Only reason I watched this was to Jang Na Ra. The sorry was interesting at first and I binge watched till the 10th episode. I watched 11th episode and felt like the show began loosing focus and so do I. I would recommend you to give it a try. Cause the story was good for the first 10 episode. I dropped it cause i think 11th 12th and 13th episodes were just way too boring. The cast was good but I didn't like the main actor don't know why but he felt unnatural.

In conclusion idea of the story is good but story getting boring later on. Cast is good. I recommend you to give it a try you might like it more than me.
