lyrics translation. 'Boku o wasurenaide' by Onitsuka Chihiro

well I must confess I do not understand all the lines here. probably I need to do some research. however, I love the last paragraph...

Ｊａｐａｎｅｓｅ

君のダンスフロアで
鳥のように歌うこと
それが君のためにできること
どうか忘れないでね
僕を忘れないでね

褪せた日記帳に
印をつけること
きっと君のためにできること
どうか忘れないでね
僕を忘れないでね

果てた海の底で
宝石を見せること
いつか君のためにできること
どうか忘れないでね
僕を忘れないでね

寂しいその気持ちが
今も胸にあるなら
全部食べてあげよう
どうか忘れないでね
僕を忘れないでね
今も胸にあるなら
僕を忘れないでね
僕を忘れないでね

Ｔｒａｎｓｌａｔｉｏｎ 

At your dance floor

Singing like a bird

This is a thing that I can do for you

Please do not forget this

Somehow, do not forget me

In the discoloured diary

Making a sign

This is surely a thing that I can do for you

Please do not forget this

Somehow, do not forget me

On the bottom of the dried sea

Showing precious jewels

This is a thing that I will do for you sometime

Please do not forget this

Somehow, do not forget me

If that lonely feeling

Is still in your heart

Let me eat it for you

Please do not forget this

Somehow, do not forget me

If it is still in your heart

Somehow, do not forget me

Somehow, do not forget me
