I'm challenging you to solve the mystery on this movie because it ended up without answers. I have quite an expectation when I watched this because the plot is something interesting, I'm just not sure if my expectations were too high or if the movie didn't really give justice to it or what.

The casts acted so great but the story became more of a confusion to me than curiosity of what's gonna happen next. I just watched along hoping that maybe the end will give me answers but unfortunately, I had more questions. For one, I'm not really familiar about social media culture of Koreans. Second, plot wise I had lots of confusions but the message is there, cyber bullying can be dangerous specially when it meets reality and became a real life bullying. Words can be a knife so we have to be responsible about our words, specially in the internet where people can become who they are not.

At least I can say this is worth a watch if you want mystery films.
