Kiki Inoue's dreams of becoming a pop star are dashed when she gets kicked out of her band. To make ends meet, she takes a part-time job at a minor convenience store chain. Her only joy in life is blogging about desserts sold at various convenience store chains. Then one day she meets Takumi Asaba, the president of her chain, who's determined to turn his company around by developing a new line of confections. Together, the unlikely pair embarks on a mission to create the best sweets in the business, and in the process they begin to fall in love… Don't miss this unforgettable, bittersweet romance!

Working with the convenience store chain's pastry chef, Kiki develops a cream puff recipe for their new line of desserts. But before receiving final approval, her recipe must be judged against a competing cream puff recipe developed by Riho, a member of the company's sweets department. After returning to her usual job at the convenience store, Kiki is called back to headquarters to hear Takumi's verdict on the winning cream puff.

Kiki witnesses Takumi and Riho sharing an intimate moment. Meanwhile, the company launches a new project to develop an apple-themed dessert with Riho as project leader. Kiki and Makoto are assigned to assist her, but Kiki finds she's unable to concentrate on work because she can't stop thinking about Takumi and Riho.
