It’s almost the summer holidays.
The protagonist, Houkou Hayao, decides that he wants a part time job, and accepts a job interview at the family restaurant, Berry’s.
On the same day as the job interview, Hayao has a chance meeting with a certain young lady. That young lady- whose shoulders were trembling in fury- bursts out of the job interview room, and binge eats at Berry’s. She drags him around and he ended up hanging around with her for a while, but he never found out what made her so upset. On top of that, when he gets home, he finds out that his younger sister, Yuuka, has found out that he got a job without permission.
On the day of the job, he learns that there is another new employee. It turns out to be the binge-eating girl he met on the day of his interview, and she is introduced as Morikubo Yuna.
A variety of other unique co-workers come to introduce themselves. The petite twins, Satou Haruki and Natsuki. There’s Makinosawa Ena, though younger, is fine with bantering and teasing Hayao. Then there’s the athletic and energetic Izuno Youko. That is the start of Hayao’s hectic, but fun work life.
The summer holidays is just around the corner.
Surrounded by gorgeous girls in uniform, so begins Hayao’s summer story.
