"Women say that wearing sexy underwear makes them look more attractive and beautiful...so mothers should try wearing it once in a while." Her mother, Shuri, who forgot to dress up as a woman who only has her plain clothes and plain underwear, secretly tried on her while being confused. She didn't show it to anyone, but seeing her own obscene reflection in her mirror filled her with a sense of elation. However, she was witnessed through the gap in her window by the manager of the part-time store she happened to visit.
