In this series, we follow the celestial Hwanwoong, the 19th king of Goguryeo, on his mission to improve the world. He falls deeply in love with Saeoh and presents her with the sacred joojak necklace. However, Kajin's jealousy grows as Saeoh gives birth to Hwanwoong's son. In a fit of envy, Kajin takes the baby and tragically throws him off a cliff. Believing her child lost, Saeoh is consumed by grief and transforms into the fearsome black joojak, intent on destroying the world. Hwanwoong, the only one capable of stopping her, intervenes. Afterward, Hwanwoong ascends back to the Heavens and foretells that 2000 years hence, the genuine Joo Shin king will descend to Earth. With the aid of the four gods, he will restore Joo Shin to its former glory.
An okay first half followed by a significantly worse second half but that wasn't enough as it fumbled the landing even harder. The drama massively under-delivered on the ending and everything it was building up for 24 episodes. The most laughable aspect of the ending was the antagonist, he was shown as a powerful big threat just to be dealt with in the most comical way possible at the end. The fantasy elements were passable with nothing outrageous other than the messy introduction. I certainly don't miss Bae Yong Joon, kinda under-delivering on his role as the main protagonist. Meanwhile, Lee Ji Ah earlier carrier was much more interesting and enjoyable than her latest roles.
