Sayuri Haruno dreams of becoming a patissier, and for this purpose, she enters the elite Fleurir Confectionery School. Her classmates are a rowdy bunch, some of whom she quickly befriends and others who look down on her for being admitted on a scholarship. Standing apart from the rest of the crowd, Ryou Kouzuki is one of her few male peers, and he already seems to despise the noisy girls he will be studying alongside.

When the instructors are introduced, it becomes apparent why most of the students at Fleurir are female. Mitsuki Aoi, Gilbert Hanafusa, and Yoshinosuke Suzumi are beautiful men who are as skilled as they are popular. Sayuri is partnered with Ryou in an exercise to create a Western dessert of their choice; however, his overabundant self-confidence does not allow room for her own contributions. While she believes in making sweets to produce smiles in those who eat them, he is solely determined to win this informal competition and prove his worth. Will their finished product succeed in capturing the approval of the judges, Aoi in particular?
