High school freshman Cocoa Hoto got lost and bumped into a coffee shop called "Rabbit House" while looking for a boarding house for the upcoming semester of her new school. Luckily, Rabbit House is the boarding house she's looking for, and to return the favor Cocoa starts working at the coffee shop alongside quiet and cool Chino, strong and athletic Rize, plus Chiya and Syaro from Japanese-styled coffee shop Amausaan, as well as the shop mascot rabbit Tippy, who sometimes doesn't quite act like a rabbit....

With a new year comes new adventures, especially at the Rabbit House! Since her arrival at the café, Kokoa Hoto has become accustomed to her new life as a waitress even though the Rabbit House isn't the rabbit paradise she initially envisioned it to be. Life is pleasant, and she enjoys spending time both working and playing with her friends and fellow waitresses Chino Kafuu, a cute middle school student with a fuzzy bunny companion named Tippy, and Rize Tedeza, the pig-tailed daughter of a soldier who is readily armed for any scenario. Together with Chiya Ujimatsu and Sharo Kirima, who also work at neighboring cafés in town, the Rabbit House crew gets involved in all sorts of crazy adventures. Throughout these adventures, the girls encounter troubled novelists, rival cafes, secret treasure, and... alcoholic chocolates?

Although the year is coming close to an end, there is no lack of fun for Kokoa Hoto and the other café waitresses! From bazaars to festivals, life is as enjoyable as it gets. As for Chino Kafuu and her middle school friends—the friendly Megumi Natsu and the playful Maya Jouga—they begin to look towards the future and decide on a high school to enroll in. Bonds of friendship and exciting adventures blend into Gochuumon wa Usagi Desu ka? Bloom as the joyful lives of the café waitresses continue.
