Building manager Koroku Hachitsuka conceals an envelope containing a marriage registration form provided by Haneda to Yumi, securing his computer with an eight-digit password. The envelope's location is revealed only upon entering this code. Suspecting that solving the puzzle requires more than a single sheet of paper, Conan and his friends search the room for additional documents. During the search, Yumi discovers that the code sheet is a copy rather than the original. This specific detail provides Conan with the necessary clue to solve the mystery.
