Han Jee-Han is the main character of this story. Jee-Han has recently discovered that he has a natural ability called The Gamer. This ability makes him experience his life in a game-like setting which was derived from his gaming addiction.
Before he gained the ability known as “The Gamer”, Jee-Han had no motivation or dreams to accomplish anything. Like many teenagers at his age, he had no idea what he wanted to do with his life and sought for a way to become an important person in society.
Because of his obsessions with video games, Jee-Han can usually relate most things he learns about the Abyss and the Gaia Theory back to video games which make it simpler for him.
Though he’s not a complete coward, Jee-Han has shown his bravery to engage himself in combat. After getting accustomed to engaging enemies and leveling up, Jee-Han has become much more confident in his abilities .
Thanks to the incredibly useful functions that his natural ability gives him (such as creating drops from nothing, allowing him to learn skill books instantly, and obtaining passive skills), Jee-Han’s ego has gotten noticeably big. Sun-II has frequently expressed distress at the unfair advantages that Jee-Han gloats about and has developed somewhat of a god complex (comically of course). However, after witnessing the overwhelming power of those who are veterans in the Abyss, Jee-Han’s ego about his ability has been lowered and he has begun to see how truly small he is.
The Quest Above My Head
Training arc - The story began with Jee-Han explaining how much his life is like a video game. He uses his ability to gain quests, EXP, and levels. He wasn't aware of how, or why, his life suddenly became like this. Just that he first noticed when a status window explained he had gained a level, and he put the five stat points he gained into STR (Strength) making him a bit stronger. At the end of the first chapter, it is explained he can also gain stat points by performing tasks that increase them (In Real Life). Such as studying, and exercising.

Han Jee-Han proceeds to have an encounter inside of an Illusion Barrier that he accidentally entered containing Hwan Sung-Gon and Kwon Shi-Yun. Jee-Han attempted to escape since both parties were higher level than he was, only to be captured by one of Sung-Gon's creatures, and used as a pawn to force Shi-Yun to fight Sung-Gon's summoned creatures. Jee-Han escapes and defeats Sung-Gon's creature gaining him two levels. After which he is questioned by Kwon Shi-Yun. Later Jee-Han talks with his friend Shin Sun-il about his experience, which leads Sun-il to threaten Jee-Han believing him to be an impostor. Jee-Han quickly disposes of that fear and learns about Illusion Barriers. Gaining him three skills in the process. Jee-Han also learns that his powers were granted to him from "Gaia", the spirit of the earth and that the powers "Gaia" grants are usually related to an experience, or trait, a person exhibits. For example, someone who almost died of drowning might gain water related powers since the experience had a huge impact on their life. Meaning Jee-Han got his gamer power because of his addiction to video games.
Jee-Han proceeds to get caught once again in an illusion barrier filled with zombies. Using the skills he's developed so far Jee-Han fights the zombies and acquires a level and an object known as a spirit stone.

Jee-Han later goes to see Sun-il. Worried his friend is injured, or even dead. He is then interrogated by Poon Sae-Young about his identity, similar to how Sun-il questioned his identity until he also disposes of Sae-Young's fear by revealing a secret he had learned about her. Which resulted in Sae-Young hitting him in the neck, and becoming red faced. Sae-Young brings Jee-Han to Sun-il. Revealing he is alive, but injured. Jee-Han, using a book besides Sun-il, gains the skill "Yun-hon Soul recovered" (later changed to "Yun-hon recovery". Probably due to the redundancy "hon" means "soul". so there was no point in having "soul" in there twice), and heals Sun-il instantly. A feat that is impressive to all but Jee-Han who believes it a common thing.
Jee-Han is later returned to Sun-il's residence to test his skill gaining knowledge. He is given various books by Sun-il's grandfather Shin Sun-Oh. Jee-Han learns a variety of skills that all increase his stats, and is even given weapons to go with the various weapon mastery skills he's given. Jee-Han then ventures into various illusion barriers with Sun-il where the two encounter bosses that drop healing potions, money, and various other objects.

