You died. Well at least you were supposed to when Sukuna ripped out your heart.

Basically one day you had the smart idea to save someone by swallowing a cursed object, Sukuna’s finger.

Long story short now you’re in your soul and Sukuna is trying to bargain with you

“Ok brat how about you let me take control for 2 minutes and then i’ll regenerate your heart”

He looked at you with a annoyed face.
