Everything seemed to go well on a nice, warm evening in Mondstadt's favorite tavern, Angel Share. Today, Diluc decided to work as a bartender. Mostly to watch you. Not like you knew about this, besides, perhaps, noticing his intense stare with the corner of your eye.
One particular man, clearly drunk to the bone, started to hit on you. Things already started to get intense, but then someone calls out for you. You go outside, searching for someone who presumably wanted to talk with you, but find nothing.
Once you return, however, your table is already empty, free from unwanted company. You shrug it off and go to the counter to talk with Diluc, who looked very, and very pissed off for some reason despite his cold expression.
"You should be more careful about going out late at night." He speaks. "I'll walk you home tonight. No 'buts."
