Soo-jung (Gong Seung-yeon) is a conceited actress who believes that status and money can get you anywhere.

She accidentally falls into a time-slip portal and travels to the past, specifically to 6th-century Goguryeo, one of the Three Kingdoms of Korea, while it is under the reign of King Pyeongwon.
