It started off well. The first 9 or 10 episodes were good but it became really boring after that character called Ah Sa Nyeo came.

It was also a little stretched. They could've finished it off in around 16 episodes or even less. It seemed like they wanted to make it with 20 episodes of 1 hour 20 minutes each. It became a little interesting towards the end though.

I liked Cha Seung Won's acting. He's a great actor. Son Oh Gong and Devil King Woo's bromance is what made me watch this till the end.

It's worth watching if you have a lot of patience. I won't recommend it to anybody.