The majority of these objects are given to sell for large quantities of money. Jee-Han is also introduced to a company called "Abyss Auction", and the world of "Abyss" in general. Abyss is an underground world of those who have powers similar to Jee-Han. Jee-Han constantly wrestles with the issue of joining the Abyss or remaining in the real world. To date Jee-Han has accepted even if he does not indulge in the Abyss he must become strong so Abyss people do not kill him.
Using Abyss Auction Jee-Han gains a multitude of items and skills to complement his goal with becoming "A Mage as all terms are used at some point in the story. Jee-Han also follows this goal by leveling up his INT (Intelligence) and his WIS (Wisdom) using his stat points. It is revealed that when his base stat levels become 50, 100, and 200, Jee-Han gains additional skills. Though Jee-Han doesn't seem to grasp this concept despite hitting 50 twice, 100 once, and 200 once. Jee-Han's power is considered impressive at several points, though it appears the people who consider that power "impressive" are still stronger than he is.
The Black Soul Arc - After meeting Hwan Sung-Ah Jee-Han learns she is afflicted with something called a "Black Soul". It is revealed to be an abnormality in certain people, and his highly coveted since people with "Black Soul" have the potential to become incredibly strong. As it is revealed that is the case with Hwan Sung-Gon. Jee-Han attempts to heal Sung-Ah of her Black Soul since Jee-Han feels bad about her affliction. It is revealed he is unable to do so and continues to train his Yun-Hon Recovery skill to be able to do so. At one point Jee-han and Sung-Ah go on a date together. Sung-Ah seems naive to the way a date works, but Hwan Sung-Gon does not. as he follows the two from a distance and subjects Jee-Han to blood lust whenever he gets close to Sung-Ah. This results in a new skill being created, and leveled up five times, from the amount of blood lust Jee-Han is subjected to.
The arc continues Han Jee-Han's training arc. Letting him level up his various skills, stats, and his overall level. Jee-Han also encounters Lolikeano Mistream, "The Witch of Carnage", and her companion "Great Wolf" when Jee-Han and Sung-Ah are targeted by two Abyss warriors. Jee-Han is unable to damage the two, but able to escape them with Sung-Ah. Lolikeano reveals these two warriors are weak, and disposes of them, per her contract with Sung-Gon. Lolikeano then demonstrates an interest in Jee-Han. Even inviting him out on a date. Jee-Han refuses and is given her card with her phone number before leaving.
Jee-Han encounters Lolikeano once more inside of another illusion barrier where she is being hunted by another group called "The Black Rock". Despite Jee-Han being incredibly weaker, he assists Lolikeano and her warrior in defeating this group. Doing so allowed Jee-Han to level up and gain a new skill. Jee-Han also became "marked" When Lolikeano kissed him. After leveling up his skills more Jee-Han came upon a battle where many Abyss warriors were attempting to harm Hwan Sung-Gon and Sung-Ah. Jee-Han, along with Kwon Shi-Yun arrive to aid them. Though aside from getting rid of weak enemies, they are mostly unable to help, until the pivotal moment when Jee-Han heals an injured, and nearly beaten, Sung-Gon.
It is revealed Sung-Gon is under attack from a group called "The Company" which, as the name implies, is intent on making vast amounts of money. They are revealed to be intending to create a Philosopher's stone using the Black Soul of Sung-Ah. The Company's main power is revealed to be its vast fortune. Which, when purchasing land and objects, gives them complete control over what they've purchased. Though it appears there are exceptions to this rule. As Jee-Han is able to move freely despite the company purchasing the land. Implying the company must directly command what they wish, and aren't able to command all things.
Sung-Gon emerges victorious and asks to repay Jee-Han. To which Jee-Han states he only wishes books. Sung-Gon deduces it is for Jee-Han's ability to gain skills using books and agrees to supply Jee-Han with skill books. Though to this day, it is unclear if Sung-Gon has made good on his promise. Lolikeano makes the same offer and is asked to teach Jee-Han magic. A request that Lolikeano finds intriguing and agrees to take Jee-Han on as a pupil for one month.
The Age of the Great Labyrinth - After the battle with The Company, an unknown group creates a new mobile application game called "The Age of the Great Labyrinth. Jee-Han comes upon this plot after his training with Lolikeano when he comes across an entryway labeled as "DLC" (DownLoadable Content) for the Age of the Great Labyrinth. He ventures in, an act which enrages Sun-il, and discovers it is like a video game Labyrinth. He quickly clears the first floor being it is full of low level creatures. Gaining various objects, and money. It is revealed the Labyrinth is a creation from Abyss people to gather the power of imagination from people, and that gathering this much energy could create a "god".
It is revealed imagination power is used to create "gods" so that groups can use their gods to increase their own power or the power of their groups. It is then hinted this is the base for many forms of mythology in the real world. Though it is not confirmed that mythological gods were created using this technique. Jee-Han is told not to go into the Great Labyrinth and agrees since he is now able to create it himself. Though it is revealed that his creations are linked to the actual Great Labyrinth when Jee-Han finds Kim Yoo-Jin in a Great Labyrinth he created when she is pulled in by the game during her sleep. Jee-Han saves Yoo-Jin and gets her out of the Labyrinth. Jee-Han then proceeds to help Yoo-Jin become stronger so she can get out herself if she is ever pulled in again. Lolikeano makes all her training pointless when she enchants Yoo-Jin so the Class Rep cannot be pulled in again. Despite this Yoo-Jin is kidnapped by an unknown assailant, later revealed to be in Hyung-Jin the puppet master who controls metal woman-shaped puppets.
Jee-Han goes to save Yoo-Jin, an act which also enrages Sun-il, and battles Hyung-Jin. Though Hyung-Jin appears to be more powerful, Jee-Han is able to defeat him due to Jee-Han's ability to regenerate his mana (an act which even Lolikeano considers impressive). He outlasts Hyung-Jin and defeats him when Hyung-Jin is out of power. Jee-Han rescues Yoo-Jin and many others from Hyung-Jin's clutches, and debates on killing Hyung-Jin before Sun-il arrives. Jee-Han and Yoo-Jin are then offered to join Chunbumoon so instances like this will not happen again. As Chunbumoon is a highly respected, and feared, group in the Abyss. Jee-Han joins and is given the title "Chunbumoon's fool", while Sun-il's title is raised from "Chunbumoon's heir' to "Chunbumoon's victor". Implying the Chunbumoon have a ranking system with their members. Though it is not confirmed HOW one raises their rank, or how many ranks exist in the group.
Jee-Han, while out with Yoo-Jin, is come upon by Kwon Shi-Yun. Who becomes jealous of Yoo-Jin. After it is revealed Jee-Han kissed Lolikeano, and is called "A player" by Shi-Yun, Jee-Han is subjected by blood lust from both girls to the point his skill level to detect blood lust raises. After going to an amusement park, where Jee-Han uses Shi-Yun's naivety to subject her to wearing bunny ears, the group spends a day together having fun. While both girls secretly compete with each other for Jee-Han's affections. The group is then pulled into the Great Labyrinth, along with many other players, and told that this time there is a prize. Whoever clears the tenth floor first will get to keep their items and powers when they leave the Labyrinth. Though this prize does not apply to the group (since Jee-Han keeps whatever items he gets anyway, and Shi-Yun and Yoo-Jin have never been in the Labyrinth without Jee-Han) the three still attempt to clear the ten floors and do so quicker than the others since Jee-Han and Shi-Yun are incredibly strong.
