As we count down the days until the 100 Days Prince premiere, there's no better time to brush up on the synopsis and characters. Scroll down to reveal new images, teasers, relationship chart, and more!


When crown prince Lee Yool (Do Kyung Soo) loses his memory after a tragic accident, he becomes an ordinary townsperson with a mundane name, Won Deuk. Hong Shim (Nam Ji Hyun) is brilliant enough to run the first detective agency in Joseon, but she’s also the oldest unmarried woman in town. They marry each other without falling in love, because they need each other’s protection. Will Wan Deuk be able to safely return to palace in 100 days to claim to a crown?

Character Analysis:

Won Deuk (Lee Yool)

EXO’s D.O in his first K-drama lead role plays Won Deuk, the crown prince-turned “ordinary townsperson.” He used to be a great archer in the palace but, outside of the palace, he’s got no practical skills to earn money let alone survive. His wife Hong Shim pressures him to do chores around the house, asking him to cut logs, make rope, or take out the trash, but he can’t seem to do anything right.

Hong Shim (Yoon Yi Seo)

Since when did being single became a sin? Hong Shim inadvertently marries Won Deuk to avoid arranged marriage. Won Deuk may be a good-looking guy, but he’s a useless man unskilled to do anything right.

The relationship chart above shows Won Deuk and Hong Shim in the center along with the supporting characters. Challenging Won Deuk and Hong Shim's romance, Jung Jae Yoon (above the couple) takes interest in Hong Shim. The crown princess Kim So Hye (below the couple) holds a love and hate relationship with the crown prince-turned-Won Deuk.
