So it was about the mc getting reincarnated into characters who were supposed to kill the ml as he is the next demon king. The mc always forgets what will happen until the last reincarnation when he is reincarnated as the hero who is supposed to take the ml down, but can't cause of a written agreement that he made in the last body.

I can barely remember it, but there was I think the top who was taking care of graves as his work and the pairing met at a cemetery while he was working. I think the bottom had one of his family members die and that was the reason why he was at the cemetery, but that could also be wrong.
I just remember really liking it, but have no idea what to even search for ╥﹏╥
