They gave so much hype to the series. But didn't workout. This series have the same story as dokgo rewind season 2 (which was supposed to happen, but didn't happen). In dokgo rewind season 1 they ended as there will be a 2nd season also the main plot was revealed too. Surprisingly hierarchy have the same story lol? . Also the main lead actress don't have emotions while playing it's really hard to know whether she is acting or not. Some may say it's because of her role...but we have seen many actors playing the same type characters, even though in these type of character they may show some emotion so that we could literally understand what they are trying to convey. Also in the end male lead doesn't have the real revenge. In the end director just want to make like the heroine is innocent,she didn't do anything wrong, she is always right and also she's the main soo she can't down like that. When her boyfriend (2nd lead) was bullying main hero's brother she was just looking at that and didn't even care about that. Not just that she is the reason for hero's brother got bullied. Even though in that situation director tried his level best to prove she innocent, she is scared and she is conquering..But in the same time hero was trying his best to solve this and truly loving her. The 2nd hero's bullying led to the death of hero's brother (not saying they are fully responsibile, but they are playi g major role in that incident). If they do bullying, they must be punished. Instead of that heroine gone against hero and trying to save 2nd hero. On that time the main content was changes. Just like the main hero did something wrong and heroine is right and she is doing the right thing. All faults was by the heroine. And director tried to glorify her actions. That's the failure. Her character build up and story ending make the whole series a failure. If dokgo rewind 's 2nd season release, we could see the story focused series. I hope they would do the 2nd season (2nd season of dokgo rewind). And don't release the 2nd seasons of hierarchy. As a k drama lover it's an utter disappointment to watch hierarchy. 1.5/10 my rating to the hierarchy
