Cha Yoon Seo runs an animal hospital in Dalsan-ri, South Korea. In the first episode, Cha Yoon Seo ends up in Seoul for a veterinarian reunion. On her way back from the reunion, she stops at a convenience store where she has a chance meeting with Lee Kang Hoon, the CEO of a famous corporation D.O.L. In episode 2, Lee Kang Hoon is kidnapped and eventually stabbed by the kidnappers. Lee Kang Hoon is able to fight his way out of the situation but, due to his injury, he ends up on the front step of the animal hospital. Cha Yoon Seo stitches up Lee Kang Hoon and he ends up falling asleep at the animal hospital. When he awakens, he calls his secretary and gets a ride home. While in the car, Lee Kang Hoon gets a call from his mother inquiring where he has been and then immediately starts telling him he needs to go on blind dates so that he can get married.
In the next few episodes, Lee Kang Hoon wishes to repay Cha Yoon Seo by buying her a new animal hospital in Seoul so that she can acquire more business. Cha Yoon Seo does not appreciate the gesture as he does everything in his power to force her to take the offer. She eventually caves and opens the Apsung Animal Hospital in Seoul. Eventually, as Lee Kang Hoon and Cha Yoon Seo get to know each other, Lee Kang Hoon proposes a contract relationship so that Lee Kang Hoon's mother stops pushing him to go on blind dates. While in the contract, Lee Kang Hoon and Cha Yoon Seo begin to develop feelings for each other and begin to officially date. However, once Lee Kang Hoon's mother comes into town, she does not approve of the relationship. Cha Yoon Seo is from rural South Korea and her parents own an apple orchard. As such, she is considered lower class and not considered worthy of Lee Kang Hoon, according to the mother's standards.
Lee Kang Hoon's mother wishes to test Cha Yoon Seo's love/loyalty to Lee Kang Hoon and tries to force her to sign another contract. The contract has strict rules which Cha Yoon Seo refuses to sign. Afterwards, Cha Yoon Seo goes back home to help her family at the orchard and refresh. However, Lee Kang Hoon is determined to marry Cha Yoon Seo and ends up finding her at the orchard where they are reunited. Lee Kang Hoon and Cha Yoon Seo ended up marrying each other and they live happily ever after.
