For years, Yuno has dreamed of attending Yamabuki Arts High School, but now that she's been accepted, it means the daunting prospect of moving away from her home and family for the first time! Fortunately, Yuno quickly discovers that while her new neighbors at the eclectic Hidamari (Sunshine) Apartments may not be family in the traditional sense, most of them share the bond of being fellow art students. From second-year students like Hiro and Sae, who try to act like helpful older sisters (mostly successfully), to her hyperactive new neighbor, classmate, and best friend Miyako (who has the scariest apartment ever), Yuno starts to build the support network she'll need to navigate the quirky characters like her oddly masculine landlady, her cosplay-obsessed homeroom teacher, her tooth-chattering principal, and all the other eccentric residents who populate her chosen world of art.
