=> slave characters play important roles in both dramas

=> sageuk set in King Injo's reign
=> action packed kdramas (expect many fights and martial arts scenes) starring actors who are considered sageuk kings and have also played Wang So (Lee Joon Gi of Iljimae played Wang So in Moon lovers while Jang Hyuk did in Shine or Go Crazy)
=> female lead is demure and a beauty (trivia: Iljimae female lead Han Hyo Joo was actually considered for Lee Da Hae's Chuno role).
=> male lead and female lead knew each other in the past, however it takes many episodes before they meet again
