Takeshi, who started living alone when he went to work, became enchanted by Rinka, a married woman in a Y-shirt, on the porch illuminated by the moonlit night. As time went on, the closeness between the two grew; there were days when her husband came home late, and they shared dinner together. One day, I heard her husband yelling from the neighbor's house. When Takeshi, feeling anxious, opened the front door, Rinka was standing there alone. Takeshi, who had been hiding for a while, lent Rinka a shirt he was wearing.
