Yu Hee, the Witch.

As the director of her father's advertising company, Ma Yoo Hee is known as a witch for her ruthless, no nonsense character. After a string of failed attempts to hire a housekeeper, she (literally) runs into Chae Moo Ryong, ex-medical student turned aspiring chef. As a way to work off his debt for crashing into her car, he agrees to become her housekeeper and personal love affairs coach for one month. Gladly, he gives her a makeover that attracts both her old friend Johnny Kruger and her first love Joon Ha. Despite having a girlfriend, Sung Mi, Moo Ryong eventually finds himself falling for Yoo Hee.
