Unhak's arrogant acting, sticking on a temporary tattoo and asking "Hey, do you have any money?" is the highlight.

He said he video-called his mom and showed her his neck during the music video shoot.
I heard that my mother was surprised when I told her, "Mom, I got a tattoo."
I lied and immediately smoothed things over by saying I did it because of the music video. My mother must have been shocked.
