Kokoa Hoto is a happy and lively girl who can make friends with anyone in three seconds. She befriends the quiet and brilliant granddaughter of Bunny House cafe's founder, Chino Kafuu, who is typically seen with the talking rabbit, Tippy, on her head, after moving live with the Kafuu family to attend high school away from home. Kokoa befriends another part-timer, Rize Tedeza, who has unusual behavior and significant physical abilities due to her military upbringing; Chiya Ujimatsu, a waitress from a rival cafe who does everything at her own pace; and Sharo Kirima, another waitress at a different cafe who has the air of a noblewoman despite her military upbringing.
