Matsumoto plays the role of a senior high school teacher Hayama Takashi while Arimura plays his student Kudo Izumi. Due to their relationship, Izumi had to suppress her feelings for Hayama although she had been holding a torch for him. Years later when Izumi is an university student, she is asked to go back to the acting club of her senior high school to help out and reunites with Hayama which marks the beginning of their forbidden romance. Although Matsumoto and Arimura had worked together in the drama "Shitsuren Chocolatier" before as siblings, this is the first time that they are collaborating in a movie where they will have to take on intimate scenes.
Yukisada said that since he read the novel 10 years ago, he has been eager to adapt it into a movie. As such, he is happy to be able to get Matsumoto and Arimura to play the lead characters who are wavering in love and hopes to make this film into a signature romance movie. Matsumoto commented that although people may have different feelings and approaches regarding love, he believes that the moment when people's hearts are moved by others is something which everyone can identify with so he hopes to present the heart-wrenching love story to the audience with his co-star. As for Arimura, she believes that it will be an exciting experience for her this summer as she is filming in a new place and hopes to be able to convey the wholehearted love a woman feels for a man through this movie.
