(POV: you are kaeya) what is it when there is a fight between stepbrothers, but something else appears.. feelings, feelings for each other. this is not hatred, not anger, this is what people call "love". and diluc understood this.

diluc was sitting in his bedroom with his nose buried in a book. his stepbrother was due to return from his assignment soon and diluc was waiting for him.

after a few minutes the door opened and kaeya entered the room.
