You once said: "The world is so small, let's go round and round, but fortunately we will never pass each other, and we will never look back. I want to cook delicious meals and steal your stomach, and you will tell jokes for a lifetime until I laugh. When I am old, I comb my white hair and stroke my wrinkles, and then sit in a rocking chair and chat slowly." But in the end we are still not together.
