I was drawn to the overall premise. A victim dedicates her whole life and personality to seeking revenge on her high school bullies. You can see the PTSD and long term injuries she faced as a result of the extreme violence, even over 15 years later. And that, is to show just how much of an impact bullying can have on a person, which Korea really should learn by now.

Every episode being less than an hour was a huge blessing, and I sped through the first couple eps. But then, the drama slowed down a lot, more than I am used to. They cut to a different scene often to focus on each of the many characters, but the scenes themselves are boring to watch. This drama is an example of nothing's going on, but actually everything's going on.

The casting bothered me a lot at first. The older version of the male students looked believable, and so did Park Yeon Jin. But Song Hye Ko was an older actress than them, and the age gap was very obvious. The other girls also looked nothing like their past selves. Not a big issue, but just a hindrance if we want more accuracy of the casting. I know Song Hye Ko is suppose to play a cold woman who lost all emotions since the bullying, but her face was literally a stone, outside from the one time she (forcibly) laughed. And there was a lot of forced laughter in this show. On the other hand, I really enjoyed watching Jung Sung Il's performance! He plays a stoic guy as well, but I see sooo much expression with every blink and facial movement he makes.

A lot of parts are still confusing to me, but it's great in getting me ready to watch part 2 of the drama. Also, these comments make it seem like this show is a romance drama with the ships. I wish we talked more about the actual things going on, because this drama is a mess.
