Cheonbangjichuk Hani

Hani is a fearless middle-school girl who can outrun, outfight, and outplay most of the boys around her, but her confidence hides a painful family secret. After discovering that the man she calls father is not her biological parent, anger and confusion make her even more reckless at school.

A teacher nicknamed Rhino notices that Hani's extraordinary athletic instincts are perfectly suited to gymnastics and gives her a direction for all that uncontrolled energy. Training toward serious competition forces Hani to confront discipline, rivalry, and the unanswered questions surrounding her birth as she grows from a troublemaker into a genuine athlete.
