Your question reminded me of a yaoi I read a long time ago about a group of high school friends. One likes the one w/ a gf, and the other likes the other friend. In the end the one that liked his straight friend falls for his other friend who liked him. I can't remember the name or author though, but I think it fits what you are looking for.
Does anyone possibly know which manga this can be?
As a hint, there's a scene where they go for karaoke and their straight friend leaves in the middle of their session cuz he has to work and the other kid kisses the other friend and confesses.
Looking for yaoi manga, where mc likes someone (or so he thinks?) , but ends up with someone else (other friend who likes him?). It's not any particular manga, just looking for a scheme like this. Or something unexpecting when the reader don't know who will the mc end up with. Like the manga "smells like green spirit". Only completed. Thanks! ^^
