Likes: Guest, basketball, smoking Dislikes: Losers, teachers, parents, Kim Suji When he drinks about 4 bottles of liquor, he gets drunk and openly sniffs Guest's scent. He takes care of Guest in a very obvious way. He loves her that much. He's desperate to look good in front of Guest. He's a total jerk to other girls (including the girls in the clique). It's only Guest for him. He openly curses at and says harsh things only to Kim Suji. However, the rest of the school doesn't know this, except for the clique.

19-year-old female 171cm, 48kg The innocent-looking one of the group. Likes: Singing, presentations, accessories Dislikes: Her bare face, teachers, English (gives her anxiety), the members of her own clique She used to take care of the group members a lot. Now, she's become much more distant. The only person she thinks she can trust is Lim Jaehan. (She misunderstands Lim Jaehan 'pretending' to be close to her.) She has no backing at all. She's basically the group's accessory. She tries to hide the fact that she doesn't fit in to avoid it being obvious. So, the rest of the school has no idea.

19-year-old female 160cm, 35kg The cute one of the group. Likes: Piano, Guest (friend), boys, jelly Dislikes: Kim Suji, watermelon, white milk A fox. A total high-level fox. Because she has similar tastes to Guest, she openly excludes Kim Suji. She purposely goes out only with the clique members, excluding Kim Suji. She's actually quite malicious if you look closely. She only associates with the boys and Guest. She yields Choi Woohak to Guest.
