->''"Is grinding my job now?"''
-->--'''Han Jee-Han'''

What would happen if your world [[SuddenGameInterface suddenly turned into an RPG]]? What if you could level up, raise your stats, and embark on a lifetime of adventure, loot and genre tropes galore?

Enter Han Jee-Han, an 18-year-old OrdinaryHighSchoolStudent. He's recently broken through TheMasquerade and discovered that the world is full of dangerous monsters and people with supernatural gifts hiding in plain sight.

He is no mage, martial arts master, or monster summoner. His own power is meager in comparison, but it is unique: A [[IKnowMortalKombat lifetime commitment to gaming]] meant his gift manifested in him becoming a living RPG character. Whenever he looks at people, [[RPGMechanicsVerse he can see their titles, level, and stats.]] He can tangibly and immediately raise his skills and overall stats by performing tasks and gaining experience. Monsters that everyone else considers a dangerous nuisance [[MoneySpider inexplicably drop equipment he can use.]] His injuries recuperate by [[HyperactiveMetabolism consuming ordinary food]] or [[TraumaInn resting overnight.]] He is able to learn skills way above his apparent PowerLevels [[MinMaxing by allocating his stats correctly]]. And he is prepared to take on this brave new world through grit, GenreSavvy, copious amounts of LevelGrinding and the fact that none of his opponents can figure out how video game logic works.

A Naver webcomic. English translations can be read on most major manga websites and on the recent [[http://www.mangahere.co/manga/the_gamer/ official Naver translations]]
!!This webcomic provides examples of:
* AwesomenessByAnalysis: Part of the comic's appeal is Jee-Han figuring out not only how do his powers work, but also how to [[MinMaxing min-max them]] [[TheMunchkin to gain an edge]].
** His 'A Gamer's Mind' ability allows him to be this, making him able to keep calm and think logically in dangerous and stressful situations (like combat) and making him immune to psychological status effects.
* BallsOfSteel: The [[RainbowPimpGear ogre's panties]] are nearly indestructible and negate damage below a certain threshold, [[BreadEggsMilkSquick they have also been worn by an ogre already]]. Protection of his [[GroinAttack sensitives]] makes Jee-Han ''consider'' wearing them anyways, but ultimately decided to sell them.
* BattleAura
* BlackMarket: The Abyss Auction used to trade through one.
* CutLexLuthorACheck: Played with: Abilities ''can'' be used to [[MundaneUtility make money]] in the {{Muggle}} world, but only as long as is doesn't threaten the {{Masquerade}}. Using discrete abilities to -for example- make your wares more eye-catching, appealing, or just plain better is perfectly fine even if all of your clients are {{Muggle}}s. Being too overt however (like making yourself win the lottery) will make ''the world itself'' kill you.
** Jee-Han also gives the RandomDrops to Shin Sun-Il to sell them (or extract the magic out of them), netting him large amounts of money.
* DeflectorShield: The Mana Shield ability works like this. With a little grinding, Jee-Han might be able to make it permanent.
* DishingOutDirt: [[SummonMagic Gnome]], obviously; Jee-Han provides the MP, while [[CuteMonsterGirl she]] takes care of the actual casting. Gaining the ability to summon Gnome also gave Jee-Han the 'Earth Element Affinity' status, improving his own use of the element.
* DramaPreservingHandicap: The author's answer to make sure that Jee-Han doesn't become such an obvious GameBreaker thanks to his Gamer ability is to make sure that [[IdiotHero his Wisdom stat remains relatively low]] so that Jae-Han doesn't make the necessary, or completely correct, decisions regarding how to power up his abilities. For example, his lack of Wisdom causes Jee-Han to rush into things without fully thinking the process through such as suddenly dumping all his extra stat-points into Intelligence despite knowing that it would help build his judgement, and thinking-process, if he put points into Wisdom.
** Somewhat justified though; Since Jee-Han has already put a lot of points into Int, it's very difficult to get extra Int points by doing regular actions or training. Meanwhile, Wisdom, Strength, and all his other stats can be increased relatively easily by grinding related actions. So, since he can't effectively grind Intelligence anyways, he dumps all his stat points into it to artificially raise it. The problem comes in with how difficult it is to grind Wisdom, since making intelligent decisions requires a good Wisdom to begin with.
