I'm looking for Romantic Dramas with a war background. More romance than war. Please let me know what kind of ending it is. Anything goes.

Ones I know of:

Too Late To Say I Love You

Battle of Changsha

King 2 Hearts. Happy ending. :)
Road No. 1
New Snow Leopard (this one is kinda hard to find, you can only watch this here https://www.youtube.com/playlist?list=PLn2OUPvQDE2...)
Koo Gum (2013 ver) (only available here https://www.youtube.com/playlist?list=PLL2dgKFSnU2... )
Korean Peninsula

I haven't watched any of them so I don't know the ending. I'm pretty sure about the genre tho.
