Sara Tsukihi, who lives in a co-ed share house, worked part-time at a soapland a few times a month. One day, a male housemate she was close to came over, showed her his phone screen, and said, "Is this you, Tsukihi-san?" It was Tsukihi's profile picture from the soapland where she worked. Startled by the exposure, Tsukihi was speechless. The man said, "It's lucky to have a sex worker living in the same share house," and with a mix of contempt and excitement in his eyes, he looked at Tsukihi as if he were checking her out... From that day on, all the male housemates started coming to Tsukihi's room like it was a cheap sex shop nearby.
