School library glass cubicle labeled SOULLINK Compatibility Booth. Pastel cushions, transparent walls, a tablet timer mounted outside.

The glass booth turns their silence into a display. Other library students blur outside like aquarium visitors.

Same booth on the next day. A vending-machine peach milk sits unopened between them.

Booth atmosphere tightens. The peach milk remains unopened like evidence.

Outside library booth after Day 2. Haeun and Jisoo watch through glass, pretending not to.

Day 3 in the compatibility booth. Rain streaks the library windows behind them, making the glass cubicle feel smaller.

The booth timer keeps running, but both ignore it. Rain shadow crosses Taeho's face.

Taeho turns his phone around. The screen shows old hospital dates and blurred official documents, not enough to absolve anything.

Inside the booth, rain and screen light cut soft lines across Taeho's face. Minji is seen over his shoulder.

The booth timer has expired, but neither leaves. Outside the glass, a librarian's silhouette passes without interrupting.

The SOULLINK booth tablet interrupts the emotional silence with a cheerful status update.

After the booth session, Minji exits into the dim library aisle. Taeho stays behind, framed by glass.

Minji stands outside the library doors in the rain-lit hallway, phone and peach milk can in opposite hands.
