"Yawang" When Kwon Sang Woo proves that Soo Ae's alibi is fake, the police begin re-investigating people related to Jung Yun Ho.

During the 19th episode of the SBS drama "Yawang" that aired March 18, Ha Ryoo (Kwon Sang Woo) proves to the police that Joo Da Hae's (Soo Ae) alibi is fake and reopens the investigation for Baek Do Hoon's (Jung Yun Ho) murder.

Previously, Ha Ryoo had told the police that Baek Do Hoon's killer is Joo Da Hae. However, she had a perfect alibi set up. She had told the police that she bought a fountain pen during the time of Baek Do Hoon's accident. The person working at the store told the police that she went back to exchange the fountain pen she purchased that morning. The police even took the records of the customer's card payments.

Clearly aware that Joo Da Hae's alibi is fake, Ha Ryoo tries to find out how the alibi was created. He soon figures out that Joo Da Hae asked somebody else to go to the store to buy the fountain pen with her card and notifies the police.

The police show a picture of Joo Da Hae to the employee of the store and asks if they recognize the person in the photo. The employee says, "I don't know if this woman bought the fountain pen, I just remember her coming here to exchange it." As Ha Ryoo had said, police searched through the security cameras and found out that Joo Da Hae does not appear at the store during the time of Baek Do Hoon's accident.

They begin investigating Joo Da Hae and Joo Yang Hun after Ha Ryoo alerts them that Joo Da Hae's step brother Joo Yang Hun (Lee Jae Yoon) is helping her. Joo Da Hae and Joo Yang Hun begin to hesitate.
