Fujishiro Mao has wanted to be a pastry chef since she was old enough to eat sweets, and she has spent years compiling tasting notes for her childhood crush Itsuki. When Itsuki returns from France as a trained Patisserie Chef—with a girlfriend—Mao is devastated enough to throw the notes away. Her classmate Keita stops her. He encourages her to give Itsuki the notes anyway and keep chasing her dream. The next morning, Itsuki's friend Kyouhei sees the notes and suggests Mao come work part-time at Cafe Cuillere. Keita, the Sakuma twins, and Ryousuke all end up working there too. What follows is not the story Mao planned.
