The title of the book "01 to 100" is taken from the suffixes of the girl Jiaolin and the boy Yunyi respectively, symbolizing that their relationship starts from zero and ends at one hundred. It also expresses the blessing that the two of them can stay together and grow old together. Liking someone is not about piling up feelings with sweet words. Only by sincere and down-to-earth dedication can the foundation of the relationship be solid and the future happiness will be long-lasting. If I love you, I will give everything to be with you. If I hold you back, I will run faster, just to be able to stand by your side for a longer time, to accompany you to watch the sun rise in the east and set in the west, watch the water flow, watch the flowers bloom and fall, and the green mountains remain the same. At the end, I can lean on your no longer strong arms, grinning with almost all my teeth and say to you, "Look, I knew I was the one who could accompany you to the end."
