Well, the last episode plays out as what's recorded in history except for the exact method of it. Lelang is overrun by hungry Koreans thanks to the treason of Princess of Lelang. Lelang citizens of Chinese ethnicity(said to be 50% of population in previous episodes) flee back to mainland China during the course of invasion while those of Chosun ethnicity stay on to fight the resistance following the brutal prosecution by the evil Korean king(This is the same historical king played by Song Il Gook in The Country of Wind) that cost the life of the King of Lelang(Slain by Hodong) and the Princess of Lelang(Stoned to death by population for her treason). The regrouped resistance wages one final battle against Koreans, and is defeated and doomed to last man. Princess Jamyung lures Prince Hodong for a duel, stabs him, then they forgive each other and confess they still love each other. When Hodong's men arrive at the duel site, Hodong draws his sword and run it through Jamyung and himself(similar to double suicide ending in movie BiChunMoo and the Chinese movie Hero starring Jet Lee), promising to meet again in next life. So you have evil queen(Hodong's stepmother) having the last laugh. Actually she was crying as she was finally letting her hatred of Hodong go at the site of Hodong's death. So you can imagine "All the good guys are dead and evil people have the last laugh" kind of ending here.
While this show ended early due to poor ratings, this show had an unusually nice love triangle story unseen in other historical dramas. Chung Kyung Ho's portrayal of Hodong's as a playboy prince who would shake the hearts of two princesses was excellent, unmatched by any other historical dramas. I really don't know why this show bombed, maybe the viewers didn't like two actresses playing the princesss?
