Yoon-hoo and Gook-hwa story Several stories go on throughout the show, and the main story is the one focusing on the development of Gook-hwa and Yoon-hoo's relationship. At the beginning, Gook-hwa and Yoon-hoo hate each other - Yoon-hoo despises her love for money and for behaving like a country bumpkin, while Gook-hwa detests Yoon-hoo's hot-tempered, icy exterior. He gives her the nickname "farm girl" because he finds her behavior crass. However, when Gook-hwa gets a job as Yoon-hoo's secretary, partly because of her ability to speak fluent Mandarin, Yoon-hoo gradually falls in love with her, as she is able to make him laugh and feel "alive" through her naivete and innocence. Shin-hyung (), Yoon-hoo's childhood friend whom Yoon-hoo's parents want him to marry, notices the change in Yoon-hoo's attitude toward Gook-hwa, and is uncomfortable when Yoon-hoo appears to be getting closer to Gook-hwa, despite their upcoming wedding date.
