives a human what they most desire, Du-sik regains the use of his legs in both adaptations. In the webtoon, he is able to regrow one of his legs. In the latter, he is able to walk again and manages to keep Hyun-su from going on a wild rampage.

    Jung Jae-heon/Jay-hun 
https://static.tvtropes.org/pmwiki/pub/images/jaeheon.png
Played by: Kim Nam-hee

A Korean teacher and devout Christian who has lived at Green Home for over a year.


  • Amazon Chaser: According to Jae-heon's actor, he started to have feelings for Ji-su when she charged The Beefcake first and gave it a Groin Attack to boot.
  • Anguished Declaration of Love: Unsure of whether or not he will survive a battle in the miniseries, he confesses to Ji-su and tells her he wants to be with her.
  • An Arm and a Leg: The monsterized Mr. Kim slices off his left arm in the miniseries.
  • Badass Preacher: While not a pastor per se, he is a devout Christian who isn't afraid to share his faith with others and kills the most monsters out of the main characters.
  • Beware the Nice Ones: He looks like a harmless, slightly geeky, teetotaling proselytizer, but is quite prolific with a sword. In the webtoon he was also a kumdo expert, explaining his proficiency with weapons.
  • Heroic Sacrifice: In the miniseries, he holds off the monsterized Mr. Kim in the elevator while bleeding out from a missing arm and orders Eun-hyuk to throw a Molotov cocktail and burn the both of them.
  • Katanas Are Just Better: He has a katana as his weapon.
  • Nice Guy: In his first appearance, he explains Myeong-sook's behavior to an understandably creeped-out Ji-su and even apologizes for being too forward. In the webtoon, he doesn't shun Hyun for being infected—a trait that carries over into the miniseries. It's also implied that he was the one who told the other residents why Sang-wook has such a big vendetta against Choi Yoon-jae. He's also a devout Christian but very tolerant of other people's beliefs. When he dies, all of the survivors present are in tears, including Eun-hyuk.
  • Odd Friendship: With Sang-wook in the miniseries. After Jae-heon prevents a heavily injured Sang-wook from leaving the compound, the gangster warms up to him considerably and even punches Seung-wan in the face after the latter shoves an injured Jae-heon into a display case. At the start of Episode 9, Sang-wook is shown mourning his death and even pours soju all over Jae-heon's grave as a way of paying his final respects.
  • Recovered Alcoholic: In the miniseries.
  • Red Oni, Blue Oni: He's the calmer, more level-headed blue to Ji-su's fiery and emotional red.
  • Religious Bruiser: Prior to each fight, he yells out verses and prays for strength. In one of his conversations with Sang-wook in the miniseries, he reveals that religion helped him overcome his alcoholism.
  • Sacrificial Lion: He is the first sympathetic character killed by the monsters to show that Anyone Can Die.

    Kim Sook-yeong/Sook and Kim Yeong-sook/Yeong 
https://static.tvtropes.org/pmwiki/pub/images/kids_9.jpg
Played by: Heo Yool (Sook-yeong), Choi Go (Yeong-sook)

Two children living in an apartment below Dusik's. Sook is 9 and Yeong is 6.


    Lim Myeong-ja/Lim Myeong-sook 
https://static.tvtropes.org/pmwiki/pub/images/myeong.jpg
Played by: Lee Bong-ryun

A middle-aged woman who also appears to be infected by the virus. Not the most sane, given her past...


