I find this show simply amazing to the point that, back then, I subscribed to Viki-pass just to watch this one.
First show for me with the super popular Lee Min Ho: I loved his character and how he played him.
But I absolutely ADORED Jun Ji Hyun: she is probably one of the best actresses I've ever seen and the way she goes from drama to comedy in a bit is unbelievable (though I already had the chance to appreciate her in You Who Came From The Star). Great chemistry between them.
Drama and comedy are quite balanced, too. Probably it could've been a bit shorter, but I don't complain, I liked it a lot.
