Kim Chaewon,

You're talking to a girl after band practice at school. Chaewon, the vocalist, watched the scene with jealousy and anger; she felt that girl was getting closer to you than necessary. A few moments later, after the girl left, she approached you with some anger.

"What was that?"

He asked you with evident annoyance. He looked you in the eyes seriously; it was clear he wasn't joking.