  • Adaptational Name Change: Her name is Myeong-Suk in the miniseries.
  • Deader than Dead: In the webtoon, her monster form eventually becomes a cocoon, only to get incinerated by Yi-hyun, therefore discarding any chance of her evolving. Although Ui-myeong leaves her alone in the miniseries, the building itself collapsed after being shot at by the military, leaving her fate unknown.
  • Fingore: In the miniseries, she almost succumbs to monsterization while cooking dinner and ends up chopping off her fingers as a result.
  • Hidden Depths: She's actually fully aware that her "baby" is a hallucination and she's pushing around an empty stroller, but she keeps up the façade as she would rather live in a hallucination than accept the truth.
  • Living MacGuffin: Yi-hyun burns her cocoon after Ji-su soaked it in gasoline in a failed attempt to destroy it, which was enough to aggravate all the surrounding monsters and kick-start the climax.
  • Mama Bear: Due to losing her baby, she's very protective of all children, especially Sook-yeong and Yeong-sook.
  • Mercy Kill Arrangement: In the miniseries, she asks Mr. Han to kill her if she turns. However, since her monster form is ultimately a peaceful one, he cannot bring himself to do it and is even seen talking to her as he awaits his own transformation.
  • Outliving One's Offspring: Prior to the start of the series, her baby died when the stroller rolled out into the middle of the street.

    Ahn Gil-seop/Seop 
https://static.tvtropes.org/pmwiki/pub/images/gilseop.png
Played by: Kim Kap-soo

An old man who decides to venture out with his caregiver Yu-ri instead of staying put and dying in his room.


  • Big Damn Heroes: Twice. He saves the main characters from being killed in the car park with an improvised flamethrower. Later on, he draws The Beefcake's attention away from a badly-dazed Hyun by throwing Molotov Cocktails at it and pushes Hyun out of the way when the monster attempts to crush them both.
  • Blood from the Mouth: Happens to him in the miniseries whenhe is about to let himself be crushed by The Beefcake.
  • Cool Old Guy: After emerging from his unit, he's not afraid of putting his life on the line to help others, and he's pretty well-prepared at defending himself with his crossbow. He helps Hyun and Sang-wook when they're in a pickle to defeat the Tentacles Monster (webtoon)/the Long-Armed Monster (miniseries). In the miniseries, he also becomes a grandfather figure to Sook-yeong and Yeong-sook, has a motorcycle lying outside that he occasionally peeps at in hopes of being able to ride it soon, and burns down some monsters in the carpark with a flamethrower.
  • Do Not Go Gentle: Even though he's terminally ill, he wishes to kill as many monsters as possible before that happens.
  • Heroic Sacrifice: He pushes Hyun out of the way of The Beefcake’s punches and gets crushed in his place. Subverted in the miniseries where Yi-kyung suddenly returns with a firetruck to mow down the sucker down.
  • Nice Guy: Although she shows shades of being The Gadfly early on towards Hyun and Yu-ri, he's definitely one of the nicest characters in the series and it shows.
    • He eats dinner with Hyun and Sang-wook when the rest of the survivors shun them, and tells them about himself to make the pair loosen up.
    • He sternly, yet kindly reprimands Seung-wan when the younger man understandably panics and reminds him to take good care of himself.
    • The main reason he wanted to leave his apartment in the first place? He believes that Yu-ri deserves more than taking care of him until he passes.
  • Old Soldier: It's implied that he is a retired soldier and is completely unafraid of dying if it means saving everyone else.
  • Passed in Their Sleep: How he dies in the miniseries. Sook-yeong goes to wake him for breakfast and finds that she can't. While it's a sad moment for all the survivors, his death here is definitely more peaceful than how he goes out in the webtoon.

    Park Yu-ri/Yuri 
https://static.tvtropes.org/pmwiki/pub/images/yuri_60.png
Played by: Go Yoon-jung

The senior caregiver for Mr. Ahn. She helps to patch up the survivors and suffers from asthma.


  • Beware the Nice Ones: In the miniseries, mild-mannered Yu-ri is ultimately the one who kills the rapist when he starts beating up Ji-su.
  • Death by Adaptation: Dies alongside Sang-wook in the miniseries from gunshot wounds before they could drive off to find more asthma medication for her.
  • Heroic BSoD: After stabbing Kap-soo in the miniseries, the poor girl can only mumble "I killed a person" when Sang-wook finds her. As the pair lie dying from their gunshot wounds, she repeats the statement and voices her fear that it'll be the last thought she has before passing.
  • Holding Hands: Right before he dies, Sang-wook takes her hand so neither of them are alone in their final moments, and only then does she close her eyes for good.
  • The Medic: Helps tend to the survivors' wounds, due to her past medical knowledge.
  • Official Couple: With Sang-wook in the webtoon,and teased in the miniseries.

