If my girlfriend is japanese,how can i face to my chinese friend,and my family?
I'm a chinese.So i alaways can't face to myself.When i think about the history,i will feel very angry,because my grandfather and grandmother were died from japanese at the second world war.I never think i will love a japanese,but now,i don't know how to talk with my family.
