Na Ae Ra made a mistake once, and boy does she regret it. Unable to cope with the stress of living in poverty and being a sole breadwinner for four years, she divorces her dull and deadbeat husband after he wastes their savings on a failing software development idea. Ae Ra never wanted to see Cha Jung Woo's loser face again.
However, three years down the line, while the business venture that separated the couple has made Jung Woo ridiculously wealthy, Ae Ra is still suffering with the debts that she incurred while they were married. When she finds out that Jung Woo is now a president in a massive venture capital firm, she begins plotting for her revenge on the unrepentant and unapologetic Jung Woo. Sly and single again, will Ae Ra succeed in making the now-confident Jung Woo fall in love with her a second time?
