Not all feelings have their own traces and ups and downs. It is also like the light and continuous relationship between me and Mr. Yangtuo. This is an essay that I have always wanted to do but never put into action. It is used to record every bit of my life with Mr. Yangtuo. We are like all lovers. There will be various struggles, quarrels, and misunderstandings during our relationship, but what is more important is the mutual understanding and tolerance between the two of us.
