The cable channel JTBC's Monday Tuesday drama "Secret Love Affair" Oh Hye Won, played by Kim Hee Ae, met Da Mi, played by Kyung Soo Jin, who was the ex girlfriend of her lover Lee Sun Jae, played by Yoo Ah In, from them.

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's secretary told her that the student from the hair salon, Da Mi, was in her office. Oh Hye Won greeted her warmly, but Da Mi told her not to meet Lee Sun Jae. She said, "You told me you would never see him again. But you met with him again, for two days and a night." Oh Hye Won tried very hard to stay calm, but she could not stop shaking. She tried not to look at Da Mi and said, "It is not polite of you to talk to me like that. You are at my workplace. I will contact you at a later time. Let's have food with Sun Jae."

Oh Hye Won has been brave in embracing her love affair with Lee Sun Jae and people's teasing. However, she shook her whole body confronting Da Mi. In fact, Oh Hye Won has felt inferior to her ever since she started liking Lee Sun Jae, because Da Mi was so much younger and prettier. In related news, cable channel JTBC's drama titled "Secret Love Affair" is a story of a forty something woman, Oh Hye Won, who is played by actress Kim Hee Ae, and a naïve genius pianist Lee Sun Jae, played by actor Yoo Ah In.
