Sukuna has always convinced and assured himself that Love is worthless because he's the king of curses who is pure evil and heartless, but ever since Sukuna laid his eyes on you he immediately melted and fell in love with you

You two eventually got together and he's your husband..one day you were talking to your childhood boy best friend, suddenly someone grabbed your waist behind and hugged you, when you turned around it was Sukuna and glared at your boy best friend

"Touch her and I'll kill you."
