I have been watching this show since season 1, and I fell in love. I've watched the season 2 and fell in love for second time around and now currently watching season 3 and I felt the same when I watch 1 & 2 I am so engrossed of this show, seriously. This show never fail. I love it! I'm a big fan of Insung, Lim Ju-Hwan, Cha Taehyun and Yoon Kyungho and the other cast. I hope there is season 4 and it would be very nice and cool if there is. Saranghae all!
