How should I Call You-
It's just like it's name, how to call the other when circumstances keep them apart.

-When you understood me, but I didn't you,
When I believed you but was killed by you,
When you became me and I became you, I didn't know what should I do....

 Fate played with us,..I again meet you, but now I don't know- how should I call you?

Say, who am I and who are you?

S.N.-- I don't know how the description above is. Accepting all the mistakes these lines above have, I guess these few lines contain my story's preliminary emotions. 

By the way, these lines brought to you by Lu Xian.Many thanks  to my babe~
