[romaji and translation] Days

You are welcome.

To: Delirium-Zer0 and jon the d
Thanks for your suggestions. I change several parts as below, taking them.

Is so precious treasure to me --> Is such a precious treasure to me
So you would surely laugh at me, if you knew it --> So if you knew, you would surely laugh at me
you have precious one --> you have someone precious
your smiling face is telling of it --> it's clear from your smile
Feeling so sad --> Feeling so sad, so sad
(I think "painful" is too strong in nuance as the word for "setsunai".)
If only I think of you --> If I just think of you
Please let me stay loving you --> Please let me keep on loving you

And I have a question.
Some people are suggesting "one and only one wish" instead of "one and onle wish". But actually, I've never seen such a way of writing. Is it common among English speaking people now?