Lower Floor Group

    Lee Eun-yu/Eun 
https://static.tvtropes.org/pmwiki/pub/images/eun_4.png
Played by: Go Min-si

A spirited teenager and Eun-hyuk's younger sister.


  • Aerosol Flamethrower: Begins using this as her weapon towards the end of the webtoon.
  • Adaptational Jerkass: Likes to sass at her fellow survivors in the miniseries.
  • Bratty Teenage Daughter: Although she isn't as angsty as the standard archetype in the miniseries, she's usually shown with a pair of headphones on and definitely loves making things harder for everyone present, but most especially her brother.
  • Establishing Character Moment: In the miniseries, Hyun-su sees her performing ballet on the rooftop as he contemplates suicide. She offers him a cigarette, and when he declines, bluntly tells him to look for another place to kill himself as committing suicide at Green Home will only cause more trouble for the residents.
  • Fiery Redhead: In the webtoon. She's spunky and willing to tell Hyuk off when she thinks he's being a jerk. In the series, her hair is a natural shade of black, but she's no less sharp.
  • Jerk with a Heart of Gold: She's the resident Snark Knight and has zero tact, but she does have a kinder side underneath the bitchiness.
  • It's All My Fault: She blames herself for her and Eun-hyuk's parents' deaths because she forced them to come to her ballet recital, which has also driven a wedge between them.
  • Pinky Swear: Asks Hyun-su to make one with her in the miniseries, the contents of which she keeps secret from him. It's later revealed that she made him promise to survive, not just for them, but also for himself.
  • Say My Name: In the miniseries, she starts screaming for her brother when she realizes he was lying about coming back.
  • Ship Tease: With Hyun-su in the miniseries.
  • The Snark Knight: A world-weary character who snarks indiscriminately? Absolutely fits.
  • Vitriolic Best Buds: With Ji-su. The two of them throw hateful comments at each other on every given opportunity, but when Jae-heon dies and Ji-su breaks down, it's Eun-yu who seeks her out and talks some sense into her. She's also shown crying when Ji-su passes out from shock on the operating table.

    Lee Eun-hyuk/Hyuk 
https://static.tvtropes.org/pmwiki/pub/images/eunhyuk.png
Played by: Lee Do-hyun

A relatively plain teen and Eun-yu's older brother.


