So I've been having trouble recalling a certain yaoi I only read once years ago. It was about this guy, the uke (I'm pretty sure), who kept dating tons of different guys and then breaking up with them, very fast, because he was searching for his special someone. One of the guys he broke up with, the seme, really loved him and approached him again after awhile (I think at least a year had past) and he wanted revenge for the pain the uke had caused him. The uke didn't even remember the seme since he had dated so many guys. I vaguely remember the uke almost getting raped but then the seme saves him, I could be wrong but I'm pretty sure. In the end he ends up falling for the guy he broke up with years ago. I remember the uke being in college and the seme being a bit younger in age (at least a year younger) but these points I'm not 100% sure about.

Remembrance, a forsaken thing that revokes ignorance and leaves people in doubt, is my only redemption and solace deep within the cascade of white.

The evergreen trees speak of days long past when music mingled with the wind and sweet murmurs brushed our cheeks.

The setting is high school rather than college, but: Unmei no Anata by Yamakami Riyu, maybe?

Yes, that is it! Thanks!
