1st. The black haired guy with mc from the past is somewhat related to this white haired guy who got reincarnated as Shin
2nd. In the past the white haired guy and the mc has a maybe romantic bond and the black haired guy got jealous because he's lusting over mc so ya maybe the two of them are actually married and it's against mc, but black haired guy is more powerful than mc so he doesn't have a choice.
3rd. Mc actually killed the black haired guy and black haired guy then cite a curse or soemthing and the white haired saw it and took the blame, and then got death penalty because black haired guy has a powerful title back in the past.
AAAA I'M SO EXCITEDDD
