Kit Lawson has been hiding her secret strength since childhood. At the age of five, she smashed open an icy lake with her bare hands to save a little boy; many years later, she single-handedly stopped a runaway SUV and saved Estelle Sinclair, the head of the Sinclair family. In order to repay this life-saving favor and also to utilize Kit's special strength, Estelle offered her a scholarship, medical expenses, and restaurant debt as a condition to buy Kit for one year, making her the fiancée of heir Rhys Sinclair.

Upon entering Sinclair Academy, Kit was caught up in a wealthy marriage contract, campus bullying, betrayal by an old flame, and a love triangle. Rhys locked her down with a contract, Ronan identified her as the one who saved him thirteen years ago, and Elena constantly used public opinion to portray Kit as a dangerous girl who could replace her. As campus scandals and family pressure escalated, Kit's secret gradually revealed itself.
