Damn, I think I got something in my eye... I can only use the Swedish word vemod to describe this; that nostalgic feeling when you're both happy and yet a bit sad at the same time.
3/4 survived the war. The girl in braids is not only holding her dead friend's picture, but her diploma as well. Seems she accepted her friend's diploma for her during the ceremony. Posthumous graduation... As if it wasn't already sad.
