Plot
Baek Soo-chan is a playboy infamous for manipulating women. After meeting Jung Yoon-hee and her older sister Mi-hee on vacation, he puts the moves on them as usual, but Yoon-hee sees right through him, and tries to keep him away from her naive sister. Fate draws them together again, however, when back in Korea, Soo-chan ends up living next door. Meanwhile, Yoon-hee begins working as secretary to Yoo Joon-seok, the new president of her company. Forced to come back and take over their family business when his father suddenly collapsed, Joon-seok shoulders the burdens of corporate responsibilities and of trying to please a father who has never shown him any affection. At first the perfectionist Joon-seok clashes with his quirky secretary, then gradually begins to fall for her. But Joon-seok's arranged marriage to Go Hye-mi, an heiress, is already being planned.
