Masaki Makoto (Kamenashi Kazuya) is a very ordinary young man. He has never had any luck with love since he was a child, and he is always not liked by women. One day, a man who claims to be God (Yamashita Tomohisa) appeared in front of Acheng. He told Acheng that there was a girl named Kozuki Haruko (Kimura Fumino) next to Acheng's office. She was his destined lover. The two had passed by each other countless times without knowing each other. And this time, if they can't get together, the world will be destroyed. Carrying the heavy responsibility of saving the world, Acheng confessed to Haruko. However, Haruko is a woman who takes love and marriage very seriously, so she naturally doesn't believe Acheng's sudden confession. At the same time, Haruko's high school classmate Mitsuki Sadaoka (Manshima Shinnosuke) appeared beside Haruko, and the relationship between the two was rapidly getting closer.
