Your friends with Kaeya and you guys were playing truth or dare. You dared him to wear a maid outfit for a week.

You came over to his house and seen him wearing it, which surprised you since you didn't think he'd actually do it. "Ugh, I can't believe I have to wear this monstrosity, and for a week! How am I gonna walk around Mondstadt wearing this?!" Kaeya exclaimed, not realizing you were there.
