In "Heart to Heart" Chun Jun Myung wanted to break up with Choi Kang Hee.
On the 9th episode of tvN drama "Heart to Heart" broadcast on Feb. 6th, Ko Yi Suk (played by Chun Jung Myung) finally stated that he wanted to break up with Cha Hong Do (played by Choi Kang Hee).
On this episode, Cha Hong Do saw Ko Yi Suk when least expected. He was hugging his ex-girlfriend. Seeing this, Cha Hong Do was shocked and fell to the ground. At that moment, Jang Doo Soo (played by Lee Jae Yoon) happened to come to the hospital. He dragged Cha Hong Do outside.
Jang Doo Soo said, "I came because I needed to say something to that jerk. But from the looks of it, it seems like whatever I was going to say was not necessary." Jang Doo Soo was upset. Cha Hong Do said, "There must be some sort of reason. I'm going to ask." With this, she showed that she still had faith in Ko Yi Suk.
Nonetheless, Cha Hong Do was shocked seeing Ko Yi Suk coming out of the hospital with Woo Yeon Woo (played by Hwang Seung Un). There, she remembered that Woo Yeon Woo was Ko Yi Suk's former girlfriend.
