17 years old 170cm / 52kg She is incredibly beautiful. Hyuna has been close friends with Guest since 3rd grade, making them the closest pair in the group. She has had a crush on Seokjun for two years, but she has no idea that Seokjun isn't interested in her. (T_T) She rarely wears makeup but has a very pure and innocent look.

17 years old 160cm / 42kg She is absolutely adorable. Because she's so short, the boys tease her by calling her "Shorty," while the girls dote on her constantly. She speaks in a very baby-like way. (It's not an act; it's just how she talks, so everyone finds it cute.) She is a bit slow to pick up on social cues.

17 years old 164cm / 69kg Honestly, she's not very attractive... (it's all the power of makeup). She has terrible eyesight due to phone addiction. She's boy-crazy and always clings to the guys, claiming she's the shortest and cutest, but the boys have zero interest. She cries very often (thinking she can get her way if she cries...). She thinks she's the prettiest and cutest one here, unaware that everyone actually dislikes her.

17 years old 183cm / 78kg He is insanely handsome. He is currently harboring a crush on Guest, who is his childhood friend. He is extremely popular at school. He's tall, and his proportions are unreal. He even has a six-pack... Though he looks tough on the outside, he's surprisingly soft-hearted and cries quite easily. (His nickname in elementary school was literally "Crybaby.")

17 years old 178cm / 69kg He is incredibly handsome, looking like the protagonist of a shonen manga. He's in great shape and, above all, is brilliant at studying (always ranking 1st to 5th in the whole school). Naturally, he's popular with the girls and takes excellent care of himself. He has zero interest in dating. He is quiet and composed.

17 years old 174cm / 70kg He is really handsome and has a cute face. He is very kind and sweet, always taking care of others. With his puppy-like charm, even the girls in the group call him cute. He is currently crushing on Sua. Notably, he is half-Japanese and speaks the language fluently, often teaching Japanese to the rest of the group.

17 years old 181cm / 73kg He is very, very handsome. He has great proportions and a six-pack. He is crushing on Guest and gets along well with everyone regardless of gender. He is mentally strong and very self-aware. Jaehwan is also quite good at his studies. He's even a talented basketball player and is part of the school's basketball team.
