I binged this in one day, it was that good. story about a real life bullying event and just thinking about how this happened to someone is actually so insane.

Song Hye Kyo's character grows up to masterfully craft a foolproof revenge plot for her bullies and its so satisfying getting the justice she deserves, especially when she took it into her own hands to get that revenge.

Another thing is the chemistry between her character and all the others that she ropes into her plan because they want her to see her enact the revenge she deserves. goose bumpingly satisfying.

The actors and actresses who play the antagonists are so good you can't help but hate them.

I can't wait to see how part 2 plays out.
