So his wife was going to marry another man and commit suicide afterward, the MC been missing (also thought to be dead, previously threw his life away) for over a year returns and prevents it, then MC marries her, MC supposedly feels guilty, he has to later leave for a tournament, promises his wife to return in about 2 to 3 months.
After that tournament the MC gets into a situation were he has only one means to escape but instead of using it to save himself he give it to someone else (what about your wife ?, what about your family ?, don't you want to protect them ?, doesn't your wife need you, don't you care about her, didn't you promise her that you'll return ?) to let them escape. MC waiting for death again thinks about the people he supposedly wants to protect. MC is thought to be dead for around three years, while his wife is all alone, in bad health and depressed. LOLOLOL this MC is a clown.
He is later ruthless to both enemy and family - he kills his own wife
MC becomes crazy, cruel and heartless and he even badly beat up his wife in public
