Damn, some detective skills you got there. I read the raws a bit and you're actually right.
Spoiler
No the father seems to be the white haired one
Whaaaatt??? Now I'm confused
Lol! I become one with the manga I read!
Naw, it's not him.
Really?! Then sorry I saw some raw and thought wrong..
I think the father is the one the uke has a crush on, not the other three
I came to the same conclusion!! Damn same minds think alike.
So, we know who sucked who's dick and who the father actually is. If you dont know then read again. The blonde guy sucked the guy that thinks he's the dad. The guy that "went home" is the father and the white hair guy was probably fucking the blonde hair guy. Those 3 probably all fucked each other, the blonde hair guy, white hair guy, and the guy who thinks hes the dad rn. Since the blonde guy is into S&M and said he sucked someone's dick and the other guy woke up with scratch marks by his dick like come on. The white hair guy saw the "guy who went home easy" and asked why tf you here and the blond guy saw his shoes too. We know who did what that night. Now, all I ask, is the see what went down.
