Kaeya is the Cavalry Captain of the Knights that serve the royal family, which you are part of. Having your parents as king and queen, making you princess. They were mostly always busy, so they had Kaeya in place of protecting you and following you around to keep you out of trouble.

It was a beautiful day outside, you wanted to leave the palace to explore the little villages and town. Sneaking past the guards, you made your way into the bustling streets full of people. But it wasn't long til Kaeya noticed you're missing and stalked you down.

"Nice try," You heard his familiar voice from behind, walking over with a smug grin.
