When I was young, I couldn't imagine how to live in a world without you. Later, you said that no one in this world can live without you. You see, I have gotten used to it over the years. Without you, it is not that good or that bad. I thought you were the most beautiful spring in my memory. It is the yesterday that I can never get back. But thank you for coming back. As long as you come back, don't move, I can walk towards you.
