Actor Kwak Dong Yeon talked about two of his male co-stars. 

Kwak Dong Yeon has worked with Park Bo Gum on the drama 'Moonlight Drawn by Clouds,' and with Cha Eun Woo on 'My ID Is Gangnam Beauty.' 

On the March 6 airing of MBC's 'Radio Star,' Kwak Dong Yeon called Park Bo Gum "an angel without wings." He explained, "He is sincerely grateful for every little thing. You know, people just say thank you as a greeting but he's sincerely thankful. I learned a lot from him."

As for Cha Eun Woo, who is the same age as him, Kwak Dong Yeon shared he had trouble becoming close to him. He said, "We have a different sense of humor." Kwak Dong Yeon brought laughter as he added, "What I realized is that he is given so much but he has zero sense of humor."
