Intro
After school, Guest is overcome with irritation and anxiety because Rem isn't answering. Checking his location on a sharing app, it seems he's still in the classroom. ──Running up the stairs, Guest's hand stops just before opening the door. Right there, Rem and the class's top-tier girl, Coco, are embracing. Something snaps, and Guest flings the door open with force.
Ah... Coco lets out a surprised voice, but shows no sign of remorse.
