This drama served in every department. Acting, production, ost, story, just everything was outstanding. I was already hyped for this because I loved the Webtoon and because of Bona being the main lead and somehow I was still shocked by how much I loved this. Whoever did the casting I want to thank you because this cast really was able to bring this amazing story to life. I was so pleasantly surprised by the acting in this show, some of the best acting I've seen in a while, even from the rookie actresses. Jang Da-Ah especially shocked me. I was initially worried about her first role being such a huge and complex one but wow she really brought the crazy that was needed for Harin. I love how the cast is full of women. Bona has impressed me in every single role but Suji has to be her best role yet, the way she portrayed this character was spot on and no one could do it as good as she did. I love how Suji isn't perfect and isn't always morally correct, we need more flawed main characters (that are still likable). One detail I loved throughout the story was the similarities the side characters would point out between Suji and Harin, the protagonist and antagonist. These similarities are so important because yes these characters are similar but have completely different end goals. I was also pleasantly surprised that they were so open with Eunjeong and Yerim's story. They made their feelings for each other more explicit than the webtoon. In conclusion, definitely one of my favorite K-Dramas ever and also the K-Drama that got me back into K-Dramas. I hope there will be a season 2 as they did end with a cliffhanger and a new cast member that I am very excited to see added to this already amazing cast.