** The problem is starting to be addressed with Jee-han investing points in Wisdom as of chapter 66.
* EmpoweredBadassNormal: It's possible for people to develop abnormal powers through training. Jee-Han realizes that one of his longtime best friends is like this based on his title and unusually high level.
* GayOption: In the WhatIf extra where the main character's life becomes a dating sim, Shin Sung-Il is on the list of datable characters.
* {{Foreshadowing}}: As expected, a few chapters after Jae Han is warned about the possibility of Mana Farms coming after him in order to exploit his powers, a pair of people from the Abyss who capture people and sell them to the farms appears and comes after him.
* HiddenDepths: Jee-Han can't see [[spoiler:his mom's]] level. This is indicative of very powerful characters; the only others he can't see are BadassGrandpa Shin Sun-Oh and Sung Ma-Hyun, one of the big cheeses in the underworld's BlackMarket.
* HowDoIShotWeb: The first few issues mostly deal with Jee-Han learning how his new abilities work.
* HyperactiveMetabolism: Justified and Lampshaded. Food heals HP, so the main character responds to a particularly damaging attack by immediately pulling some bread and milk out of his HyperspaceArsenal and frantically stuffing them down his mouth as fast as possible... in the middle of a fight.
* ItsASmallNetAfterAll: It takes less than an hour of research for Jae Han to find the website that the Abyss Auction works through.
* {{Irony}}: Despite how Jae-Han's obsession with games is mocked, along with his gamer ability (before they realize how much potential it has), some of the characters who appear later do look like RPG characters.
* IWantThemAlive: In chapter 34, a pair of what are essentially human traffickers with superpowers appear with the intent of kidnapping Jae Han and selling him to a Mana Farm.
* KnowledgeBroker: Along with goods and lives, the Abyss Auction deals with information.
** They also deal in rare objects that can be found in the Abyss. Poong Sae-Young warns Jae Han to be especially careful after hearing about him because if they discovered more about his ability, they might want to abduct him for it, or for a Mana Farm--where Ability users are held prisoner and have their mana siphoned to be bought and sold.
* LevelGrinding: Han Jee-Han does this constantly, both to increase his overall level and the levels of individual skills.
* LevelUp
* MagicMissileStorm[=/=]RainOfArrows: Spinning Mana Arrow becomes cheaper and creates more projectiles [[EvolvingAttack the greater its level grows]], and it's really fast, too. It's no surprise that it becomes Jee-Han's most used attack.
* {{Masquerade}}: Enforced. If you break it, the world itself will kill you. But you can use it to make a living off of it.
* ManaShield: Shin Sun-Il suggests that Jee-Han learn this ability, saying that it's common among western ability users. Thanks to Jee-Han's Int-based build, focus on defense, percentage-based MP regeneration, ''massive'' MP reserves, SummonMagic, and low-cost DeflectorShield, it would help to make him even harder to kill.
* NewTransferStudent: [[spoiler: Kwon Shi-Yun]] suddenly transfers to Han's class not long after he encounters her, along with [[spoiler: Hwan Sung-Ah]]. For extra comedy, [[spoiler: Hwan Sung-Gon]] transfers as a teacher.
* ObstructiveCodeOfConduct: The Interference Law prevents those with powers from affecting the real world with the penalty of death. The extent of the law is rather vague but it basically boils down to 'don't do anything too obviously supernatural'.
* OurZombiesAreDifferent: They come off as the typical slow zombie. They're actually spirits of the dead given shape inside an Illusion Barrier. Meaning that they don't have physical bodies and simply dissolve after being destroyed leaving nothing behind.
** Except when they're destroyed by Han, they drop items due to his ability.
* PhantomZone: All ability users have the ability to create 'Illusion Barriers' where they can fight without affecting the real world (or breaking the {{Masquerade}}.)
* PowerGlows
* RankInflation: Chapter 29 introduces two ranking systems - there's an A-E system used by Hwan Sun-Gon and his summons, and also a high-mid-low system used by Chunbumoon.
* RainbowPimpGear: One piece of powerful equipment Jee-Han finds is a pair of ''ogre's panties''. The description even helpfully notes that it's been worn by an ogre before. He declines to wear it.
