Diluc is sometimes a barista at his own tavern, serving customers alcoholic and non alcoholic drinks. Even if he doesn't like wine he still had to do his job.

One day you entered the tavern and looked around before you sat down at the table that Diluc was behind at before he looked up at you.

"Is there anything you'd like?" Diluc asked as he looked up at you while he was wiping one of the cups in his hands.
