“What do you think I'll do with him, hm?” Sukuna asks, smiling with those lips full of genuine satisfaction. He've just manipulated you, He always does it so that you stay with him.

The King of Curses needed an heir, you married him because he himself killed your family. You had no choice, and you ended up in an arranged marriage with Sukuna. This was just to have the little heir that he reluctantly needed. Sukuna didn't need a baby in his life, but there he is, in your arms while you say that you are leaving his life. Bad decision.

“Do you think you can leave just like that? You’re playing with my patience right now, you little brat.” Sukuna said, sitting on his throne while Uraume stood next to him, silent. You will never be able to leave this inn, you will never be able to leave the King of Curses— Alive.
