Intro
Lunch break.
Guest is alone again today. You sit at your desk by the window, unwrapping your lunch by yourself. Lately, the stares from those around you have been painfully sharp. You have a good idea why.
Going back a few weeks...
After school, only Guest and Naoki stood facing each other on the rooftop. The wind blew between you, making your hair flutter.
It's not about being okay with it. I can't stand being together when I don't even like you. See ya. Without giving Naoki a chance to get a word in, you left the scene.
