This is a 10 so far. LOVING IT!! The first episode is gripping. I love Kim Yoo Jung, so I've highly anticipated this series for awhile. She hasn't disappointed. Her character is bold and independent and caring. The ML is so mysterious and cautiously curious about the FL. The secondary cast is great, too. I enjoy seeing Jo Sung Ha play a non villainous role because his character in 100 Days My Prince was irredeemable. Kim Kwang Gyu who plays the headmaster is comic relief...I laughed out loud in his scenes through episode 2. Besides the great cast, the visual effects are so impressive and beautiful. I wished I could wait to binge watch, but I'm too addicted to the cast and story, I'm living for the next episode. So well done.
