I'm glad I discovered this well into my k-drama watching experience, so that I had enough knowledge in Korean history to not spend the vast majority of the drama going 'uh. Am I supposed to know him?' This was a sweet little story, though the web drama nature of it limits the development of the characters. I love Kim Seul-Gi in every role I've ever seen her play and this one is no exception. She plays a high school senior who is overwhelmed by her upcoming CSATs and yearns to escape. Yoon Doo-Joon plays the king of Joseon and is adorable. This is a time travel drama, where a modern girl is transported back to Joseon and high jinks ensue. The web drama, as mentioned, limits character development because episodes average about 15 minutes a pop. That said, the short episodes make this an easy to consume, pop-corn-esque drama. It was rewarding and I'd recommend it especially if you're looking for something quick.
