"Yawang" Kim Sung Ryung decides to take matters into her own hands to revenge the death of her son.

Recently, an episode of the SBS drama "Yawang" featured Baek Do Kyung (Kim Sung Ryung) overcome by her fury about the death of her son Baek Do Hoon (Jung Yun Ho) and deciding to take matters into her own hands to revenge Joo Da Hae (Soo Ae).

Previously, Baek Do Hoon was killed by the explosives Joo Da Hae had set up in a car. When Baek Do Kyung figures out that Joo Da Hae is behind this murder, she decides to take revenge. Baek Do Kyung pretended to be Baek Do Hoon's older sister for over 29 years and she couldn't even hear him call out to her as mom before he died.

During the episode, Baek Do Kyung follows after Joo Da Hae who leaves after a short argument. Baek Do Kyung is holding a sharp pair of scissors and only had revenge on her mind.

Baek Do Kyung stabs Joo Da Hae in the stomach. Right then, Ha Ryoo (Kwon Sang Woo) appears and stops her from doing anything more damaging.

While Joo Da Hae is half unconscious, Ha Ryoo says, "Do you think you would feel all better if you killed her with your own hands?" Baek Do Kyung replies, "I can't keep watching that animal walk around with her head held high."

Ha Ryoo then says, "You have to be cold and unattached."

Baek Do Kyung replies, "How can I be unattached. Do you know what it feels like to lose a child? I'm going to kill Joo Da Hae."
