It's been such a long time since I've discovered such an amazing, interesting action Kdrama. Typically, action dramas all have around the same plot, but this one in particular, is SO good. It has romance, but not enough to make it annoying. I love how he remains a stable, revengeful mind throughout the whole drama and doesn't give up regardless of the fact they're literally fighting against the government. This drama gives off the vibes of "don't trust anyone" because that plot twist was something I never expected. Despite the amazing plot and storyline, the ending was fucking disappointing. I was 3/4 into the last episode and started to wonder, how on earth will these 20 minutes give us a proper and satisfying ending? The answer? It won't. For an ending like that, I'd expect a season two or something but no, it's been like five years. Truly an amazing plot put to waste just because of that ending.
