Oh gosh hahahaha (≧∀≦)
To be fair, he had always had a thing for the seme (since high school.) It wasn’t sex that made him stay.
Gurl I'm talking about back in high school too. You know.. that bit where he shoves his dick forcibly in the ukes mouth without consent? That bit or was it the rape after that? I forget. If I remember correctly he actually says that back in high school he though he might of had feeling because that was his first sexual experience. I could be wrong but I'm not rereading to prove this point lmaoo.
He had a thing for the seme before the sexual experience. He was always looking at him and getting angry because he was always with girls.
Kohai: Notice me senpia! *rapes* *blackmails* *treats senpai like trash*
-meanwhile-
Senpai:*into it* Oh yeah, you're an asshole but you're pretty/ possibly good at sex which means I'm in love!! (╯°Д °)╯╧╧
