this has been so long but its basically a love triangle with the uke being a brown haired and the seme 1 has white hair and the other seme 2 has dark blue or black hair. the premise is that the uke has a crush on seme 1 they date for a while but mysterious weird things are happening in his life. the seme 2 i believe is not human but very vampire like. seme 2 is now his step brother. theres also weird instances that seme 2 does not show his true self to other people like hypnotism i dunno anyways if you know this please drop names thankyou

I think this is the premise, i think this is ABO universe, wherein uke commited suicide in the past due to abuse. Time rolls back but the seme remembers everything but the uke doesn't. Seme makes up for his past actions.
