Song Yiyi said: "I am a person who doesn't know how to refuse, and you know it best." Song Yiyi said: "I am very strong, don't worry about me." Song Yiyi also said: "Zhiwei, I like spicy food, but my mother doesn't allow it."... Song Yiyi's story is very short, so short that it feels like it has stopped abruptly. But even such a short story still left an unforgettable impact on Xing Zhiwei. Later, Xing Zhiwei sat on the Hulunbuir grassland, surrounded by laughter, bonfires, singing and dancing. There are still familiar scenes and familiar songs, but there are no longer the same people. Xing Zhiwei said: "Since you won't refuse, I will help you share the burden in the future." Xing Zhiwei said: "I would like you to show your weak side to me."... There are many memories, but they are just memories. The story between them is simple.
