Plot: A girl has to hide her identity for unknown reason and grew up being a romantic story-teller/cupid to others. She was sold to become a eunuch in the palace and accidentally fell in love with the crown prince. Although there was nothing special to the plot, the first few episodes were actually endearing and fun to watch. Episodes 7 onwards, it became boring and repetitive. The princess and her letter lover were the ones who made me smile, without them on the screen, I was straight-faced or raising my left-eyebrow.

Acting: Park Bo Gum did a good job in acting, while Kim Yoo Jung was initially adorable in the first few episodes, her emotional scenes weren't very good or convincing for me. The rest of the cast were amazing, especially the villains, who kept me annoyed whenever I see their faces. Their acting were more exceptional compared to the main leads.

Music: I don't remember anything extraordinary or catchy music. Sound effects weren't memorable as well.

Rewatch Value: I don't think I'll be rewatching the main lead's scenes. Maybe the love story of Princess Myun Geun and Mr. Jeong Deok Ho, although their first meeting story was still unclear for me. The bromance of Crown Prince and his guard/childhood friend was touching and worth watching.

Overall: 6 stars because I was a bit disappointed after watching this series. I didn't expect much when I started this, but after binge-watching 6 episodes of the series, I got my hopes up, despite the cliché plot, they made the scenes interesting, however, they weren't able to keep the momentum.
