Sisi and I are pen pals. The process of getting to know each other is very complicated. It is said that it was a dog from the neighbor's house of a classmate's brother's girlfriend's cousin's neighbor. When we were pen pals, we didn't discuss too much. We were just expressing our feelings for those sensational words. In fact, I never expected that we would meet one day in the future! I didn't expect that we would meet one day, and I didn't expect that one day after we met, I showed Sisi the letter she wrote to me, and she realized that I was her pen pal!
