A trailer of the period drama shows King Taejo's next move against Lee Ji-eun a.k.a IU's character. In the video, he announces, "Get rid of Hae Soo. Send her to a place where she can't ever be in contact with the princes."

The promo then takes viewers through a riverside scene, wherein the female lead is being tortured by other workers. The clip also shows Jo Min-ki's character confronting the fourth prince of Goryeo Dynasty. When the King asks his son, "Do you still have feelings for that girl?" he replies, "She is not someone who I can throw away."

The sneak video ends with a shot of So and Wang fighting for the throne after Princess Woo-hee kills the King during a sword dance.