  • Ambiguous Disorder: Hyuk is incredibly smart and is usually able to understand people very well, but he has No Social Skills, his filter is nonexistent, he can easily get distracted, and he has a very rigid and overly-pragmatic (and sometimes plain weird) way of thinking.
  • Big Brother Instinct: He's very protective of Eun-yu and tells Sang-wook to hide the fact that he's infected so as not to worry her.
  • Fatal Family Photo: He secretly takes his sister's last photo of them as a family and is shown looking at it in his final scene, which also doubles as his death scene.
  • The Friend Nobody Likes: Fellow survivors acknowledge him as a core member of the group but are quick to call him out for his apparent lack of empathy towards others.
  • The Gadfly: A Socratic version, Hyuk will ask questions or say cold things to test the people around him or motivate them to do the right thing, but very few people end up liking him as a result.
  • Go Out with a Smile: In the miniseries. Even as the building crumbles down, one of the very last shots we see of Eun-hyuk is him smiling, seeing as he knows his sister and their friends will be safe.
  • Heroic Sacrifice: At the end of the miniseries, he decides to stay behind once he gets his Deadly Nosebleed, knowing that his monsterfication is not far off.
  • Hidden Heart of Gold: Eun-hyuk often acts as if he's completely detached from the situation at hand, but anyone can tell that he's actually far more emotional and caring than he lets on. It's revealed that the cold and pragmatic attitude he puts up is to prevent anybody from panicking and, more often than not, to anger people into doing the right thing.
  • The Leader: He takes this role in the miniseries.
  • Otaku: He's a big anime and video games fan, and regularly talks about fighting the monsters in RPG terms. Eun-yu even states he had figurines before the crisis occurred.
  • Mirror Character: In the comics, he is very much this to Hyun. Both are young men who (surprisingly) went through some hardships in life, were big nerds (even liked the same stuff !), both were less than ideal individuals who were nonetheless good where it mattered, and both were monster infected who used their respective transformations to protect others.
  • No Social Skills: Deconstructed. Prior to the outbreak, he was isolated by his classmates and never learned tactfulness. As a result, survivors are quick to question his motives and is heavily mistrusted, thanks to his pragmatic way of thinking.
  • Not So Stoic: In the miniseries, Eun-hyuk's calm facade actually breaks multiple times.
    • While cleaning Min-ju's blood off his glasses, he's visibly shaken at having been unable to prevent the deaths of two people, even though he couldn't possibly have done anything to save them.
    • He's clearly teary-eyed when Jae-heon asks him to torch the elevator with him and the monsterized Mr. Kim inside.
    • He screams when Sun-young is killed in front of him and falls to his knees in front of her corpse.
  • Secret Test of Character: When Eun-hyuk sends Hyun and Sang-Wook to get Du-sik and the kids, he asks Hyun to focus on Du-sik, even at the price of Sook-yeong and Yeong-sook's lives ... but only to see if Hyun is the type of person to sacrifice children.
  • Smart People Wear Glasses: He's the smartest person amongst the survivors and wears glasses.
  • Those Two Guys: He develops this dynamic with his right hand man, Sang-wook. In the miniseries, Sang-wook's role is relegated to Yi-kyung and she becomes something of a big sister figure/advisor to him instead.
  • Uncertain Doom: At the end of the first season, he's shown to be having a massive nosebleed right as the apartment building is getting decimated by the military outside. Whether he'll survive to see Season 2 and be like Hyun-su after resisting the monsterization for 15 days remains to be seen.
  • Vitriolic Best Buds: With Cha Hyun-su in the webtoon.

An intimidating man who isn't as frightening as he appears.


