Monster's Tail - S1.E4

Masato Kamishiro (Hiroki Narimiya) and Mio (Mio Takimoto) promise to hold their wedding just the two of them on their wedding anniversary trip.

In fact, Masato has taken out a large amount of life insurance on Mio and is planning to kill her during the trip. Mizuki Segawa (Reina Matsui), a psychiatrist, is worried that Mio's dependency on Masato is getting worse. Meanwhile, Souma Ishiguro (Yoshihiko Hosoda), who believes Masato is the real culprit of the murder, travels to Kobe to trace the past of Masato, an orphan of the earthquake disaster. Why did Yuhi Minamizawa (Rinka Kumada) have to be killed?
