Like many reviewers here said, the show starts out fun and promising. Definitely looking forward to both the ML and FL. I also think the series might have been too long. maybe 24 episodes or less might be better. The shows got more and more draggy as the series went on. About episode 18 onwards the story took a dive. In the last 6 or 8 episodes, it took a further dive in story telling to warrant such a low score in my review. One of the thing I personally hate is normally intelligent characters will suddenly become very dumb or overly trusting for no reason (in fact despite the contrary) just so the plot can happen and have more suffering that seems to be completely unnecessary in the overall story.

SPOILER:
Case in point is when ML was so DEAD sure her friend murders her father. Next few minutes later, she would suddenly trust her out of the blue when the friend claims to know who kill her father. So immediately believing her and sparing her life leads to her being drugged, imprisoned, tortured and the whole part has no or effect to the plot if they were taken out.

Another point that is bad for this show is a "happy" ending is sort of tag on near the end with no explanation and defy logic how the character survived just to have a "happy" ending. That's lazy writing and meanwhile the evil woman in the show is given a good (or better than she deserved) ending.
END SPOILER

This drama was such a wasted opportunity and I don't see any strong rewatch value (except maybe the FL). Stay away from it.
