Hae-Ri Jin is an aspiring actress who hasn't had the best of luck. But this time, she has a good feeling about the show she's about to audition for. Since it's a period piece, she decides to stop by a historical museum and comes across a beautiful incense burner from the Baekje era. Mesmerized, she prays for good luck, but little does she know that she has awoken a god named Onsaemiro who was trapped in the incense burner. How was she able to free him? Because she is the reincarnation of a princess of Baekje who was once Onsaemiro's lover...!
