Joo Sang Wook and Suh Kang Joon started to have a tight mental battle over Lee Min Jung.

On the 11th episode of MBC Wednesday/Thursday drama "Cunning Single Lady" broadcast on April 2nd, Kook Seung Hyun (played by Suh Kang Joon) confessed his feelings for Na Ae Ra (played by Lee MIn Jung) and had a tight mental battle with Cha Jung Woo (played by Joo Sang Wook).

On this day, Cha Jung Woo picked a fight with Kook Seung Hyun for no reason. He had bothered him saying, what kind fo car does an intern carry around? More than that, he was jealous in a petty way saying, "I hope you're not trying to do something with this?"

Kook Seung Hyun saw Cha Jung Woo's not so cool actions and said, "Honestly, isn't it that you want to delete the memories of your ex-husband?"

However, Cha Jung Woo said, "You say you're an expert, do you not know women? Women have a standard that is built on the guy they met before. They have to compare this" and picked at his words.

However, Seung Hyun didn't back down. He said, "So what do I lack compared to you guys? I'm tall and young and I have strength too" urging him on.

Meanwhile, on this day, the two people had a petty fight over Ae Ra and made people laugh.
