On the 9th episode of "Cunning Single Lady" broadcast on March 26th, Cha Jung Woo (played by Joo Sang Wook) realized that the person that Gook Seung Hyun (played by Suh Gang JooN) liked is Na Ae Ra (played by Lee MIn Jung).

On this day, Gook Seung Hyun saw Na Ae Ra having a serious face on the rooftop and told her to lighten up and joked. As Gook Seung Hyun used his hands to straighten Na Ae Ra's frown, Na Ae Ra couldn't calm her anxious heart.

However, Cha Jung Woo was also on the rooftop and saw the two friendly. Cha Jung Wo finally realized that the person that Gook Seung Hyun liked was Na Ae Ra.

In the end, Cha Jung Woo said to secretary Gil Yo Han (L), "My good friend said that he'd go out with my ex-girlfriend. Isn't this scandalous? What do you think?" and showed he paid attention to Na Ae Ra.
