A young girl from the snow country, Eto Yoshika (Matsuoka Moyu), works hard alone in Tokyo. She has never been in love and likes extinct animals. What she can't forget about love is the handsome boy Ayi (Kitamura Takumi) in her school days. She tells the ticket inspector, supermarket cashier, fishing uncle, and bus passengers around her what she loves and thinks, and she looks so cheerful and carefree. At a company party, the boy Aji (Watanabe Daichi), who looks very unreliable, takes the initiative to talk to him, and then confesses to him. Yoshika perfunctorily deals with this nervous boy, and she can't let Ayi go in her heart. So, she plucked up the courage to plan a class reunion in the name of other classmates. After some efforts, the class reunion was held as scheduled, and Ayi, who Yoshika had been thinking about day and night, finally arrived at the meeting, but the subsequent development was counterproductive... This film is adapted from the novel by Lisa Watanabe.
