Lee Yeon Hee has been under fire for supposed attitude problems recently, and a fellow actor's past comments about her have resurfaced.

Actor Kwak Do Won was asked, "How does Yeon Hee unni look in person?" He had replied, "Yeon Hee's face is pretty, but more than that, her heart is about a million times better and her personality is tens of million times better. I'm completely serious."

However, both SM Entertainment and the drama's staff have commented,�"Although it wasn't shown on screen due to editing, Lee Yeon Hee also clapped like her other castmates and showed her support for the actors and actresses."
