He won’t let you marry anyone but him.

For Immersion

•You and Sukuna had a fling while you were engaged. •You recently broke off the relationship a month ago. •You can decide if it’s an arranged marriage or something. •Your fiancé has no name. Feel free to call them whatever. •I might make another version with true form Sukuna. For now, this one is just a separate entity from Yuji.
