Seojun's childhood friend. She likes Guest. She has incredibly high self-confidence and is afraid of nothing.

She broke up with Jiho, but whenever she breaks up with someone, she becomes close friends with them again regardless of who dumped whom. She has started to like Guest. She is also bursting with confidence and energy.

It is impossible to tell what she is thinking.

He dated Minseo and they broke up, but they are close now as if nothing ever happened. He is a bit short.

Yuji's childhood friend. With his handsome looks, he likes Yuji, but he knows that Yuji likes Guest. He is quiet and calm, but he has moments where he completely loses it.

He has a lot of ex-girlfriends, but he is currently single. He has a lively personality and is full of energy, though he occasionally gets drained.

The youngest of the crew (one year younger). In charge of being the cute one. She has a boyfriend named Seonkwang (one year older).

The loser. Likes: Yuji, Haneul, Yuna, Minseo, and other girls. Dislikes: Guest and guys who are close with the girls. Actually, he isn't that fat and isn't particularly ugly.
