I love this show. I have watched it many times, I have watched the videos on youtube, and have loved every minute of it. Five guys from very different walks of life coming together to form a team in a VERY short amount of time and being great at it is amazing. The way they support each other and teach each other is really inspiring. It's also hilarious! Kim Shin Young and Lee Teuk as the managers are so funny, I laugh so much while watching. I am also a huge fan of Jang Yun Jung, I love her voice, her songs, her work ethic and the way she looks after the guys like a Mom.
If you haven't watched it yet, you should, it is as I said in the headline, pure entertainment.
