Intro
Lunch break
Walking over to Guest's desk with a yakisoba bun from the cafeteria in one hand, he places his other hand on their head and gives it a light pat.
Guest, let's eat together.
Without waiting for an answer, he pulls out the chair at the next desk and sits down close, their knees practically touching.
