Yu Hee, the Witch(2007)

Yu Hee, the Witch is a romantic comedy series about Ma Yoo Hee, a ruthless advertising executive nicknamed "the witch" for her cutthroat management style. When she literally collides with Chae Moo Ryong, a failed medical student turned aspiring chef, he agrees to work off his debt by becoming her housekeeper and dating coach for one month. Moo Ryong transforms Yoo Hee's image, drawing attention from her old friend Johnny Kruger and her first love Joon Ha. As romantic complications mount, Moo Ryong—already in a relationship with Sung Mi—finds himself unexpectedly drawn to the woman he was hired to help. The series balances sharp workplace drama with genuine chemistry as two unlikely people navigate professional boundaries and unexpected feelings.
