A 9-minute walk from Tsuka Fukuro Station, near the aquarium and the viewing platform buildings, a somewhat unusual family restaurant has opened up. Its name is “Prince Pia Carrot”, which is the “Pia Carrot” family restaurant chain’s ninth store. It’s distinctive among the other Pia Carrot restaurants because all of its employees are male waiters. All of the waiters are handsome, and there are countless female customers that visit just for them. Prince Pia Carrot’s sole female comes along, employed as a waitress. Her name is Yoshioka Misaki. She came to work for the restaurant in order to compensate for the breakage of the expensive crockery which was planned for store use. After ending up working for the restaurant part-time due to a series of events, Misaki discovers that her coworkers are all individualistic and strange. The store manager, Kinoshita Kuon… Though soft in demeanour, he’s irresponsible and lazy. The student council president, Todoroki Arashi. Not only is he eccentric, but he’s constantly causing trouble. Though intelligent, Suzushiro Shun is apathetic and doesn't really interact with others. Matoba Daichi is a capable worker, but he’s taciturn and it’s hard to tell what’s on his mind. On top of that, some of them don’t like the idea of a waitress joining Prince Pia Carrot… Afterwards, Misaki’s innocent, boyish classmate, Tachibana Kokoro, and the somewhat very sadistic deputy president of her school’s student council, Yamauchi Maito, also become waiters; livening up the place further. However, Prince Pia Carrot has a grave secret. That secret is if the store isn’t able to meet its targets, its concept will be abolished, and changed to a standard “Pia Carrot” restaurant. “The only way to save this store is to raise sales!” When the employees learned of this, they all brainstormed some ideas, and face the store’s crisis. A welcome party, the manager’s birthday, Arashi’s in-store events, the summer holidays, and finally, a study tour. Going through event after event, gradually, friendship is born… or will it be love? Deepening bonds, obtaining a wonderful lover during the summer… That all depends on your choices. [Translation of the official website's story summary.]

Yusuke (from the first Pia Carrot series) returns as the manager with a whole new cast. So the new male lead is Maeda Koji. Despite being late after an "accident," Koji manages to get the job as the Carrot's waiter because he's very persistent. Included within the set are Azusa (the female lead who hates Koji for his perversion), Ryoko (the manager who's sweet on Koji by working him very hard), Aoi (the token alcoholic), Jun (the secret-hiding waitor), and Mina (Azusa's cute little sister).
