The story is written in the first person.
During the summer vacation of my third year in college, I went to Hong Kong to study because of my youthful confusion. I then returned to Shenzhen and after spending time with my cousin Zhuzi, whom I had not seen for many years, I developed a secret crush on her. We gradually made a five-year appointment with hope. However, family misfortune, social turmoil, sudden changes, and human struggles made Zhuzi's spirit tortured, and he finally died in depression. Zhuzi has always longed for a place where inexplicable desires will not breed - the city of Yumiyiyi. I took her long-cherished wish on the road and embarked on a journey of self-growth while meeting all kinds of people and recalling my moments with bamboo.
