This drama is about a modern day girl who travels to her novel but has to change the ending of her original story where the villain wins (and in the process totally falls in love with him). At first glance this drama to me looked like a typical light-hearted transmigration novel with not much substance. But I was pleasantly surprised. The main plot of the drama is solving complex murder cases which are all related to the main characters. These cases and the mystery around them truly elevated the plot and kept me engaged until the end. The fact that the female lead was changing her novel story from the inside provided great character development, especially for the male lead. I truly feel like if the drama had a more famous cast, it would have become a hit. Regardless of that, all the actors did a good job.

However, I do have mixed feelings about this drama or rather the ending of it. I loved the plot, characters and how everything was executed until the final episode. I didn’t have any expectations about the ending and yet somehow I felt dissatisfied. In my head I kept thinking “Is that it…?”. The ending made sense which is important but at the same time I wasn’t happy with how the story wrapped up for the characters and couples. I just needed something more and the fact that it kind of has a happy ending but it’s not really happy, doesn't sit well with me.

POSITIVE:
- Male lead is an actual villain. His personality doesn’t drastically change from a bad guy to a total sweetheart. He stays true to his villain personality however his perspective changes. I truly appreciated how he was written and his character development was perfect.
- Engaging crime investigation cases that directly connect to the characters and don’t feel like side stories/fillers.
- Great mix of comedy, romance with mystery and suspense.
- Slow burn romance.
- No love triangles. Despite the male and second male lead both liking the female lead, there was no stupid drama about it.
- Awesome plot twists. The story takes unexpected turns and always surprises you.
- Side couple (Princess and Medicine guy) became my favourite. Their story could seriously be a separate mini drama because it’s THAT good.
- Real villain is well written. Most villains in cdramas are kind of meh but this one here was an actual threat which I appreciated.
- Supporting cast and the side couples are fun to watch.
- Revenge plot done well.
- Awesome OST (I never skipped the opening and closing credits).

NEGATIVE:
- Annoying mother character that made my blood boil like crazy. I had to fast forward through all of her scenes because I literally couldn’t stand her squeaky voice and ridiculous mannerisms. Thankfully she is gone about halfway through the drama so I didn’t have to suffer till the end.
- Unsatisfying ending. As mentioned above, I didn’t like the final episode and how the story wrapped up for the characters and couples.
- Side couple (the original male and female lead in the novel story) was not executed well. Instead of focusing his story on falling in love with his girl, he was turned into a second male lead that liked the female lead. Their relationship felt quite one-sided all the time.

OVERALL:
If you are looking for a transmigration drama with murder crimes as a main plot and romance on the side, where the male lead is a very cool and sexy villain, watch this drama.
