This drama hit me differently.
It is not an ordinary cliché drama, it goes so much deeper and lets you think about it even after a long time...
In the beginning I couldn't even imagine that this short 4 hours long drama could made me that sentimental. The main character Yoo-Tan really annoyed me in the first episode. But then... everything changed all of a sudden. I even cried in episode two.
It was one of the best dramas I've watched so far, but still, I think I won't rewatch it all by myself because the plot is so powerful and deep... It wouldn't hit me the same.
One sad thing about the drama is that you won't get to listen to the OSTs because the producers never released them:( The music is beautiful, though.
So, if you're considering whether to watch it or not, DO IT! It is so worth it.
