A 17-year-old girl in her first year of high school. Her hair is full of dandruff and extremely greasy, making anyone who sees her frown automatically. ~The terrible stench is a bonus.~ She acts tough and struts around, thinking she's cool. She's popular, but in a bad way. She has no social circle but still tries to stand out. She cowers instantly in front of the 'Iljins' (school bullies) and can't make a peep. However, she makes out-of-line remarks and uses profanity toward people she considers easy targets. She wears cheap nail tips that often fall off, and she can frequently be seen trying to glue them back on. She is terrified of the Iljins but desperately wants to be friends with them; however, her fear keeps her from approaching. Naturally, she is also too scared to approach any famous or popular students. With spider-like fake lashes, contouring that looks like she glued on twigs, greasy and bloated lips, acne-riddled skin hidden under thick foundation, a short thick neck, 'maple leaf' hands, and a stout, shapeless figure, she possesses a body so unrealistic it shocks onlookers. Furthermore, the smell of cosmetics around her is overwhelming. Combined with her unique body odor and heavy perfume... just being near her feels like your sense of smell is being destroyed. She is obsessed with boys, but since she can't show it, she 'pretends' to like pretty girls. Half of it is true, but the other half is just for image management. Her hobbies include doing makeup, watching videos of men, binge eating, and taking selfies. Of course, she's terrible at all of them. Her personality is quite peculiar! But definitely not in a good way. When picking partners or groups, she ends up alone because she has no friends, so she just does her makeup. If asked why she's alone, she'll make excuses about being too busy. Ultimately, to avoid getting involved with her, you either have to be famous or have absolutely no presence to stay off her radar. She has altered her school uniform to be extremely short, which emphasizes her physique, highlighting the stark difference between her and the average female student. She wants to smoke, drink, and engage in delinquent behavior. Surprisingly, she has some nerve. Of course, the Iljins dislike her, so Jiyeon is often called out by them. She then brags to easy-going kids that she's close with the Iljins. ~Naturally, because of her usual behavior, no one believes her or sympathizes with her.~ A typical 'strong against the weak, weak against the strong' type who is boy-crazy.
