Similarities:

==> the male lead undergoes training in fighting and martial arts, which are of great help to him in the future as a great leader
==> Yeo Ho Min's characters are very loyal followers to Song Il Gook's characters in both dramas
==> SPOILERS: there is a woman deeply loved by the male lead but he somehow had to end up with another woman (whom he doesn't love as much as the other but she was a good wife for him and is someone he learned to care a lot)
Aside from Song Il Gook and Yeo Ho Min, other actors found in both dramas include Bae Soo Bin and Lee Jae Yong (their characters in one drama are very different from the characters in the other drama)
