After the winter vacation, when school resumed, Wu Hanxing suddenly came to say goodbye to Xiangyu in tears. Hanxing had been at home during the Spring Festival, with Grandma saying she had went back to her hometown in Jiuan. Xiangyu had wondered several times when Hanxing would come back. In her previous life, they had always been together until they were separated during the house moving in their teens. But this life, were they really going to part so early? Hanxing had always lived with her grandmother and her dad, and Xiangyu had never seen Hanxing's mother in either of her lives.
Hanxing told Xiangyu that her parents' relationship was not good, and her mother had gone abroad alone. During the Spring Festival, her mother came back wanting to take her away, but ended up having a big fight with her father, and her mon left unhappily. However, Hanxing's grandmother told her son that a person shouldn't be confined to one place, and it would be a waste to live one's whole life like that. With such a good opportunity to go abroad, why not let Hanxing have a try? Even if you don't go, why confine Hanxing as well? You raised her, so don't you hope for her happiness? When Xiangyu went back home and told her grandmother what Hanxing's grandmother had said, her grandmother agreed, "Dear, in the future, you should also go out and see the world. Even if you go far away, your grandma will still be able to see you! But it doesn't matter, grandma will still be happy for you in her heart, grandma wants you to have achievements, to have such a good opportunity to see the world, just think of it as grandma having seen it." Xiangyu buried her head in her grandmother's embrace, "Grandma, I won't leave you, and you don't leave me."
Hanxing left in the spring, and moss had begun to grow in the corners of the alley. She gave Xiangyu a photo of herself, writing on the back: "Don't forget me." She signed it solemnly, "Your Hanxing." Xiangyu gave Hanxing her book< Andersen's Fairy Tales>, writing in the frontispiece: "The flower that wilts during the day is because it dances at night. Even if we're not together, we can dance, paint, and study well every day, but don't lose spirit. Hanxing, please write to me. Japan is very far away? You have to believe that I will come to see you when I grow up, I will definitely save money to come to see you. Xiangyu." The two little friends hugged each other and cried, and Zhou Siping arrived, and the three of them wiped away their tears together. Xiangyu felt like she was a child again, once again learning to grow up, learning to face farewells, learning to wipe away tears, and learning to live earnestly.
After Hanxing left, Xiangyu began to go to school and come home alone. No one was passing her small notes through the floorboards anymore, and no one was watching over each other, then suddenly burst into laughter. Although she had faced more painful separations in her previous life, this life was the first time she had said goodbye to someone. She seemed even quieter now. Sometimes, when Zhou Siping did homework with her, or read books, drew, or watched cartoons together, it was only Zhou Siping's voice, and Xiangyu would often just smile at him.
Hanxing's letter arrived almost three months later, when the city of Hu was nearing summer, and the streets began to smell of gardenias and orchids, and girls began to wear dresses. Xiangyu and Zhou Siping huddled together, reading the letter which had some Chinese characters, some Japanese, and a sentence in English: "I miss you." There was also a cute Doraemon illustration on the letterhead. Hanxing said that Doraemon could fulfill all your wishes, and if we had a Doraemon door or a time machine, we could see each other whenever we wanted. Hanxing said she was doing fine, and the new friends she had made were all nice, even though she couldn't speak or understand the language, everyone took care of her. But she still missed Xiangyu and Zhou Siping very much. Xiangyu and Zhou Siping wrote back separately, telling Hanxing about school and encouraging her to learn Japanese, and even taught her to be a teacher to teach them. Of course, they also wrote many words of longing. Xiangyu and Zhou Siping went to the post office together to mail their letters, and hoped that Hanxing would receive them soon.
