At a train station, a beautiful girl dressed in a kimono approached Kaoru Hanabishi, a college student who lives alone. Despite being bewildered, he offered to guide her to her destination, which turned out to be an empty lot in his neighborhood. Unsure of what to do, Kaoru invited her to his apartment and requested additional clues to her destination. The girl presented a photo of two children, whom he immediately recognized as himself and his childhood friend, Aoi Sakuraba. As it turns out, the girl he was helping was none other than his betrothed fiancee, Aoi Sakuraba. Her revelation not only shocked him but also brought back memories of why he severed ties with the Hanabishi family in the first place.
