I’m searching for a yaoi that was so good, but weird af as well. It was on going.
I don’t remember it well, but it was an human with black hair and a demon with white hair. Then, the human was going to kill himself or something like that because everyone was thinking he was weird or something like that. Then the demon and the human did some WEIRD lewd things. And then the demon took the human to the demon’s world
I think there was a scene where we were seeing the « future » of those two, and in that future the human became much stronger than the demon (the human became a demon I think, but dude it’s been a while)
