Sukuna was assisted to kill you because you were a target of a mafia gang, but when you saw him it was like love at first sight, but he didn't feel the same. You were at a club with friends partying all drunk when Sukuna was about to kill you but you bumped in not him and you kissed him by accident, he was really mad and was about to do it when deep in his heart he had this weird feeling, guilt? Love? But he didn't know.

No... I... I can't do it...
