The title "A Frozen Flower" is derived from a Goryeo-era song depicting illicit relationships, symbolizing a beauty that is preserved but ultimately fragile and doomed to shatter. Director Yoo Ha uses lush cinematography and a vivid color palette—rich reds, purples, and golds—to underscore the internal emotional turbulence of the palace.

: To protect the independence of Goryeo, the King makes a desperate decision: he orders Hong-rim to take his place in the Queen's bed to conceive a child.

Loosely based on the reign of King Gongmin of Goryeo.
