Shuhei admires his new wife, Risa (Sakamoto), who lives across the street. Every morning I look through the window at Risa as she sends her husband off, hoping to get closer to her. However, Shuhei had a mystery about Risa. It is a shady man who visits Risa's house every Wednesday. When he comes, the curtains of the room are closed all at once. Shuhei wondered what was happening in the room and decided to ask him directly. I was taken aback by the true nature of Risa when I saw it for the first time.
