In "A Valid Love" Um Tae Woong found out about Lee Shi Young and Lee Soo Hyuk's relationship. At this moment, they were on a picnic date together.
On the 7th episode of the tvN Monday/Tuesday drama "A Valid Love" (producer Han Ji Seung, script Kim Do Woo) broadcast on December 22nd, Jang Hee Tae (played by Um Tae Woong) found out about the relationship between Kim Il Li (played by Lee Shi Young) and Kim Joon (played by Lee Soo Hyuk).
On this day, Jang Hee Tae received a text from a man that he didn't know. The text read, "I know what your wife did." Moreover, during dinner, Jang Hee Tae received a text with a lot of picture attachments. In the picture, Kim Joon (played by Lee Soo Hyuk) was holding Kim Il LI (played by Lee Shi Young)'s hands as she was walking into a room with him.
Jang Hee Tae was flustered and went to look for where Kim Il LI went. Nonetheless, he could contact Kim Il LI. He had tried to deny but his wife's affair was pretty much a fact. Jang Hee Tae said that the soup that Kim Il Li had gotten from her mother had actually gone to Kim Joon as Jang Hee Tae started to fit the puzzle pieces together.
