After being dumped by her boyfriend just before their 100 day anniversary, Ha-Yeong (Ha Ji-won) meets a college guy named Hyung-Jun (Kim Jaewon) when she kicks a can that accidentally hits him in the face and causes him to scratch his Lexus. He demands she pay him $3000 on the spot. She escapes from him, leaving her wallet behind. Hyung-Jun stalks her, demanding money to pay for his car. Since she is a poor high school student Hyung-Jun writes up a "Enslavement Agreement" for Ha-Yeong in order to pay for the damage to his car. Ha-Yeong is thrown into a nightmarish slave life for 100 days, running his errands, i.e.: cleaning his house, carrying his shopping, and cleaning his car. By accident she finds out that the damage to Hyung-Jun's car costs only $10. She then takes her revenge by damaging his car and his reputation. But Hyung-Jun takes revenge by becoming her new tutor this brings them close to each other and they realize they love one another. Hyung-Jun frees Ha-Yeong from slavery and kiss her.
