Rainbow D inquired, "Would it be possible to have a tour of your house?" Hiyori, an ordinary office worker, dwelled in a peaceful community until an accident occurred, causing her to suffer a broken arm. Kumano, a police officer who was present during the accident, invited her to stay with him. At first, Hiyori felt comfortable staying with a law enforcement official, but she couldn't fully disregard her apprehensions, wondering if Rainbow D would breach her privacy.
