"Yawang" Kwon Sang Woo begins to work with the Baek Hak Group to bring Soo Ae down.

In the 20th episode of the SBS drama "Yawang" that aired Marhc 19, Ha Ryoo (Kwon Sang Woo) secretly meets with Baek Chang Hak (Lee Duk Hwa), the president of the Baek Hak Group, to make a shocking proposal.

During the meeting that was set by Baek Chang Hak's invitation, he reveals all the secrets about his past to Ha Ryoo and asks him for help. Baek Chang Hak had previously been threatened by Joo Da Hae (Soo Ae) and needed Ha Ryoo as a shield against her.

Ha Ryoo accepts Baek Chang Hak's request for help under one condition.

In addition, Ha Ryoo asks Baek Do Kyung (Kim Sung Ryung) for help as well. The official cooperation of Ha Ryoo and the Baek Hak Group will lead to Joo Da Hae's plans to fall.

After Ha Ryoo's continuous efforts, Joo Da Hae was finally taken by the police station as a suspect for Baek Do Hoon's death at the end of the 18th episode.

Meanwhile, Joo Da Hae had been shamelessly chasing her dreams of becoming the first lady. Knowing what Joo Da Hae is after, Ha Ryoo plans to attack her Achilles heel in order to bring her down. Ha Ryoo's older twin brother Cha Jae Woong (Kwon Sang Woo) had been a lawyer and left some confidential documents that show Suk Tae Il's (Jung Ho Bin) background, which could possibly bring him down.
