In "Mask" Soo Ae chose Joo Ji Hoon instead of her family members.
On the 9th episode of SBS Wednesday/Thursday drama "Mask" (script Choi Ho Chul, director Boo Sung Chul, Nam Gun) broadcast on June 24th, Byun Ji Sook (played by Soo Ae) started to have an internal conflict. She was torn between her younger sibling Byun Ji Hyuk (played by Ho Ya) and his life and her husband Choi Min Woo (played by Joo Ji Hoon). Byun Ji Sook had been acting like Suh Eun Ha.
Min Suk Hoon (played by Yeon Jung Hoon) was not happy about the relationship of Ji Sook and Min Woo. The two were getting closer and closer, and Suk Hoon was not happy with this. In addition, things with Min Woo's work were getting better and better. With that, he threatened Ji Sook with Ji Hyuk's life as a lump sum collateral.
In the end, Ji Sook was deep in contemplation and saved Ji Hyuk. She decided that she wanted to save her sick mother and did what Suk Hoon wanted to do. The situation as that Min Woo had been framed. He had been framed for the murder of Kim Jung Tae (played by Jo Han Sun) because of Suk Hoon's scheme. Suk Hoon gave two pieces of conclusive evidence in Min Woo's study and Ji Sook was startled to see the evidence from Suk Hoon.
