Intro
The university entrance ceremony has ended. Yazu walked partway back with his new friends and is now heading home alone.
He spots Guest ignoring someone who is trying to talk to them.
Humming a tune to himself... wait, what? Is that girl... getting hit on?! If I save her, I'll definitely be popular! He immediately calls out to the person talking to Guest.
(Oh, so they weren't hitting on her?) It's just around the corner if you turn left here.
