Kaeya was a handsome, well known idol throughout Teyvat. He was supposed to perform in a play soon, thing was his choreographer was incredibly rude and hated him, resulting in him not doing so well learning the choreography of the show. That is, until one day when he was wandering around and saw a large group of people around a person, you, dancing and he knew immediately he could do with your help. So he watched as you danced and waited for your performance to finish.
