Plot
this drama had a a lot of potential, but it kind of missed the mark. The storyline was all over the place. you could not understand why the people killed the others and they barely touched on the main reason why brother got killed. And these high school kids where not acting like high school kids and overall the revenge fell short. And not to give out to much the revenge was mid.

characters
you could not sympathize with any of them and it’s was too far fetched and they acted so foolishly and especially the main female lead. And the bad guys just seemed to lack depth like if you are evil ? they should be a reason why you are like that except if you are a sociopath.

missing the mark on important issues
they take to lightly the fact that some issues where not fully explained like being GAY , sexual harassment, bullying and death ?

overall
invite this drama a 5.5 if you are looking to watch a quick bad bad show this is for you because they are moments where you get excited but it falls down so quickly. would not recommend this for first time drama watchers
