One of the best dramas that i ever seen in my life. I never got bored. I enjoyed every second of this drama.
The acting was great.
The story was unexpected and nonusual and funny and strange and romantic sometimes and dramatic.  
It wasn't easy to watch it because it contains many deep thoughts so it's requires a high concentration watching it.
I highly recommend to everyone that wants to think and wants to sit in front of pc or laptop or tv unmoved for the entire drama.
