To be fair, for me the rating is actually something like 8.8/10.

As i said earlier, the acting is really good on this one, the whole cast did a FANTASTIC JOB, but the LEAD COUPLE was really really well casted! a round of applause to them, i think they actually carried this drama, i hope they will win a lot of awards, they deserve it.

There were too many cliches, i hope this drama was more original, less predictable....
Some characters were unrealistic, like come on, in real life this would have never happened.
The villain could have been written better. I hope Park Sung Hoon will get the recognition he deserves and maybe play the good guy next time lol.

I actually recommend it, watch it and make your own opinion of it, don't be swayed by the bad reviews. It is not the perfect drama but it is enjoyable, and Kim Soo Hyun and Kim Ji Won are the lead! like come on, what else do you need to give it a try!?
