Could she have been a little too rash in divorcing her husband? Na Ae Ra (Lee Min Jung) marries the nerdy genius Cha Jung Woo (Joo Sang Wook) but divorces him when he fails to achieve the success she wants. Although a little self-absorbed, Ae Ra learns that life is not that glamorous as a divorcée and learns to live on her own through sheer hard work. But when Ae Ra finds out that her ex-husband went on to achieve success after their divorce and is now the president of D&T Software Ventures, a venture capital company, she schemes to win him back. But can Ae Ra carry out her plan when Gook Seung Hyun (Seo Kang Joon) has his eyes set on her and his older sister, Gook Yeo Jin (Kim Gyu Ri), also vies for Jung Woo’s heart? “Cunning Single Lady,” also known as “Sly and Single Again” and “Devious Divorcée,” is a 2014 South Korean drama series directed by Go Dong Sun.
