100 Day's With Mr. Arrogant

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. Ha-Yeongs moms sees this and threatens Hyung-Jun to stay away from her daughters life and brings a new tutor to teach Ha-Yeong.Ha-Yeong says to Hyung-Jun that she wants to marry him but he says that he only toyed with her. Hyung-Jun leaves his apartment which makes Ha-Yeong more vulnerable.She studies hard so she can get into Hyung-Juns college. After the exams she finds out she was not selected to enter the same college as Hyung-Jun,her tutor takes her to a place where she finds Hyung-Jun telling her that she was selected into his college but he wanted to give her a surprise. after a long time we see Ha-Yeong driving while a high school kid kicks a can that accidentally hits her in the face and cause her to scratch her Lexus. And it starts again!! . The original Korean title can be literally translated as "my love, the asshole," or, more roughly, as "my love, the no-manners".
