Ma Yoo-hee (Han Ga-in) is the heir of an advertising company. She is engaged in advertising planning. She is rigorous, capable, and independent. She is called a "witch" by company employees behind her back. However, this vigorous and resolute character does not work at all when it comes to blind dates, and blind dates end in failure again and again. Cai Wulong (Jae Hee) gave up his studies at the medical university and turned to the chef industry he likes, hoping to become a first-class Western cuisine chef. In an accidental car accident, he damaged Yoo-hee's luxury car and owed Yoo-hee a large sum of repair money, so he began his tangled love story with Yoo-hee. However, their love is not smooth sailing. The "ice and fire" gap in personality, the obstruction of parents from time to time, and the complicated relationship between Yoo-hee's first love Jun-ha (Kim Jung-hoon) and Wulong's childhood friend Nan Shengmei (Jeon Hye-bin) are endless and complicated. A love comedy with endless jokes is staged.
