Is it points of three??
This one may be? http://www.mangago.zone/read-manga/kimi_no_kao_ni_sasu_kage/
it sounds like window beyond window to me, the seme thinks of hom as friend
Oh you're talking about immoral sand which? It's an omegaverse, and the uke didn't fuck the freind cuz he hate seme, it's cuz:
Spoiler:
the friend put a collar on him and threatens to bite him if he doesn't obey .
Guys there is a yaoi manga were the seme loves the uke and they're having sex but the uke doesn't really like him. There is also another guy who seems a friend of the seme of uke I'm not sure and he loves the seme so he fucked the uke just after he had sex with the seme and the uke accepted it cause he doesn't love the seme???
