In "Twenty Again" Lee Sang Yoon was angry at Choi Won Young and told her that he knew all about the affair.
On the episode of tvN Friday/Saturday drama "Twenty Again" (script So Hyun Kyung, director Kim Hyung Shik) broadcast on September 26th, Cha Hyun Suk (played by Lee Sang Yoon) knew about the extramarital affair between Kim Woo Chul (played by Choi Won Young) and Kim Yi Jin (played by Park Hyo Joo) and exposed this.
On this episode, Hyun Shik talked about taking Ha No Ra (played by Choi Ji Woo) to the picnic instead of Lee Jin. He said, "I took her because Kim Yi Jin is your woman. So just take care of her soon."' In addition, he said to Woo Chul and screamed, "If you dare affect No Ra's school life just a little, I'm going to not take it sitting down.'
Woo Chul was startled but then realized that he had feelings for her.
Meanwhile, "Twenty Again" is about a woman named Ha No Ra who had been a mother since she had her child at the age of 19. She becomes a new college student as this drama deals with all the episodes that happen.
