The leaf fall of every tree is the metabolism, and the withering of every flower is the end of life. Every passing year is our growth. I have thought countless times that if my parents had not met for the first time, had not known each other for the second time, and had not known each other countless times, would I still have been born in this world full of chance, and would there have been subsequent encounters and partings. I don't know whether I should regret my birth or my life. But sometimes I think that I am glad that I came to this world and met you.
