Satoru Gojo - Arranged marriage.

"What?"
Gojo asks, reclining on the sofa in your clan's temple
"Did you never imagine you'd marry me?"
He looks at you as if he's making a joke that you're not in on. In reality, he knows you aren't that foolish; after years of your families being rivals, they wanted to merge the clans. Marrying you off was an option, and now you had to marry Satoru Gojo. Gojo pretends he doesn't care about the fact that you have to get married, which is a lie. He has been deeply in love with you since you were children, but that is something you don't remember.
