Synopsis
Marketing Department Manager, Nam Jung-gi (Yoon Sang-hyun) is so nice that his colleagues call him "Father Theresa" and "Walking UNICEF". There is nothing that can ruffle Jung-gi's feathers but his new coworker from their main competition, Ok Da-jeong (Lee Yo-won), who is so nasty she's been nicknamed "Ms. Temper", and isn't impressed with Jung-gi's affable nature. A figure from Ok Da-jeong's past makes it his mission to destroy the one thing that she cares about, and puts the company's livelihood on the line. Despite their differences, will they be able to unite to save their company?
