I have had my best love before, but I didn't treasure her.
曾经有一段真挚的爱情摆在我的面前，我却没有珍惜。
When I lost her, I felt regretful.
直到失去才追悔莫及。
It is the most painful matter in this world.
人世间最大的痛苦莫过于此。

If God can give me another chance, I will say three words to her --- I love you.
如果上天再给我一次机会的话，我一定会对那女孩说三个字：我爱你。
If you have to give a time limit to this love, I hope it is ten thousand years.
如果非要在这段爱情前加个期限的话，我希望是一万年。
