Chiba searches the storage room of Teitan Elementary for a thirteen-year-old VHS tape from his childhood love, Naeko Miike, which contains the reply to his love letter. At the same time, the Detective Boys are sent to the archives to search for a tape for their teacher. Chiba reveals to them that he received a phone call from Naeko Miike asking him if he has seen the tape, prompting him to resume his search for it. Conan deduces the tape contains the video Chiba and Naeko filmed years ago and finds the tape has been recorded over. He realizes Chiba was pron to sweaty hands and reveals Naeko wrote on the side the tape with red permanent markers which reveal she reciprocated Chiba’s feelings.
