英语翻译曾经有一份真挚的爱情摆在我眼前,我没有珍惜,直到失去的时候我才后悔莫急,尘世间最痛苦的事默过于此,如果上天再给我

I once let the truest love slip away from before my eyes,
Only to find myself regretting when it was too late,
No pain in the world comes near to this,
If only God would give me another chance,
I would say to the girl,I love you!
If there had to be a limit of time,
I pray it's ten thousand years.
