Seo Hye-seung (Kim Hee-sun), a housewife with a daughter, found her life turned upside down when her husband asked for a divorce. Not long after, her husband commits suicide. It turns out his mistress, Jin Yoo-hee (Jung Yoo-jin) scammed him, making him accountable for an embezzling job she pulled.
Hye-seung finds an opportunity to take revenge when she meets Yoo-hee in a marriage-arrangement establishment named Rex that caters to rich clients. Hye-seung vows to make sure Yoo-hee does not get what she wants, especially the super-rich CEO Lee Hyeong-joo (Lee Hyun-wook).
The best thing about this drama is the length, just 8 episodes. However, it seems that characterization and relationship development were sacrificed for the sake of brevity. Nevertheless, it was still a satisfying watch.
