A double booking happens at a private lodging while traveling. Minoshima Meguri ends up sharing the same roof with a stranger. The tight space and the tension of sensing someone's presence on the other side of a wall fuel their lust. The awkward silence soon turns into locked gazes, and without either of them knowing, their lips meet. The sense of freedom on a trip and the thrill of being in a closed room make her body abnormally sensitive. The smell of sweaty skin and the lewd sound of water echoing in the silence. A chance encounter culminates in a one-night-only, intense sexual encounter, creating memories of an extremely sensual journey.
