This is a very predictable subject I've noticed with Korean dramas around bullying. But I love how it was done in an unpredictable way. I have to admit this probably wouldn't have gotten great reviews if it wasn't for the amazing acting by all the leads. The male lead was phenomenal one of the best performances I've seen in all of year long. I love how I wasn't sure what was going to happen next.

I was fine with it but I was amazed by the graphic nature of the series. The action scenes were done very well.

The grittiness of this drama remind me a lot of another drama called Extracurricular. I appreciate that it was a nice tight eight episodes so it did not contain a lot of filler episodes and one too many origin stories.
