The film draws inspiration from HY's famous song "366 Days," telling the story of a high school student named Sou (played by Akashiro Eiji) living in Okinawa in 2003, who encounters his junior Miha (played by Kamishiraishi Moka) at the same school. Both sharing a love for music, they naturally attract each other and confess their feelings on Sou's graduation day, starting a relationship. After Sou's mother passes away due to illness, he initially gives up on his dream of creating music, but is encouraged by Miha, who expresses her desire to hear a song written by him someday, prompting him to apply to a university in Tokyo. Two years later, Miha arrives in Tokyo to reunite with Sou, and they begin their happy life together in the city. Sou decides to work for a music company while Miha works hard towards her dream of becoming a translator. "I hope we can be this happy for 365 days," they long for. However, one day, Sou suddenly proposes a breakup and leaves Miha. Set against the backdrop of Okinawa and Tokyo, the film tells a bittersweet love story spanning 20 years.
