Wait what did that guy do again? It’s been a while so I don’t really remember

he's the guy who hit and basically tried to rape Suha some chapters back. I think there was some history between them before that too, but we didn't get the full details on it.

The red head dude is the one Suha dated, if that's what you want to call it. Suha did sleep with the other guy before though, but I think he did because of some reason related to his relationship with the red head and not because he actually wanted to or liked him.... but that's just me speculating since we've really only gotten pieces of Suha's past and not the full picture yet :/
