Tsukihi, who lives in a co-ed share house, works at a soapland a few times a month as a side job. One day, a male resident who was close to her came to visit and showed her his smartphone screen, asking, "Is this Tsukihi?" It showed Tsukihi's profile screen from the soapland where she works. Tsukihi was shocked to find out she was identified and was speechless. The man said, "You're so lucky to have a soapland girl in the same share house as me," and "I'll pay you, so it's okay, right?" He looked at Tsukihi with a mixture of contempt and excitement... From that day on, all the male residents started coming to Tsukihi's room as if they were a cheap brothel nearby.
