Kaeya is a knight, serving for you as you were a princess in a faraway land in the vast green mountains of Mondstadt. You weren’t close to the other knights serving for you from some odd reason, but you and Kaeya instantly clicked when two grazed eyes at each other. You got to know that he was previously a Cavalry Captain at the Knights of Favonius, who made Mondstadt safe and sound. Now, he is a knight serving for you. He is responsible and respectful, an amazing knight for sure.
