During a press conference for the new MBC drama 'Mister Baek' on November 3,�Lee Joon revealed the hardships that he's facing for his role.

The actor said, "Honestly, it's really hard. As I was filming, I realized how bad my acting was. I am having trouble mentally."�

He continued, "I seem bright, but I'm not. I don't really talk much either. The side that you see of me on variety shows is just part of who I am, but that is also when I had excessively high blood pressure. It's almost similar in the drama. I play a character who acts without thinking... I forgot all of my past acting. I'm trying to live cheerfully without thinking too much."�

As it was previously reported, Lee Joon's character is a second generation chaebol who suffers through people badmouthing him. Though minor employees to the directors of his company refer to him as trash and a roughneck, he has no intention to change their minds or be ashamed.�
