I have to say... this is the BEST park shin hye drama! amazing in fact, the chemistry was beautiful :') ... it was a perfect balance of romance and drama, no cliches, just the epitome of perfection! especially the ending, never liked an ending of a drama as much as this one!!!! <3
p.s. note that this is a marathon drama, impossible to watch ep by ep

Great music!
Great casting!
Epic story line!
... need I say more?
