In "Twenty Again" Park Hyo Joo took hold about the relationship between Choi Ji Woo and Lee Sang Yoon.
"Twenty Again" is a story featuring Choi Ji Woo as a person who goes back to university. After feeling undereducated with her husband, she decides to get an education and also a divorce.
On the 11th episode of the tvN Friday/Saturday drama "Twenty Again" (script So Hyun Kyung, director Kim Hyung Shik) broadcast on October 2nd at 8:30PM, Lee Jin (played by Park Hyo Joo) misunderstood the relationship between Woo Chul (played by Choi Won Young) and Hyun Suk (played by Lee Sang Yoon). She thought that Hyun Suk had sent flowers and not Woo Chul. Nonetheless, with the mistake of the flower deliverer, the memo was lost. With Lee Jin thought that Hyun Suk had sent flowers. Afterwards, Lee Jin went to Hyun Suk to see how Hyun Suk felt. With that, he saw Hyun Suk and No Ra (played by Choi Ji Woo) in the alleyway.
The two people were surprised to be speaking so informally. With that, the two were assumed to be friends after going to the same arts high school. In addition, finding out that Woo Chul had been looking at the two people, he got a sense of what the relationship between the three were.
