As you can see in the picture above, Jang Geun Suk posed with his face half covered with a blue towel and his eyes rolled up, showing only the whites in his eyes. With all that, I agree that he does look like a zombie. He seemed to be doing it on purpose for a reason we do not know.
Maybe he’s getting ready for Halloween? Who knows. Don’t blame me if you get a nightmare tonight after seeing this.
