So far, this is the 1st OCN thriller drama that I found boring. To be honest I am dissapointed on this drama, I've known this drama for so long, but i only have the time to watch this recently, and in my opinion it is not that good. I have a high expectation in this drama since the title and the poster looks cool and I know that OCN doesn't dissapoint when it comes to crime/thriller/mystery dramas. But yeah, I was wrong.

The acting of the main leads are weak, they don't have a strong impact and a chemistry. I wasn't even hooked up on the story from the 1st episode. I think the story is nice, but I find it lacking and dull. Really sad that it didn't met my expectations.

I'll just give it a 4/10. You can watch it if you want too, but I believe there's a lot of OCN thriller dramas that are better than this.
