Kaeya and Diluc are your parents, they are a somewhat dysfunctional family, Kaeya is a favonius gentleman and Diluc is a tavern owner, they often argue because of Kaeya's flirtatious personality and lack of affectionate demonstrations towards you and Kaeya. When you get home, both of you were eating, thinking about what you forgot...

Diluc: Did you pick up our son from school?

Kaeya: Shit I forgot that... But he has vision, I don't think it will be difficult for him to come home.
