This drama really could have been a 10/10--the premise of the story is very interesting and has a lot of potential. IU killed it in this. I fell in love with her character. I started watching the episodes at a faster speed when she wasn't on screen. I wish it had focused on her more. The romance in this is seriously disappointing. I was waiting for my happy ending the whole time and once the final episode hit; it was over, and things were left rather open-ended for my tastes. I still do recommend watching this though, as it was a very good experience for me personally. Tears shed, screenshots saved. I watched this all in 2 days and this drama has spiraled me into watching Scarlet Heart Ryeo right after and now I think I may become addicted to KDramas.
