In the feudal era of North Korea, the dethroned Crown Prince Lee Hyun (played by Ryu Hyeon-woo) is forced into lonely exile by his cruel brother who usurps the throne. Lee Hyun's life is in danger at every moment due to his brother's plan to secure the throne by killing him. Frequently threatened by assassins and other conspiracies, Lee Hyun's only true ally is the loyal and friendly warrior guard, Kim (played by Kim Tae-jin). Meanwhile, modern high school student Eun-ho (played by Joon-hee) loves to paint. In fact, art means everything to him. Eun-ho's mission is to complete a mysterious painting, and he accidentally travels back to the distant past, meeting Lee Hyun. The two begin to form an intimate, romantic, and tender bond. However, when the reigning brother is restless and wants to kill the exiled prince as soon as possible, Eun-ho begins to realize that he may be Lee Hyun's strongest ally and perhaps his only chance of survival. 'Dye' is a 2021 Korean drama directed by Hana.
