Plot
Na Ae-ra 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, a geeky engineering graduate student preparing to enter civil service. 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.

Main characters

 * Lee Min-jung as Na Ae-ra
 * Beautiful but flighty, Ae-ra initially cares more about honing her looks over her life skills. Upon marriage to Jung-woo, she dreams of becoming a housewife but finds herself shouldering the sole burden of their financial needs for four years, until frustration and exhaustion drives her to divorce him. But after learning of his success, she schemes to ostensibly win back her ex-husband by becoming an intern at his company, though what she really wants from him is a belated apology and a "thank you".


 * Joo Sang-wook as Cha Jung-woo
 * Despite being an engineering genius, he was initially studying to become a civil servant when he meets and marries Ae-ra. To her shock, Jung-woo suddenly announces that he's quitting to become a software developer instead. Years of his business failures lead to their divorce. Jung-woo eventually creates DonTalk, a WhatsApp-like text-over-data app that becomes Korea's No.1 social networking application. Thus Jung-woo transforms from a geeky loser into the self-made, successful president of D&T Software Ventures, a venture capital firm.


 * Kim Gyu-ri as Gook Yeo-jin
 * Smart, elegant, and capable, Yeo-jin possesses a keen insight and determination that can be intimidating, particularly given that she was born with the disposition of a boss. She is an heiress, being the daughter of the chairman of D&T Software Ventures, where she works as a director. She nurses painful scars from a past love, but falls for her business partner Jung-woo because of his warm personality, becoming Ae-ra's rival for his heart.


 * Seo Kang-joon as Gook Seung-hyun
 * Yeo-jin's younger brother, who was once tutored by Jung-woo when he was in high school. Good-looking, rich, and caring, Seung-hyun is seemingly a perfect guy. Upon his return to Korea from overseas, he gets hired at DonTalk despite his resistance to working a desk job at his father's company; but to avoid preferential treatment, he hides his real identity. Among his fellow interns is Ae-ra, and he becomes attracted to her, notwithstanding their eight-year age difference.
