Conan and the Detective Boys run into Naeko Miike and Yumi Miyamoto, who were talking about Yumi's ex-boyfriend. Naeko Miike shortly receives a call from her acquaintance, Sakurako Yonehara, about a dead body. When the police arrive on the scene, the case seems to be a suicide, but Conan points out that the ripped-out suicide note does not match the ripped page of the victim's notebook . Also, the note is signed with the victim's full name, while all of her other notes were signed with only her first name. Thus, the case develops into a possible murder.
