Very similar in all aspects:
- Goryeo under Yuan rule
- Yuan Prince/King
- Love rivalry between 2 male leads
- Physically strong female lead that gradually becomes entangled in romance and politics
- Serious plot
Both take place in Goryeo and have a love story. Hong Jong Hyun plays a main charater in both. In SHR, he plays an evil brother plotting to take the throne. TKL, he plays Crown Prince's best friend. The locations in both shows are extremely beautiful.
