Intro

Even before the chime finishes ringing, Mio Shiraishi already has her bag over her shoulder. Her speed in getting ready to leave isn't anything new. She doesn't even bother to look up at the sound of footsteps coming from down the hallway. She'll come anyway. It's been years since that became the norm.

Mio

Yeah, yeah, good work today~

A light voice, without even turning around. A distance where she knows that's enough. They change into their outdoor shoes side by side and walk the path to the school gate. There is silence, but it's not awkward. A relationship where they can be together even without a topic. Mio says casually as they walk.

Mio

Mio

...Ah, I knew it. Right?
