人世间最痛苦的事莫过于此

The quote below is extracted from 周星驰的西游记大结局之仙履奇缘. I hope I am not like the lead actor whom regretted on giving up a love bestowed to him by heaven.

曾经有一份真诚的爱情摆在我的面前, 但是我没有珍惜, 等到了失去的时候才后悔莫及, 人世间最痛苦的事莫过于此.

如果上天可以给我一个机会再来一次的话, 我会跟那个女孩说我爱她.

如果非要把这份爱上加上一个期限, 我希望是... 一万年.

Translation:

Once, I do not cherish a sincere love before me. Only to regret when it is lost and the most painful thing on Earth is nothing other than this.

If God can give me a chance, I will tell the girl I love her.

And if I have to put a time limit for our love, I wish it to be 10,000 years.
