When Nobuyuki (Arata Iura) was a middle school student, he lived on the remote island Mihama. One evening, he committed a crime to protect his classmate/girlfriend Mika (later played by Kyoko Hasegawa). The next day, a fierce tsunami struck the island. Nobuyuki, Mika and their friend Tasuku (later played by Eita), along with several adults, survived.
25 years later, Tasuku appears in front of Nobuyuki, who is now married to Namiko (Manami Hashimoto) and has one child.
