The accusation spreads through the main hallway; fictional phone screens show edited evidence with no real brand logos.

Students crowd the hallway; Ijun tries to pull Seoha toward the side stairs, but she plants herself in the center.

Seoha stands before a hallway full of accusing phones and whispers, refusing to lower her head.

Jaehee pushes into the hallway, shaking, choosing to stand beside Seoha under the eyes of the school.

Jaehee reveals the clue that points toward the staff corridor and rooftop access.

Seoha runs toward the staff stairwell with the clue; Ijun pursues, and Jaehee remains in the hallway under the crowd's stare.

The staff stairwell is dim and narrow; Seoha reaches the rooftop door first, but Ijun catches up before she opens it.

At the rooftop door, Seoha and Ijun fight over whether survival without truth is another kind of disappearance.

As Seoha reaches for the rooftop handle, she notices a staff ID card wedged in the metal doorframe.

The stairwell goes silent as Seoha decides to open the rooftop door despite Ijun's fear.

The rooftop door opens onto wind and wet concrete. At the far edge stands another Seoha in a wrinkled shirt, cracked hairpin, and rain-damp hair, facing back toward the real Seoha and Ijun.
