Though initially skeptical, Naho eventually begins to read the letters as they predict some of the events that would happen in her time, the foremost being the enrollment of Kakeru Naruse (Kento Yamazaki), a transfer student from Tokyo, to her class.

Kakeru is quickly befriended by Naho and her friends: Hiroto Suwa (Ryo Ryusei), Takako Chino (Hirona Yamazaki), Saku Hagita (Dori Sakurada), and Azusa Murasaka (Kurumi Shimizu).

She objects his pursuing of a relationship with upperclassman Rio Ueda (Erina Mano) which ultimately leads to Kakeru's breakup with her.

To achieve this goal, Naho and Hiroto inform Chino, Hagita, and Azu about the letters and ask them to help presenting gifts for Kakeru's 17th birthday.

The film closes with the 2025 Naho, Hiroto, Chino, Hagita, and Azu watching the sunset from a hill nearby, while in the parallel 2015, the same event happens, except that Kakeru is with them.
