While the rain poured heavily outside, Aya, a married woman, checked into a guesthouse she had booked. Suddenly, Tatsuya, an office worker who had also booked the same room for his business trip, appeared, causing a double booking. Unable to contact the management, these two strangers found themselves sharing the same room. During their meal from a convenience store, an awkward conversation began, gradually revealing their shared loneliness. Just then, the lights went out with a loud thunderclap. Tatsuya rushed to investigate a scream and discovered Aya naked in the bathtub, surrounded by steam. As they continued talking, he learned that her loneliness stemmed from her husband being abroad. Late one night, Aya found Tatsuya pleasuring himself while thinking about her, and the distance between them crumbled irreversibly—‘Do you think about me?’ What was supposed to be just one night turned into a passionate affair, and each time they met, they grew closer.
