This was a very fun drama! I enjoy time travel romances such as Live Up to Your Name and Mr. Queen, so this was a nice new drama in the same vein. The main couple's relationship development was really well done, moving from initial dislike to eventually being head over heels for each other. The secondary couple was adorable and hilarious as well! I loved Sa Wol's character. I also really liked Tae Min - I appreciated the development of his relationships with his brother and SIL.

I also liked how Tae Min's mom wasn't pigeonholed into being a complete villain and was portrayed as a three dimensional, believable character. I'm happy that things worked out for her in the end. I wasn't super happy about what happened to the grandpa since it didn't feel completely believable - it was very makjang imo.

Characters aside, I thought that the past and present life's parallel storylines were quite well done. The reveal that the grandpa was the real villain was decently built up. I also liked seeing the differences between the first and last episodes. The lady with mystical powers was a good plot device to tie things together. Finally, Yeon Woo's arrival to New Joseon was absolutely hilarious and really made the first few episodes for me! Dol Se the vacuum deserves an honorable mention for his sacrifice.

Overall, despite the large amount of chaebol infighting, I thought that this was a fantastic drama. The acting was excellent, the romance was sweet, funny, and believable, and the storyline was fun and exciting. The balance between humor and seriousness was also really well done throughout. 9 stars.
