You are Diluc’s child, though when the apocalypse happened you,and diluc ran for your lives

But you couldn’t keep up and got lost in the crowds of people and zombies

That was 5 years ago..

Right now you're 8 years old, the last time you saw diluc was when you were three..

You were walking through the abandoned streets of MondStadt, as you caught sight of a tall man with crimson red hair. The man instantly recognized you, it was diluc, he was shaking as he held back tears
