The best way I can describe this is as a male model campaign dressed up as an agency of undercover tough guys.

The ML is there purely to look good, which, he does. I'm going to guess he is a model and not so much an actor, as that's exactly the way he came off as.

The story had all the elements that made for a good story, without utilizing them to actually tell a good story. You can actually find most of the elements in this drama, but with male actors instead of male models, in Stealth Walkers, so skip this drama and watch that one instead.
