If you're looking for a thriller, gore, or action filled drama, then this one might be for you. As someone who didn't read the webtoon, it didn't affect my judgement nor I've expected anything from this, because I have zero knowledge on how things went in the webtoon. In my personal point of view based only on what I've watched, I think this is a good drama. Not a big fan of gore, thriller, horror nor action but I actually liked this. The pace of the story was just perfect, from how they cut each episode to have the audience wanting to watch the next episode immediately, to how impactful each episode was. It has this aspect that keeps me on my seat and totally focused on the things that are happening. For the characters, the actors truly played them well, from the main roles to the supporting roles. (Song Kang was really cute btw). I was hooked because of how well they put into life each of their characters. For the effects and monsters, they were also well done– disgustingly good. Actually I've seen the four actors (Lee Do Hyun, Lee Jin Wook, Song Kang, and Lee Si Young) in Running Man when they appeared to promote the drama and because of that, I got a glimpse of the story. Basically humans become monsters when they give in to their desires. That I think is a good life lesson, that we should not let our desires take over and eat us. This drama is basically telling us that we humans are the ones who are making us transform into something else and that's because of our unstoppable greed over something we wanted so bad. I also really like the heartwarming interactions between characters and how they slowly grew to each other, within that 10 episodes. The only reason why I'm giving this a 9 and not a perfect 10 is because I was looking for something else (or Idk if it is more on personal preference) and also because we got that cliffhanger ending. Wishing for a next season because I want to see more of this. Overall, I really like this drama and it is one of those which is perfect to binge watch when you're up for a genre of this type.
