Tori, a 200-pound girl, is mocked as "the whale" at school. Only Cole, the campus heartthrob, seems to treat her differently, without disdain. To win him, she diets desperately and nearly faints. She thinks Cole likes her—until she learns he only uses her for homework and secretly laughs at her. Heartbroken, she discovers her new seatmate, an ordinary-looking transfer student, is secretly the heir to a billionaire. Moved by her kindness and resilience, he quietly protects and helps her. Encouraged by him, Tori loses weight in a healthy way, regains her confidence, and transforms into a radiant beauty. Cole regrets his behavior and returns, but she firmly rejects him. In the end, Tori gains beauty, confidence, and her billionaire seatmate's true love.
