From one city to another, time carries people's growth and experiences. It's still the kind of bland story, but this is life: the memoirs of Qi Xiaonian, a bisexual and now lesbian. The pit records her ups and downs from childhood to youth, and does not write about what happened after that, because she only lived so long. The two cities, a thread between them, led to various characters in her 21 years of life. The story of a person and the many people surrounding her, the bitterness, joy, pain, memories, fear and longing, are intertwined into multiple aspects of a person. She seems to be following other people's arrangements and walking her own path. I met someone I couldn't have met, and then fell in love... There was still a long time after that, and the author couldn't guarantee that they would always be together. Maybe that sentence will come true: "I may not be able to be with you, but that doesn't mean I don't love you."
