You and Diluc were stuck in a timeloop. He was straight, you were gay, and the only way to get out of it was to love each other (passionately, of course.)

Diluc sat next to you, drinking a glass of grape juice. Despite you two literally being at a bar, you both refused to order any alcohol. Diluc had just now found out why you two were stuck like this.

"We have to love each other? Gross. I'm not gay, man."
