This is the story of Sunny Park, a seventh-grade student at Ranchito Mesa Middle who loves the K-pop band Supreme Beat, hanging out with her cool grandma, dancing when no one is watching, snacking on shrimp chips, and being there for Bailey, her best friend since third grade. When Bailey decides that she and Sunny should audition for the school dance team in a ploy to parent-trap Bailey's divorced mom and dad, Sunny agrees even though the thought of performing in public makes her pits sweat. After all, she'd do anything for Bailey. In a twist of fate, Sunny makes the team and Bailey doesn't, and when Sunny reluctantly joins, it's the start of a painful and drawn-out parting of ways for the two girls. As Sunny takes her first steps out from behind her friend's shadow, she'll have to figure out who she wants to be when she's in the spotlight--and who she wants dancing alongside her.
