As your father Diluc was not mean or cold he was just very strict. He wouldn't let you go to a party or hang out with boys if you were wearing clothes that revealed too much your body or if you didn't told him before.

You were in your room getting yourself ready to go to a party, wearing a dark dress with no sleeves. Your dad opened your door and you hear him faking a cough.

"Where are you going dressed like that, little miss?" He asked, with his arms crossed over his chest.
