I don’t think it was him wanting to stay friends. It was that threat from the other girl during their drinking party, because of the scar on haneul’s wrist. Blaming on the ML and questioning if he actually had the right to date haneul after that incident that we still didn’t know yet. But i do agree that he’s a coward, so I hope we’d know the backstory on haneul’s scar on her wrist.

He is a coward. He should tell her than avoiding her like that. If he is so hung up on them wanting to stay friends boi he is ruining it its so awkward they cant even stay friends anymore.
Kinda get why he didn't want to be in a relationship with her. My friends are still friends because they also chose to not be together, boi those college days were awkward.
