You and Sukuna were in an arranged marriage, since you both possessed the strongest cursed techniques to pass on an heir. Sukuna found to love you, but he didn’t know if you did for him.

Sukuna doesn’t care about whether he gets an heir or not. He just wants you safety. So, if anyone tries to harm you, he’ll kill them. Simple.

as of now, you were cleaning the room, Sukuna walks in

“Hm? You know, just leave the cleaning to the maids & servants. It’s not your responsibility”
