Forget the clean-cut, hardworking Jang Geu Rae from 'Misaeng'!  Siwan lets loose in a new pictorial with 'W Korea'!

The grungy, laid back, bummish concept must be what's in in Korea right now because recent pictorials portray idols au naturale with less editing for complexion perfection and more effects for a grunge look.  The fashion following this pictorial trend seems appropriate for a rocker hanging out in a hotel, but in this case, Siwan goes for bum casual with ripped jeans, training jackets, and an unkempt, greased up hairdo.  How does he still manage to look so good?

Always known for his well-groomed, pretty boy appearance, Siwan proves his looks can actually be quite versatile by tackling a new image with success.
