我的文采不是很好 但是很认真努力的翻译了 如果没有更好的答案可以参考我的
哈哈 我还是觉得自己的翻译最简介符合原文

My humor is to please you,
but it's not a mission.
Behind that is my bitterness,
what you will never see.

You are trying to forget the past,
I know you kept doing this,
Though it is hard.
So,
I hope you can go on,
go on forgetting the black memory,
and
Shinning your smile to everyone.
If what I did has over your limit,
I will leave,
leave on my own.

For you, I often lost myself,
that is awful.
You think I am kidding?
No,
Just give me one chance,
listen to the voice
from the bottom of my heart,
And you will know
a realistic love

My humor is to please you,but this is not a mission.
Behind the back of my smile is the bitterness that you can't see.

I know you've been trying to forget the past,but it won't be easy.
So I want you to keep on,keep on forgetting the goddamn past.
Face everyone you meet with your smile.
If what I do is beyond your limit,then I'll leave on my own.

For you,sometimes I lost myself.That's too bad.
You think I'm joking?
Then give me a chance to let you know a real me and listen to my heart.
