I finished this and it was AWESOME!!! The story is very unique, love story, yes, but the twist is not like any other drama I have watched. I wanted to finished it so bad, but at the same time I want to savor it... YES IT IS WORTH the 16 hours. The male lead actor, Jo In Sung, was very impressive in his acting - he showed all kinds of emotions, he can be a very all-together guy one moment and then how he acted the vulnerability of the character was amazing. I became a fan.
