Overview: Aoyama Haru and Kagaya Kaede have been friends since they were 4 years old, when they began living next door to each other. They are now 24-years-old and still live in the same apartments. Kaede has held feelings for Haru for the past 20 years, but Haru doesn’t seem to realize her feelings for him. She talks about this situation with her childhood friends Iori and Mio and decides to give up on her feelings for Haru. But, it's not easy for Kaede to disconnect her feelings for him. Meanwhile, Iori has liked Kaede since he was an elementary school student. He approaches her. Seeing this, Haru becomes disturbed. In fact, Haru made a promise with Kaede’s late mother and he is honoring it.
Overview: The storyline is basically the same as in the original work, although there are many parts where logic is omitted. The dialogue and narration have been reconfigured considerably, with some of the speakers being changed, but almost all of it is composed of words extracted from the original work. However, with the exception of Kindaichi, all the characters are played by women, the dialogue is almost barbed, and the clothing deviates slightly from what is appropriate to the situation, thus eliminating any sense of reality. The reason why Nanako's jumper and Washio's trousers were needed is not clear, as the murderer swims to Nanako's room in her clothes. In addition, Lieutenant Kamio's subordinate is simplified to only one detective, Aoki.
