So I just finished this drama, and I have mixed feelings about it.

The drama centers about a very controversial plot: The aftermath of an assault victim , and her (and the the perpetrators as well) path to healing.

Pros: They show us the feelings of shame, anger, helplessness and victim blaming that Nina goes through and how they affect her in real life.
At the same time we are shown how the men start to understand how difficult it is to be a woman, and be blamed for the assault just because her skirt was not long enough, or some other dumb excuse society gives to the actions of men.
It really makes you think (and it is a very short drama so it's easy to watch) how prejudiced society is in general against women.

Cons: Honestly they bring a very mature theme in a very lightweight way that does not agree with the hole thing. They are very forgiving towards the perpetrators, trying to make you believe that while the assault is a bad thing, it's always forgivable.
While I think that the show is targeted to younger audiences (the drama happens in high-school) and they made it lightweight on purpose, such theme should be done in a more serious way.

In all, a very worth watch, and I have to say that I was pleasantly surprised (although the acting is a bit forced, but I think that is a bit of the way J-drama goes).
