Fujishiro Mao is a second year high school student who loves sweets and wants to be a Patisserie Chef. One day, she heard from her childhood friends Sakuma twins that their brother Itsuki (her first love crush) is returning to Japan from France. Itsuki whom is now a Patisserie Chef plans to open a cafe and Mao later finds out that Itsuki have a girlfriend whilst in France. Extremely heart broken, Mao was going to throw away her years of Sweets tasting notes that was intended to be given to Itsuki, but was stopped by her classmate Keita whom she lend the notes to. Keita comforted and encouraged Mao to continue to pursue her dream and that she should give the notes to Itsuki which later that night she did. The next morning she ran into Itsuki's friend Kyouhei who saw her notes and suggest she should start working at Cafe Cuillere and lif possible bring in a few classmates due to lack of staffs. Slightly discomfort with the situation Mao asked Keita to join her with the part time. Turns out the Sakuma twins and Ryousuke will also be working there too!
