yes Mandy, you are so true!
this drama is accomplished with so many factors,the casts who still young but have strong potential,the writer,the director,etc behind them and a strong plot with every details of capturing of the camera.
LMH before for me just a pretty boy,opps sorry for the fans,but now I admit him daebak!! but forever his way staring at eun sang can only be Kim tan's only

.
what I meant to say that is yes,the heirs need season 2 but there no way it can be done.if it is done they rarely came along with the same casts and how we can get the same caring Kim tan to cute eun sang here...no way...
in conclusion,if KES fell it is enough for all viewers,we couldn't be happier than a very happy ending yey!!
