When I was thinking about watching this show, I was initially worried about why the rating was already so low. I ended up delaying it, thinking that it was probably average/not worth watching. It was only by chance, flicking through Netflix that it came on, and I WAS HOOKED!

From what I've gathered through the comments section, the low rating is due to C-drama fans bombing the ratings...
This show is actually surprisingly fresh, it has characters that have genuine motivations and also (it seems to me) a unique storyline.

So far, definitely worth the watch!
