The cable channel JTBC's Monday Tuesday drama "Secret Love Affair" Oh Hye Won, played by Kim Hee Ae, decided to protect herself and Lee Sun Jae, played by Yoo Ah In, from people around them, as their love affair got more and more serious and people learned of their affair.

On the thirteenth episode of the cable channel JTBC's Monday Tuesday drama "Secret Love Affair" which aired on May 6, 2014, Oh Hye Won and Lee Sun Jae decided to distance each other for a while until things settle down a little bit, after their love affair was uncovered. Oh Hye Won has been helping her boss Suh Pil Won, who was in jail for a trial. On that day's episode, she received a stack of cash from him, who told her, "Thank you for all you did up until now," and realized that she might be in danger. She decided to see Lee Sun Jae and tell him to distance himself from her to protect both of them from her boss, his family, and others. She said to Lee Sun Jae, "Please listen to me. I am going to pretend as if Prof. Kang and I are a really good couple. So please stand and watch us. I do not want to ruin everything I have accomplished until now, what I would have in the future, and you. So please hide well until I win everything." Lee Sun Jae still wanted to run away from everything with her, and said, "Please think of what is more important in your life first." At the end of the episode, he got frustrated when he had to hear Oh Hye Won and her husband Prof. Kang talk endearingly to each other at their place.
