This drama is the class female cross dressing as a male to hide from people. Now despite the funny cross dressing, Kim Yoo Jung does the most wonderful job at playing Ra On! The classic tsundere char imo. Her facial expressions, the way she crys. EVERYTHING iwugqkjb. She is great guys. So about the STORY!!!! Park Bo-gum's char is.. well.. very.. CHEESY. In a CUTE WAY. UGH his char is soooooo CHEESY with love. It's so adorable and cute and MY HEART qwjlkbg. HE is perfect. I have never seen a Crown Prince so dreamy. He was able to tug my heart along with him for 18 episodes. I find it so rare that I get to see a drama where the lead male is so cute and cuddly. This alone makes the drama 100% MUST WATCHHHH. I love how in this drama the princess actually starts out as a "bigger" girl. The story of her and Master Jung is cute and cheesy as well. The fact that in the end he thought she looked better before she starved herself to get skinny says it all to me. Side characters in this drama.. HAAA. The Crown Prince has 1 too many BROMANCES if I do say so myself. The best one of all being him and KIM BYUNG. Kim Byung oh KIM BYUNG. A great example of friendship. + he might be the first 97er I have ever fallen for. The Crown Prince & eunuch Jang.. Such a funny thing of loyalty, seeing how jang freaks out every 5 sec. Jinyoung. Oh what can we say about you.. This is Jinyoungs first drama with a lead role and I can say.. he did an absolute superb job. His character is actually quite likeable. But I am more shocked at how good he is at acting. His character is quite a playboy and I think he shows it with his expressions very nice. So really, the main plot imo isn't that GREAT and a little confusing and not really elaborated on but the love plot is great. If you came from somewhere like Nirvana in Fire and you are expecting a thick and juicy plot about rebellions, this might not be the place for you. Overall, This drama is 95% love story focused vs a thick and juicy plot. I actually found the plot around the prime minister to be not so appealing and a bit of a bore. That aside, the queen does an excellent job at portraying a villain. She is legit scary.
