三年前,我遇见了你,给了你一个承诺；
three year ago,i run into you,and left you a promise
三年后,你会忘记我吗?会忘记那个承诺吗?
three years past,will you still keep me on your mind,also that promise?
三年后,世界将会变成什么样子.
three years later,what is the world going to be?
三年,看似遥远,却又近在咫尺.
three years never been far away,they're beside you and me ..
给点背景资料,你们要离别了,以后再不见了；还是有转机什么的．．．
