Actor Lee Sang Yoon has a grim and determined expression. What happened?

During the latest episode of KBS2 weekend drama 'My Daughter Seo Young', Woo Jae (played by Lee Sang Yoon) found out about Seo Young's (played by Lee Bo Young) secret past. His trust in her had been broken so he had been acting cold towards her.

He used to always be an easy-going guy, but he suddenly changed. In the midst of all of this, Seo Young had been feeling nervous, but in the end, Woo Jae did not explain anything.

The upcoming episode shows that Woo Jae is still in love with Seo Young, but he is disappointed that she lied to him and has not told him the truth about anything so the misunderstandings keep on piling. Woo Jae looks to run a background check to find out the final truth.

As Woo Jae transforms from the perfect man, in regards to work and family, into a cold man, Seo Young's anxiety grows. She does not realize that Woo Jae knows about her past so she finds his actions frustrating as she cries endlessly.

The tension is heightened as Seo Young tries to avoid telling him the truth while Woo Jae already knows the truth.

'My Daughter Seo Young' airs every Saturday and Sunday at 7:55 pm.
