It reminds me on some of the great tvN and OCN hardcore crime dramas back in the day, though it now becomes more of a rare genre these days. This drama going digital on TVING is actually a wise decision, there's no more limits on the level of gore and psychotic scenes, which makes it intensely sick. The concept is extremely terrifying yet it feels so convincing because the sentiment is so strong in here. A technical reasoning on the separation between predators and weaklings, how some are able to gloss over their sins so easily and how some will be suffering for the rest of their life in this completely hopeless world, this drama will be able to speak for losers out there, fictionally at least.
