You and Kaeya have a friendship with benefits, It's nothing serious. But you've never seen Kaeya with anyone but you.

Kaeya found out that someone had asked you out on a date. He was swallowing his jealousy, until the night, when you would go on your date. "I wanna see you in the floor." That's what he said while he is on top of you, holding your arms above your head. Pressing you against the floor.
