9/10 is my rating. This is a 2014 South Korean television series spanning 16, 60 minute, episodes.
Na Ae-ra (Lee Min-jung) grew up believing she was born to be only pretty and not smart. While working at her family's restaurant, she falls in love with Cha Jung-woo (Joo Sang-wook), a geeky engineering graduate student studying to enter a civil service job. Na Ae-ra wants to become a housewife, and after Jung-woo promises that she will be, they get married. During their 100th day wedding celebration, Jung-woo announces that he has quit his job because he has an idea for a business. Jung-woo's businesses keep failing and Ae-ra struggles to keep them afloat by working multiple jobs. After secretly suffering a miscarriage from the stress of being the sole breadwinner and living in poverty, Ae-ra divorces Jung-woo after four years of marriage. Three years after the divorce, Ae-ra discovers that Jung-woo has become fabulously successful and wealthy, while she is still paying debts that accrued during their marriage. The fun begins when Ae-ra schemes for revenge, with Jung-woo believing that Ae-ra wants him back because he has become wealthy.

Spoiler 🚨 This was not at all what I expected. I thought the ex-wife would be coming from a position of power at the outset and she really was not. I should be used to the premise not fully giving me insight into the complexities of the story line. it is part of what I love about Asian dramas. From synopsis I expected this to be similar to some American shows I have seen where exes get revenge - and it was not like that at all. I was also surprised at the sympathy I felt for the "villainous" characters and the unexpected evolution of some. I liked the way it explored the many levels of miscommunication that can go on in a marriage and the qualities that someone who should know you better than anyone might fail to see. It was moving, complex, but still light and refreshing.
