Moonlight Drawn By Clouds. This lovely little gem stars Park Bo Gum as Crown Prince Hyo Myeong and Kim Yoo Jung as Hong Ra On, a young woman who has spent most of her life passing as a boy and ends up, through various bits of misfortune, serving in the palace as a eunuch. Of course, they fall in love. There's also Jung Jin Young as Kim Yoon Sung, former childhood friend of the Crown Prince and hapless second lead who knows the girl's secret before everyone else, and Kwak Dong Yeon as Kim Byung Yeon, also a childhood friend and now the Prince's bodyguard and right hand. It's a historical drama, so politics are everywhere, convoluted, and deadly. Birth secrets sprout like mushrooms after a rain storm. Through it all, Park Bo Gum and Kim Yoo Jung are adorable. It's nice to see Park Bo Gum in something where he's not a sociopath or locked into a limited range of emotion. The story is not ground breaking, covering a lot of common sageuk tropes, but the actors are so delightful it doesn't matter.
