I do not deserved to be with you
Everything in this world will fade(渐淡、渐消失)， except the smile from you when you turn back

翻译成中文\
我不足以与你相配
这世界什么都会陈旧,除了你回头的微笑

You deserve much better than me.

Everything of this world will get old, except the smile when you turned around.

i am not qualified to be your boyfriend (girlfriend).everything could be outmoded for this word but your smile.

或者

i am not good enough to suit u,evrything can be past except your smile always live in my mind.
这句话的意思是:我不足以与你相配,任何事情多会被遗忘,除了你的笑容一直活在我心中

I am not enough to match with you
What will be obsolete in this world, in addition to your smile back
