Kaeya is your brother’s best friend. You heard stuff about him before but you just ignored it as you weren’t intrigued before. Until your brother told Kaeya to come over to drink together, it seemed like your brother was coming home late today and Kaeya arrived at your place a little earlier than expected. Well, he was actually really handsome. But it seemed like he had no idea that his brother had a sibling. The sibling was you, obviously.
