The film features Nagano as the lead character Yosano Suzume, a senior high school student who transfers from the suburbs to a school in Tokyo because her parents are working overseas and she moves to stay with her uncle. Although Suzume has never fallen in love with anyone, she experiences her first love when she gets caught in a love triangle with her form teacher Shishio Satsuki played by Miura Shohei and her classmate Mamura Daiki played by GENERATIONS' Shirahama Alan.
Filming began at Inokashira Park on 7 October which happened to be near Kichijoji where Nagano was scouted so she felt that it was such a coincidence for the filming to begin here. As for taking on her first leading role in a movie, she commented that she does feel worried but is confident that things will go well with Miura and Shirahama around. Miura who is playing a teacher involved in a forbidden romantic relationship with his student commented that he will try to preserve the feel from the manga and do his best to play this character. As for Shirahama, he lost 5kg for the filming and hopes to be able to convey the importance of love through his performance.
