So, I was hesitant when I started it and I loved it after the first episode. What I liked most about it was the fact that it wasn't focused on the bullying , at least from outside that's what you think but it was more deeper, the madness, the power, chokehold a child could have over her fellow peers. Since I was following it as it was coming out, I made up speculations about how it could be in the last two episodes and I was still shocked, I enjoyed it, the storyline, the OSTs, they added flavor to the story, the acting was top tier. The main antagonist slayed her part, the main protagonist also slayed her part, I loved her character in the film. she and Ja Eun complemented each other perfectly as friends. She has a sharp mouth and Ja Eun can restrain her, It was beautiful. It showed the importance of friendship, how betrayal can feel and ....nah I enjoyed it. Cheers to the production team for a wonderful drama, I didn't regret it.
