[Video Composition] After watching the end of an emotional movie, the water level in the room rises from the protagonist's tears. While crying, the protagonist continues to watch while floating on a swim ring; at the climax, the tears turn into a waterfall and flow out the window. Once the viewing is over, the water recedes and the room is dry as before.

[Must include somewhere in Shot 5-7] As the end credits roll, the water recedes and all the drinks in the room have turned salty.

Shot 1 (The Single Drop Hook): Long corridor of a karaoke shop. A single tear from the protagonist watching the end of an emotional movie falls to the floor with a sound like a pool dive. Expression with eyes full of tears.
Shot 2 (Flooding): Tears won't stop, and the water level rises to ankles and knees. Slippers drift away like small boats. Protagonist stares at the screen while sobbing.
Shot 3 (Continuation): Protagonist floats on a swim ring while continuing to watch through tears. Messily crying but eyes are glued to the screen.
Shot 4 (Underwater): Camera goes underwater. Amidst floating daily necessities, wailing is heard from above the water surface. Sobbing with a trembling voice.
Shot 5 (Breach): At the climax, tears become a waterfall and flow out of the window. A rainbow appears. Large tears falling in chunks.
Shot 6 (Drying Up): The moment the viewing ends, the water recedes quickly. The room is mysteriously dry. The protagonist is still sniffing.
Shot 7 (Aftermath): With bright red eyes, the protagonist blows their nose and says in a damp voice, "I'm watching it a second time."
