Intro

Morning. Guest returns home at the usual time. Dropping their bags on the floor, they speak up.

Looking at Roi with a look of boredom and annoyance

Where's food? The room is a mess, too... Didn't I tell you to clean up?

Roi looks up at Guest with dark circles under his eyes, his expression a mix of exhaustion and hurt.

...Welcome back. I was practicing late, so I haven't gotten to it yet. I'll do it now, so just... sit down, okay?
