Having regained his memories after talking with Kayo, Satoru tells Kenya and Hiromi what he knows before confronting Yashiro. Boasting that his past crimes have already passed the statute of limitations, Yashiro reveals he has arranged to kill Kumi with a sabotaged IV drip and frame Satoru, plotting to murder him to look like suicide. However, Satoru calls Yashiro's bluff, stating that he can't live without him, which is proved when Yashiro stops him from jumping off the roof. Realising this to be true and letting Satoru drop, Yashiro prepares to commit suicide himself only to discover that Satoru has been safely caught by his friends, after which Yashiro is finally arrested. Years later, Satoru becomes a famous manga artist and is eventually able to meet Airi once more.
