A tip to watch this drama: Please remember in every episode that this drama is not a mystery-based drama. It's mainly romance, so don't expect much about the mystery aspect in it. Warning: starting from ep 12, the plot somewhat will go off. It can betray you. But, episode 16 absolutely is your healer.

And here are the pros and cons:
Pros:
- Ko Mun-young's character is so badass, Seo Yeji's acting is powerful! JANG MAN WOL's COMPETITOR!
- Sang Tae's acting is 10/10!!!
- Comedy, yes.
- Legendary filmography
- Beautiful story concept (Using children's book as the main value in a drama? OH YES!!!)
- Episode 16 is super family-friendly. I was teary when watching this episode.
- Support roles make this drama 100000% better!
- Production. Castle in the forest, why not? DEL LUNA's COMPETITOR IS HERE!

Cons:
- The mystery aspect is pretty bad. Imagine, you as a viewer are supposed to think and solve the mystery (about Ko Mun-young's mother and her family story) along with main characters within +- 10 episodes. But, in the end, the antagonist herself appeared out of nowhere, without her true identity being exposed by the main characters. I FELT BETRAYED! Why I had to think hard who and where is Mun-young's mother while she would appear voluntarily?
- Sometimes, romance scenes are too long. This leads to a loose plot. This drama could have a solid plot with a rich aspect if they cut off some unnecessary romance scenes.
- Wasting some characters just to help raising viewer's curiousness about Mun-young's mother. Where did Ok Ran go? Who's the guy that trapped/being held in that place?
- Horror scenes failed! It's scary but it actually makes the plot go off a lot.
- Inconsistency in picking genres. This drama would have been better if they didn't put the mystery aspect that much. Romance-Family-Comedy is more than enough to create touching scenes.
