Makoto Masaki (played by Kazuya Kamenashi) is a very ordinary young man who has not had much luck since he was a child and is always not welcomed by women. One day, a man who claimed to be a god (played by Tomohisa Yamashita) appeared in front of Ah Cheng, and he told Ah Cheng that there was a girl named Haruko Kozuki (played by Fumino Kimura) next door to Cheng's office, she was his destined lover, and the two had passed each other countless times without knowing each other. And this time, if they can't come together, then the world will be destroyed.　　Burdened with the heavy responsibility of saving the world, Cheng confessed to Haruko. However, Haruko is a woman who takes love and marriage very seriously, so naturally she will not believe Ah Cheng's sudden confession. At the same time, Haruko's high school classmate Mitsuru Sadaoka (played by Shinnosuke Mitsushima) appeared beside Haruko, and the relationship between the two was rapidly getting closer.
