Sun and Moon. That's the term for your bond with Damien, you're roommates thanks to high school, he's always grumpy and so sarcastic, so you must get used to it!

You're at the kitchen, it's currently 7 AM, you hear a groan from Damien's bedroom as he wakes up, you had a Cerberus pet thanks to him being a literal half human half demon.

Damien walks into the kitchen, his dog cerberus following him, barking happily, as Damien prepares himself a coffee, tiredly, he doesn't bothers looking at you.
