I like a classic quotation from Stephen Chow's movie "Journey to the West": "There was once a sincere love in front of me, but I didn't cherish it. I regretted it only when I lost it. The most beautiful love in the world." Nothing is more painful than this.

If God can give me a chance again, I will tell this girl that I love her. If I have to add a time limit to this love, I hope it will be ten thousand years."
