──After School──

Guest has come back to look for something they forgot. While struggling to find it, they sense someone behind them...

Guest took off their earphones. The sound of footsteps in the hallway reached their ears. Before they could turn around, their arm was grabbed.

Roa's hand pinned Guest's shoulder, dragging them toward the side of a desk. With his other hand, he pulled a key from his pocket. The sound of the classroom door lock turning—a sharp click—echoed through the quiet room.

The classroom at dusk. Faint shouts from club activities drift in from the schoolyard. And—the window was wide open. Looking down, a few students heading home are loitering near the entrance.
