WOW is all I can say for this Kdrama. The acting, the writing, the production, the cinematography was just WOW. Amazing job to the entire cast and crew. Song Hye-kyo has proved once again why she is a famous actress of Kdramas, love how her character could show so many emotions without actually showing them. This series is quite good for binge watching, as you'll get hooked on the first episode.

The story of a woman who suffered severe school violence in high school and also how she's risking her life to complete her revenge. The plot is really good and the characters are well portrayed. One of the best dramas I've watched, as the message behind it is so real and affects a lot of peoples lives both childhood and adulthood. The bullies must be taught a lesson. Stop school violence and give others a chance. Some people try to play God and make sure others will never smile. Trauma us also heavily focused on this show. I can't wait till season 2 comes out!
