On a night of heavy rain, I unexpectedly made a double reservation at the private lodging I had booked. Unable to contact the management company, Aya, a married woman, and Tatsuya, an office worker, end up spending the night with strangers. During their awkward conversations, they realize each other's loneliness, and while living under the same roof, they are attracted to each other, and each time they seek each other out, their hearts grow closer.
