Even if you find the lost memory, even if you solve the mystery of life and death, you can't escape what you can't escape, and you can't forget what you can't forget. Zhang Qiling, how can you stay with me forever? You are willing to trade your life for ten years of mine, but you cannot stay by my side. If I can't keep you, then I will follow you all over the world. Even if one day I leave you, you can still remember me from the road we have walked.
