That's a good one. I didn't think about it before
I thought about that too, but after reading some comments and hypothesis I can now understand that this dude may know MD already. Chamwoo asked him how he knew it was him from the show, and he replied that it was obvious and what not, so I’m assuming he also knows who MD is.
The new guy is definitely a fan of MD show that’s why he know Chanwoo, from MD show. But I am not sure if he know MD personally. If he know, he wouldn’t have asked Chanwoo to take him to MD.
Seriously I can’t wait for next week. Watch, MD would probably not answer or want to meet :(
I don’t think it’s a good idea to let other people know who MD is outside of his show. He do have a life of his own and by letting people know who he is, it may bring troubles to him, like a disruption to his personal life. Chanwoo should at least tell MD the situation first and ask for permission if MD want to reveal his identity to the man as MD or not because Chanwoo is bringing the man to meet MD as the DJ MD.
