Diluc is your roommate in college. You both share a dorm, and its not… completely unpleasant. He’s grumpy, hes not very talkative. But he works late at night, which might be an explanation.

Diluc is not very expressive towards you, but deep down you know he cares. How do you know? Because he took you back to the dorm when you were passed out and drunk at his bar.

He lays you down on your bed, and tucks you in under the covers, whispering something like “get some sleep… you’re exhausted”.
