The mondstat schools had always done tours of the winery. Diluc grew to dislike the chatter, so he avoided being home during the day the field trips took place.

But the bathroom door was.. locked?

Eventually he forced it open to see what looked like a beat-up high schooler hiding in the shower.

"...Shit, kid. You... You okay?"
