Rain traps Yoon-seo and Do-hyun under the shoe-locker awning while students rush past in blurred umbrellas.

Do-hyun gives Yoon-seo the box as if returning a body. The cardboard is plain, worn, and not decorative.

Night. Yoon-seo sits on her bedroom floor with the shoebox under a desk lamp. The room is modern but plain, no real brands, only fictional stationery labels.

Yoon-seo reads the first letter by lamplight. Her reflection in the dark window overlays the paper.

The letter's gentleness becomes impossible to defend against. The room stays still while Yoon-seo loses control.

Morning after crying. Yoon-seo dresses for school with swollen eyes and the letter folded too carefully.

Yoon-seo finds Do-hyun on the school rooftop, where laundry lines and safety fencing make the sky look caged.

The rooftop wind lifts the letter edge. Do-hyun keeps his hands visible and empty, refusing to claim what was not his.

The wind breaks Yoon-seo's restraint. Do-hyun stands close enough to help and far enough to fail.

Do-hyun's body remembers comforting Yoon-ah before his mind can stop it.

The rooftop holds the shame of a gesture that belonged to the dead and landed on the living.
