This show is so simple and it's the best thing about it..It is free from all negativity and is one which you can call truly feel good.It has the positive air in each and every episode. Jung so-min has done a very good job in portraying her role..and Kim Hyun Joong is so handsome..all other actors are also very good,especially younger brother of Baek Seung Jo..he is so cute!! I really liked the depiction of relationships in the drama.. All in all..a must watch..I have already watched it twice..
