世界很大，世界也很小，希望有一个人，能陪我走遍天涯海角。因为两个人贪恋彼此相处的时光，所以，世界很小，花尽走遍世界的时间，也不够。
The world is big, and small as well. I hope there's one person who could company me to every corner in the world. Two beloved people, and they live every seconds treasurely. Even the time they spend on traveling on planet, but the time is just enough for them, and they will say, why the world is so small.
