What if marriage was just a business deal? Park Minho, the heir to one of Korea's largest corporations, thinks it might be the way to please his ever-discontent father. No messy feelings, no one gets hurt. To his surprise, he stumbles upon Lee Jinyoung. She might not have the conventional credentials or looks of his other potential matches, but she's on the same page about marriage. Scarred by her own past and too busy for love, Jinyoung agrees to play the part of the perfect wife and daughter-in-law in exchange for financial support. After sealing the deal on their contract, the question lingers: can their "love" story ever turn into something more?
