Once there was a real love between me and a girl,but i didn't treasure it.
Nothing can describe my regrets when the true love had gone.
There is nothing more painful than losing you.
If I had one more chance,i would like to say 'i love you' to that girl;if i can add a limit to this love,I hope it is a million years.
