Damo (2003)

Action, Romance, Mystery. These two dramas have it all. There are fighting sequences, suspense, and not to mention it is interesting to see how old kdramas were filmed. Damo is from 2003 and still holds up, that is if you can see past the exaggerating Crouching Tiger Hidden Dragon combat. Same goes for Chuno, from 2010; although these dramas are fairly old, I still found them enjoyable to watch in 2019.

Both are Joseon period dramas starring Ha Ji Won. Both also happen to be underrated historical dramas of hers in comparison to Empress Ki. I watched both these dramas next to each other and became an instant fan of Ha Ji Won. Who could imagine that the graceful Ji Ni can also be the action queen Chae Ok?

The New Yoshiwara pleasure district, in the twilight years of the Edo Period. Popular prostitute Asagiri will soon be freed from her indentured service. One day at a local festival, she meets young artisan Hanjiro who changes her destiny. Asagiri feels love for the first time in her life, but the history involving Hanjiro's client leads to tragic circumstances.

It also has investigation in the story and Dong Yi also has shrewd investigative skills and relentless drive for justice. She also hide her identity.

A historical drama featuring a star-crossed love triangle starring Ha Ji Won. The stories may be quite different but if you watched Empress Ki or Damo, and liked either of them really well, you must obviously have become a Ha Ji Won fan because since she's the lead of both shows. Therefore, I am recommending Damo to Empress Ki fans and Empress Ki to Damo fans. Both dramas feature Ha Ji Won as an orphan poor girl who has to overcome a lot of trials in her life. Both dramas are also her sageuks where she shows a lot of swordfighting and other action skills. Also in both shows, it appears that she had always loved a man who is kind and caring, but somehow became drawn to another man who she was not supposed to love. The love triangle in both dramas have great effects on Ha Ji Won's character since they both have/gave her something very important to her.
I suggests fans of either dramas watch the other since Ha Ji Won is fantastic in it. Also, because Damo was such a great drama for its time in 2003 but is somehow currently ignored because of so many newer dramas.
