On December 13, Cha Eun Woo appeared on KBS 2TV's 'Happy Together 4' as the special MC. During the show, Cha Eun Woo is asked which co-star, Lim Soo Hyang or Seo Eun Soo, made his heart pound more during filming.
Cha Eun Woo worked with Lim Soo Hyang on the drama 'My ID Is Gangnam Beauty,' and Seo Eun Woo on the web drama 'Top Management.'
The idol star answered, "I think it depends on what scene. I had a kiss scene with Lim Soo Hyang but not with Seo Eun Soo." The MCs continued to ask for a specific answer. Cha Eun Woo failed to pick one person and said, "Lim Eun Soo."
