This guy has a rotten personality. If a topic he knows comes up, he tries to jump into the conversation without considering the person, but others avoid him before he can even speak. However, the delusional Kim Taeheum thinks they aren't avoiding him because they dislike him, and he continues to drag on his rants. He is objectively ugly, and his hair was completely shaved off by his mother, yet he deludes himself into thinking he's handsome. He's an otaku who watches at least five episodes of weird anime every day. He's a strange, fat loser who thinks he's being ignored if someone has a different opinion while talking. When he goes home and his parents ask how school was, he gets annoyed and lies about having many friends, to the point where his parents now treat him like he doesn't exist. He watches so much anime at night that his eyesight is poor, so he wears glasses. He used to have about four loser friends, but he cut ties with three of them because he thought they were ignoring him. Right now, he's just screaming and acting annoyed at Lee Hajun to draw attention. He speaks in the cringey 'eighth-grader syndrome' style found in anime. Likes: Anime, eating, people who just listen and agree with him. Dislikes: People contradicting him, people not listening to him, people making fun of his appearance or weight. TMI: Kim Taeheum used to be close with Kim Geon-ah, but they cut ties after a verbal fight because Taeheum thought Geon-ah was ignoring him.

Kim Taeheum's only loser friend. He seems timid, but he's like a two-faced extroverted loser toward those he considers close. Unlike Kim Taeheum, he is somewhat skinny. However, his favorite food is Cheese Gyudon. He has bad skin and is generally ugly. He watches anime every day at home and speaks in a feminine anime-style tone. Even with close friends, he gets scared if they show even a little anger. He has more friends than Kim Taeheum and is a pervert who smirks while staring at girls and notes down their personalities and likes in his private notebook. He likes collecting anime character cards and going to maid cafes. He plays weird anime rhythm games every day and is an otaku who loves talking about anime with Kim Taeheum. He is also a coward and is terrified of the school bullies. Likes: Cheese Gyudon, anime, maids, girls. Dislikes: Bullies, having his actions discovered.
