In "Mask" Yoo In Young pushed Yeon Jung Hoon to tell the truth. She would be accompanying him in an act of valor to tell the truth. She wanted him to go into the police station to make an official confession.
On the episode of SBS Wednesday/Thursday drama "Mask" (script Choi Ho Chul, director Boo Sung Chul) broadcast on July 29th, Choi Mi Yeon (played by Yoo In Young) felt incredibly guilty. With that, she was in pain and drowned herself in alcohol to drain her sorrows.
Afterwards, Choi Mi Yeon showed tears to Min Suk Hoon (played by Yeon Jung Hoon). To him she said, "Suk Hoon. Let's just turn ourselves in. I promised Min Woo (played by Joo Ji Hoon). That I would lead you and make you confess for your crimes. Once you confess, then I promise, I'll go forward and tell the truth too.
Nonetheless, Min Suk Hoon, "I didn't do anything wrong. So what do you mean to confess for something." With that, he rejected the offer of Choi Mi Yeon as he kept on his mask until the end. It will be interesting to see exactly how he can persist in creating a false identity and sustain the lies.
