A man becomes obsessed with delusions due to his obsession with a woman he lost, and loses sight of reality. A girl he meets in a rundown entertainment district gently accepts the man's delusions. The only time the two, who seek each other as if to erase the boundary between self and other, feel reality is when they indulge in a dangerous game involving a time bomb... The audiovisual effects, calculated down to the smallest detail, such as the rain and humidity, the deliberate use of red in the color scheme, and the pop song the woman hums, contribute to the continuation of the conceptual story.
