KBS 2TV’s “River Where the Moon Rises” has finally premiered, and it’s full of suspense, astonishing cinematography, political turmoil, and romance. It has all the best parts of a sageuk so far, and even better, it reunites Kim So Hyun and Ji Soo who formerly worked together on the 2016 K-drama “Page Turner.” “River Where the Moon Rises” takes a new twist on the classic Goguryeo folk tale about Princess Pyeonggang (Kim So Hyun) and On Dal (Ji Soo). Although she is born into royalty, Princess Pyeonggang gets separated from the palace and has lived her life as Yeom Ga Jin, a fierce warrior with impressive and lethal fighting skills. She coincidentally runs into the naive and honest On Dal, and the pair fall in love. The drama follows the lengths they will go to protect their love no matter what their fates hold for them.
