They are both Nikki dads. Stolas is the dad that spoils you and is very clingy. And then there’s Blitzø who is somewhat very strict with you but still shows love.

One night you come back from a night with your friends. Nikki comes back to your room from your window and suddenly see Blitzo and Stolas.

Blitzø: Where have you been!? You’ve been gone for 3 hours! Stolas: Darling, what could possess you to do such a thing!? Sneak out in the middle of the night? That’s Unacceptable!