  • Adaptational Jerkass: Ties up a man in his apartment and tortures him in the miniseries (although once said man's deeds are revealed, his actions are proven to be justified). He's also more distant towards his fellow survivors.
  • Bruiser with a Soft Center: He's one of the group's heaviest hitters, but he's especially gentle with Yu-ri and the kids. In the miniseries, he's especially protective of Yook-seong and even tells him to close his eyes so he doesn't have to watch Sang-wook kill a man.
  • Comfort the Dying: Even though he's dying himself in the miniseries, Sang-wook uses his final moments to reassure Yu-ri, insisting that even though she killed Kap-soo the rapist, it doesn't matter because the man no longer had any humanity left in him. He also makes the effort to intertwine their fingers so Yu-ri doesn't have to be die frightened.
  • Death by Adaptation: In the miniseries, he dies with Yu-ri before they can drive off to find more asthma medication for her. However, he shows up again at the very end, albeit with his body having been taken over by the Puppetteer Parasite monster.
  • Draft Dodging: In the miniseries, two gangsters call him out for holding them at gunpoint with the safety on and he responds that he didn't serve in the militarynote . Instead, he knocks them out with good ol' Pistol-Whipping.
  • Expy: In the webtoon—give him a sport coat and he's basically Kazuma Kiryu, down to the personality traits.
  • Face of a Thug: Bulky and intimidating to the point that Eun-yu sometimes calls him 'Mr. Mobster', but he's definitely an ally.
  • Good Is Not Soft: Sang-wook will retaliate if he feels his or the others' lives are in danger, but if you earn his respect, he'll show you Undying Loyalty.
  • Gotta Kill Them All: Sang-wook's personal goal in the webtoon is to kill every monster in the apartment complex for safety reasons.
  • Hates Being Touched: In the miniseries, he chokes Yu-ri upon waking when she makes the mistake of treating him while he's unconscious. He then tells her never to touch him. Averted later on when she reprimands him for his devil-may-care approach towards living and he asks her to help him clean his wounds.
  • Heroic Build: Sang-wook is very muscular and strongly cares about everyone in the group.
  • Made of Iron: In the miniseries. The only thing that downs him for good is when Ui-myeong shoots at him and Yu-ri when they try to escape.
    • The Starving Monster takes a huge chunk out of his shoulder and even then, he has more than enough strength to throw her through a wall and kick her repeatedly until she stays down.
    • He also gets hit in the head multiple times with a hammer and even though he passes out from having acquired multiple wounds by that point, he's more or less fine the next time he wakes up.
    • When The Beefcake swats their van aside, Sang-wook recovers fast enough that he's able to cut an unconscious Yu-ri out of her seat and, despite bleeding copiously himself, is perfectly capable of carrying her to safety before the car explodes.
  • Muscles Are Meaningful: When Baek Ho-yeon challenges Sang-wook to a fight, Sang-wook easily beats him because he's 20 kg heavier.
  • Kill Tally: Sang-wook keeps track of each monster he kills with a marker tally on his arm.
  • Police Brutality: He used to be part of the police force, only to be let go when he beat up a suspect to the point of nearly killing him.
  • Ship Tease: With Yu-ri in the miniseries. He quits smoking when he finds out she has asthma and willingly lets himself be treated by her. Averted in the webtoon, where they're an Official Couple instead.
  • Those Two Guys: He develops this dynamic with Eun-hyuk over the course of the story. In the miniseries, he forms this dynamic with Jung Jae-heon instead, even going so far as to tell Jae-heon a bit about his past.
  • Undying Loyalty: He may be willing to question Eun-hyuk's motives, but he will still follow his orders without reservations.
  • Younger Than He Looks: Yu-ri thought he was in his 40s when he's only 32.

A young man whose biggest concern was not being able to do his skin care routine.


  • Attention Whore: His monster form. It must be validated of its beauty every few seconds.
  • Dirty Coward: Refuses to fight the monsterized security guard and instead barricades himself in his room. Averted in the miniseries where he's present, but too stunned to do anything after watching Jae-heon sacrifice himself.
  • Mind Rape: Saying that his monster form isn't beautiful causes Hyun to go down with a massive headache.
  • Spared by the Adaptation: Doesn't succumb to monsterization in the miniseries.

  • Put on a Bus: In the miniseries, her dog Bom suddenly goes missing and she spends a while trying to find him.

  • Hidden Depths: His interactions with his inner monster heavily imply he is fully aware he is a horrible person and feels a level of remorse over his terrible treatment of his wife. He was however to self-centered and idiotic to change before it was to late.
  • Laser-Guided Karma: He immediately wanted to kick Hyun-su out of the apartments after the latter reveals his monsterfication. Not long after, he begins to show signs of monsterfication himself and is locked up with Hyun.
  • Nice Job Breaking It, Hero: Raises the building shutter, which lets a monster into the building and kills a survivor, leading to Eun-hyuk and Sang-wook (or Yi-kyung in the miniseries) to risk their lives trying to fend it off.
  • Sanity Slippage: Locking him up in a room as an infectee doesn't do wonders for his mental health.
  • Tragic Monster: Only in the webtoon. After succumbing to monsterization, he regains a sliver of humanity to express remorse for how he had treated his wife, and allows her to kill him.

The leader of a gang of thugs that attacks Green Home.


  • Ax-Crazy:
    • In the webcomic, Joon Shin is a remorseless mass-murderer who multilates corpses and feeds them to the monsters. He is also implied to be pretty unstable in general, given that he assaults Hyuk for mildy bothering him and flashbacks show him going to into rages when fighting monsters.
    • The live-action series also Implies that he is this. See No Kill like Overkill.
