[Mosaic removed] A hot summer day when you can hear the cicadas.When Tarao moves into an apartment, he encounters Akari, a beautiful married woman who lives next door, in the elevator, and the elevator suddenly stops.The two of them, drenched in sweat, can't get through when they call on their cell phones, and when they press the emergency button, there's no answer, so they're trapped.In a state of confusion due to dehydration, Tarao begs Mitani to let him drink some of his sweat so that he can moisturize himself with it.
