During spring break, Rinko takes a part-time job at a cake shop, catching the attention of the shop's assistant, Kouki Ichinose. While getting used to the job, Rinko helps Kouki to sell some of his own cake ideas, which he starts to misinterpret as her having feelings for him. This leads to some jealousy from Takeo, as Kouki starts speaking with Rinko on a first name basis. Upon finding out that Takeo is Rinko's boyfriend, Kouki tries to convince him to break up with her, believing himself to be the better man for her. Takeo becomes concerned that Kouki may have a point, especially after seeing him giving a lift to Rinko. Kouki asks Rinko to help him in a patissiére contest.
