I love this show BUT...
...honestly guys, it does also deserves the award for the worst wardrobe EVER on a show. It's especially true for the guys. I highly doubt that a director would dress anything like Min-Hyuk. LOL At least you can expain the way Rain's character dresses with the fact that he his a pop star....hence the absolute right to be tacky.
Nonetheless, you would have to be seriously immunne to good series not to enjoy this one. Everyone does a really good job. It's highly enjoyable.
