When you grow up in extreme poverty, the experience can instill a steely resolve to succeed at all costs. Joo Da Hae (Soo Ae) is determined to leave her life of poverty behind and will stop at nothing until she achieves the wealth and lifestyle she so desires. Ha Ryu (Kwon Sang Woo), who loved Da Hae and would have done anything for her, is used and betrayed by her in her greedy quest. He later becomes a public prosecutor who must bring her down. But the heartless Da Hae, who rises to become First Lady, has plenty of others who will sacrifice themselves at her whim, including the smitten Baek Do Hoon (U-Know Yunho of TVXQ). Can the ruthless Da Hae be stopped before she goes too far? “Queen of Ambition,” also known as “Yawang,” and “Night King,” is a 2013 South Korean drama series directed by Jo Young Kwang and Park Shin Woo and based on the manhwa written by Park In Kwon.
