* CharacterDevelopment: 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.

This is the Characters page for the ''Webcomic/SweetHome2017'' webcomic on ''Website/{{Webtoon}}'' and [[Series/SweetHome2020 the miniseries based on it]]. Currently under construction.

* DropTheHammer: How he dies.

** 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.]]

* NiceGuy: 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.]]

* DeaderThanDead: 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. She later reappears in Season 2, but is rammed by a military vehicle and almost incinerated when the Blind Monster intervenes, leaving her fate unknown yet again.

* HiddenInPlainSight: Eun-hyuk is actually seen early in Season 2 when the party returns to the Green Home apartments - but only in his cocoon, which he emerges out of in the ending of Season 2.

* OutlivingOnesOffspring: In the miniseries, Min-ju manages to make her way home but dies at the hands of the Tongue Monster before she could even reach the entrance.]]

* BeautyIsNeverTarnished: Like Yi-kyung, he gets abused in all kinds of ways during the series but heals nicely from his injuries and remains handsome throughout the series.

* DoubleStandardRapeFemaleOnMale: Ha-ni, one of the survivors not taking refuge in the stadium, basically plans to do this to him even though she ends up not going through with it.

* GeniusSlob: He was already unkempt looking during his introduction, but he takes it even further in the TimeSkip by growing his hair out, drinking rubbing alcohol, and constantly wearing the same ragged and dirty lab coat.

* ParentalAbandonment: She was abandoned by Yi-kyung immediately after her birth, as Yi-kyung thought she had given birth to a monster, but when she appeared to be growing like a regular human girl Yi-kyung took her back from Hyun-su and raised her.

Although the same thing happens in the miniseries, Mr. Han gives him a CooldownHug that turns Hyun back into a human, albeit at the cost of the inventor's life.]]

** [[spoiler: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, [[spoiler: 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.]]

* DarkAndTroubledPast: [[spoiler: 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.]]

* EarnYourHappyEnding: [[spoiler: 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.]]

* NakedOnArrival: [[spoiler: In the final chapter, Hyun came out of his cocoon as a naked, evolved, and humanoid monster.]]
* NiceGuy: Flashbacks showed that he used to be this but something happened that made him a hikikomori. [[spoiler: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.]]

* OneWingedAngel: [[spoiler: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.]]
* PowerAtAPrice: The more Hyun uses his powers, the more likely he'll become a monster. [[spoiler:In chapter 138, he finally gives into his monsterization for the power to kill Joon Shin and protect his friends.]]

* ShockStick: Hyun's main weapon is a broken mop handle with a knife attached to it, which Mr. Han later upgrades into being able to conduct electricity. In the webtoon, [[spoiler:it eventually becomes a part of his monster form]].

* SpoiledBrat [=/=] UsedToBeASweetKid: 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. [[spoiler: Deconstructed later on with TheReveal 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.]]

* SuperStrength: The more his infection progresses, the stronger he gets.[[spoiler: 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.]]

* TenderTears: [[spoiler: 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.]]
* TraumaInducedAmnesia: In the miniseries, [[spoiler: 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.]]
* UnexplainedRecovery: [[spoiler: Ui-myeong, possessing Sang-wook's body, petrifies Hyun and leaves him to die early in Season 2 of the miniseries. He later appears after Yi-kyung gives birth with no explanation as to how he was un-petrified.]]

* CartwrightCurse: [[spoiler: 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.]]

* InelegantBlubbering: [[spoiler: 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.]]
* LoveHurts: Ji-su's boyfriend [[spoiler: committed suicide]] and Hyun [[spoiler:turns into a monster in front of her to save her life in the last few chapters.]] [[spoiler: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.]]
* MercyKillArrangement: In the miniseries, Ji-su agrees to kill Hyun if ever he turns, only if he does the same for her. [[spoiler: She almost goes through with it in Episode 10, only to be stopped by Eun-yu.]]

** [[spoiler: 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 [[spoiler: Hyun being unable to warn the survivors in time of the infected security guard's existence, which results in Jae-heon's death.]]

* RupturedAppendix: [[spoiler: 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.

* ShipTease: She and Jae-heon have their moments in the miniseries.

* TraumaticHaircut: Her hair becomes shoulder-length in the miniseries after [[spoiler: a monster grabs on to her hair in the car park and Jae-heon has no choice but to slice it off.]]

* VitriolicBestBuds: 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 [[spoiler: Jae-heon dies, Eun-yu is the only person shown actually comforting her, first with chocolate, then with somewhat kind words.]]

* CoolDownHug: [[spoiler: Administers one to Hyun-su in the miniseries after his monsterization worsens during an eclipse.]]

* DiedInYourArmsTonight: [[spoiler: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 OneWingedAngel form in the process.]]

* {{Foil}}: To Hyun. Both were people who "lost" their loved ones ([[spoiler: Dusik having being abandoned 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 [[spoiler: infected]]. However Dusik is consistently a [[NiceGuy great fellow]], while Hyun was an [[{{Jerkass}} complete asshat]] [[CharacterDevelopment before he started mellowing out again]]. Dusik was physically disabled, while Hyun was not. Dusik was also much OlderAndWiser than Hyun.

* HeroicSacrifice: In both the webtoon and the miniseries, albeit in different ways. In the webtoon, [[spoiler: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 [[spoiler:giving Hyun-su a CooldownHug while the latter is in a fully berserk monster mode]].

* ThrowingOffTheDisability: [[spoiler: 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.]]

* AnguishedDeclarationOfLove: [[spoiler: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.]]
* AnArmAndALeg: [[spoiler:The monsterized Mr. Kim slices off his left arm in the miniseries.]]

* HeroicSacrifice: [[spoiler:In the miniseries, he [[TakingYouWithMe 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.]]

* NiceGuy: 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. [[spoiler: When he dies, all of the survivors present are in tears, including [[TheStoic Eun-hyuk]]]].
* OddFriendship: 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. [[spoiler: 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.]]

* SacrificialLion: [[spoiler: He is the first sympathetic character killed by the monsters to show that AnyoneCanDie.]]

[[folder:Kim Sook-yeong/Sook and Kim Yeong-sook/Yeong]]

* DeaderThanDead: [[spoiler: 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}}: [[spoiler: In the miniseries, she almost succumbs to monsterization while cooking dinner and ends up chopping off her fingers as a result.]]

* LivingMacGuffin: [[spoiler: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.]]

* MercyKillArrangement: In the miniseries, she asks Mr. Han to kill her if she turns. However, [[spoiler: 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.]]

* BloodFromTheMouth: Happens to him in the miniseries when[[spoiler:he is about to let himself be crushed by The Beefcake.]]

* HeroicSacrifice: [[spoiler: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.]]

* PassedInTheirSleep: [[spoiler: 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.]]

* DeathByAdaptation: [[spoiler:Dies alongside Sang-wook in the miniseries from gunshot wounds before they could drive off to find more asthma medication for her.]]
