I really loved this drama. It's Cha Eun Woo's best one in my opinion, and I say this as someone who really enjoyed My ID is gangnam beauty and True Beauty.
Cha Eun woo's character is really cute and bubbly, whereas shin se kyeong's is a bit more serious which I love so much because I'm a sucker for relationships where the girl is more dominant.

The love story is cute and I love how prince Yi Rim completely respects her need to work and to be a historian who makes an impact and who tries to stop the corruption. Their chemistry definitely helps as well.

The ending is great too, I feel like I wouldn't have wanted it to end any other way :))
