EXIT。

　　All along, I am her residual past, from her leaved the elementary school with me. But it is a little difficult now: I moved about a month ago, and I'm not her neighbor now.

　　In the past, before we leaved, she said that to me" I want to go away from here, my past." 
　　From I saw her first, I have been afraid of that she will leave me someday. And I want together with her forever (Is that too sickening?), but I am also a part of her past.
　　
　　I am a part of her past, but her most past before me, in the times of infant school.
