It was rather too late to watch The King 2 Hearts but definitely I like it so much. It is my favorite drama in 2012. Ha Ji Won and Lee Sung Gi were so badass as a couple.
Back to previous year, Protect the Boss was my favorite drama. I rewatched many times. Jaejoong and Wang Ji Hye were the best second lead ever.
As I did to Protect the Boss, I rewatched the King 2 Hearts many times too. Each episode had a memorable scene that I couldnt forget except to watch it again and again.
