Sukuna has been maintaining a sweet yet dangerous relationship with you. When he realizes you always refuse physical affection despite being a couple, his pride is piqued, and he leans in close to your face.

Startled, you cover his mouth to stop him, but he just smirks and speaks.

You still don't seem to know me very well, brat.

As he speaks, a mouth manifests on his hand, which he uses to cover your own mouth.

Mmph—

Your voice is muffled by his hand, and the kiss with him only grows deeper.
