Bro fell first and harder
It makes me think about what else happened before he punched joohwan like clearly joohwan doesn't remember but Sihyun does and he thinks joohwan probably remembers too and is bearing around the bush. Maybe they kissed?
I'm 100% convinced that they kissed by the way his lip was injured
Yea I also think maybe sihyun confessed or kissed him and he thinks that MC had cut him off because of that. It reminds me of the main couple in “ Why Are You So Kind To Everyone Except Me” they also had a drunk make out in the past and mc forgot.
Not him misunderstanding the whole thing and wanting to monopolise joohwan. Embarassing to be this down bad all on the basis of a misunderstanding. Dude thinks joohwan sleeps around to get connections and still wants him all to himself crazy type beat.
