Boys Don't Cry (2008)

The story takes place shortly after the Korean War. It depicts very graphically how difficult survival is for young people left without family or support. The friendship shown here and their devotion to each other is very stirring. There is a lot of good action which keeps up the interest throughout, as well as the uplifting moments where the "kids" help the younger children. This is definitely one of the better Korean movies out there if you are looking for something deeper than a simple rom com.
