Onsaemiro

Hae-Ri Jin is an actress struggling to break through. Confident about an upcoming audition for a historical drama, she visits a museum and encounters an ancient incense burner from the Baekje era. Captivated, she prays for success, unknowingly releasing a deity named Onsaemiro trapped inside. He was sealed there after a past life romance with a Baekje princess, who is now believed to be Hae-Ri Jin's reincarnation.
