However, she has to hide her true identity and pretend to be from Joseon, due to the rumors that the general slaughters Jurchen people, regardless of gender or age. Gyeol on the other hand, cannot drink clear water because of a tragic incident that happened when he was young, and has a lot of enemies who want to kill him.
