It is one of the best k-dramas in recent years I feel like the plot of the story is incredible and how she executes her revenge is it's just so satisfying to watch seeing her executing and how she works just a masterpiece. They tried to slow her down but she was playing chess while the others were playing checkers.likee she was always 2 steps ahead of them. She deserved her glory and her bullies got what they deserved. The storyline is wonderful the development of the story is awesome. I love how people were willing to help her to reach her goal and how she was so determined not only to avenge herself but her classmate who was bullied. She is so admirable. I love her character and the development of the story.10/10, would recommend it if you like thrillers and a little bit of cutesy stuff in between, also the acting was impeccable on all parts every one completed their assignment.