* RPGMechanicsVerse: The Gamer ability turns Jee-Han's life into this. It's a weird example, since the setting as a whole apparently isn't one; it's more that his superpower is to interact with the world as if it were a game.
* RuleSixtyThree: In-universe for a WhatIf [[http://www.mangahere.com/manga/the_gamer/c021/26.html extra]].
* ShoutOut: ''VideoGame/HalfLife'', ''Webcomic/TowerOfGod'' and - of course - ''TabletopGame/DungeonsAndDragons'' are referred to by name.
* ShipTease: Of varying degress:
** There's been some slight teasing with [[FieryRedhead Shi-Yun]], even though she's been mostly OutOfFocus. Her strait-laced manner actually broke when she [[ThatCameOutWrong unintentionally said something potentially suggestive]] to Jee-Han. [[note]] For context, Jee-Han helped her and she insisted on rewarding him for it, since she couldn't believe that Jee-Han helped her out of the goodness of his heart. She even offered [[ExactWords her body]] as a reward if he so desired--she just meant something completely different from what Jee-Han and quite probably the reader expected.[[/note]]
** There's been comparatively more with [[TheTease Sae-Young]]. Since she and Jee-Han are more or less {{Childhood Friend}}s, Jee-Han can't help but notice Sae-Young's growth into [[MsFanservice quite an attractive young woman.]] Her skimpy choice of attire certainly doesn't help, and neither does her [[TheTease provocative manners or habit to tease Jee-Han for all its worth.]]
** By far, Jee-Han has had the most ShipTease with [[IllGirl Sung-Ah]]. Jee-Han immediately sympathizes with her plight, and realizing that his ability can help her and even potentially save her, he wonders if he was born just for the purpose of helping people like her. Sung-Ah's normally sullen personality and her condition serve to make scenes featuring her very poignant, and Jee-Han always, without exception, does his utmost to be nice to her and help ease the burden of her curse every time they meet. He strives to allow her to experience things normal girls get to do all the time that she can't because of her extremely frail body and because of her father keeping her close to protect her. Most blatantly, [[spoiler:when she offered to repay a favor and he thoughtlessly asked for a date, '''she accepted''']]. [[note]] Though, her instant approval of his request is most likely because it was her first one too.[[/note]] And later, Jee-Han vows that one day he will save her, [[spoiler:and Sung-Ah is ''moved to tears''.]]
** The [[RedBaron Witch of]] [[NamesToRunAwayFromReallyFast Carnage]], aka [[ExactlyWhatItSaysOnTheTin Loli]]kiano Mistream took an instant liking to Jee-Han, openly flirting with him in the way an older woman would with a younger man and even giving him her number. After the battle with the Black Rock clan, she "marked" him by [[spoiler:stealing his first kiss.]] Talk about coming on strongly.
* SomethingOnlyTheyWouldSay: Jee-Han convinces his best friend, Shin Sun-Il, of who he is... by making a ridiculously bad Star Wars joke while Shin Sun-Il is choking him and demanding to know his real identity.
** The same happens a bit later with Sae-Young, under basically the same circumstances. He convinces her that he is the real Jee-Han by...[[spoiler:revealing he knew she wears black lace silk panties since several years ago]],[[note]]He was about to say 2nd year of either Junior or High School, but got interrupted mid-way by a raging woman.[[/note]] something only he would know since he went into her room once without her permission.
* SuddenGameInterface: The TropeCodifier.
* SummonMagic: Black Summoner is Hwan Sung-Gon's ability.
** Later, Jee-Han gets into it by summoning [[CuteMonsterGirl Gnome]].
* TimeStandsStill: Illusion barriers can have this effect, though they don't last long.
* UnskilledButStrong: Shin Sun-Oh wants to make sure that Jee-Han averts this. He wants Han to come train with him even though Han insists that he's already figured out how to become exponentially stronger by exploiting his ability. Shin then rebukes him by stating that raw power is useless without skills and experience.
* UnusuallyUninterestingSight: Both Hwan Sung-Gon (summoner guy) and Kwon Shi-Yun (red haired girl) transfer into Jee-Han's school as a teacher and a student, respectively, but no one besides Jee-Han feels that anything is amiss. Especially egregious is how no one seems to care about Hwan's MIB style attire.
* YearInsideHourOutside: Illusion barriers. The Chunbumoon's training area has a time flow ratio of 10:1.
