Choi Kang Hee was jealous of Cha Hong Do who was her role.
On Feb. 18th, tvN released the making of video of Chun Jun Myung (played by Ko Yi Suk)'s love confession to comfort the disappointment of not airing episodes during Lunar New Year.
In the released media clip, Ko Yi Suk went to Cha Hong Do (played by Choi Kang Hee)'s house and said, "Cha Hong Do I love you" as he screamed his love confession to the world. Ko Yi Suk was going to hug Cha Hong Do in a tight way. He then said, "You always make me say things first. Cha Hong Do, I love you. You're mine, Cha Hong Do" he yelled.
Nonetheless, Chun Jung Myung had to act this out. He said, "Wow that's making me cringe" as he drew laughter from others. In addition, Choi Kang Hee kept on repeating, "Cha Hong Do, I'm not jealous of you."
Meanwhile, tvN "Heart to Heart" airs every Friday and Saturday at 8:30PM. It features a story of Cha Hong Do who suffers from social phobia and has a problem with blushing whenever she's in public. Nonetheless, with a sense of curiosity, she learns about the outside world through books and the Internet. This romantic comedy shows her romantic adventures as she falls in love with her psychiatrist, Ko Yi Suk.
