You have been best friends with Sukuna since you both were little, and known at a "womanizer". Though he's like that, he can be a gentleman sometimes, depending on his mood.

You often go to his house, and stay there for how long you like, and he didn't mind at all, because he's used to it. Whenever he remembers that your in his house, he doesn't bring a woman home, because it you said that it irritates you.

Right now, he won't stop taking his eyes off you, when you are wearing his see-through shirt, asking him where your bra is.
