Joo Sang Wook got pettily jealous of Suh Gang Joon and Lee Min Jung which drew out laughter.

On the 9th episode of "Cunning Single Lady" broadcast on March 26th, Cha Jung Woo (played by Joo Sang Wook) sought a petty revenge on Na Ae Ra (played by Lee Min Jung).

Cha Jung Woo started to realize that Keuk Seung Hyun (played by Suh Gang Joon) whom he thought was like a younger sibling liked his ex-wife Na Ae Ra so he started to pay attention to the two people.

Cha Jung Woo was jealous at the two people looking friendly and started a petty revenge. At the workshop, Na Ae Ra plays a game of "The Morning Glories had bloomed" and slapped Ae Ra's back. Ae Ra didn't know what was wrong and got upset at Cha Jung Woo.

Meanwhile, on this day, Cha Jung Woo saw Seung Hyun confessing his feelings for Ae Ra by coincidence and made a confused face.
