Introduction: Summer has arrived suddenly, accompanied by the miserable rainy season. In the long river of time, I am here, waiting for you. If our ending is tragedy, why bother struggling, losing ourselves, and swimming together. Twelve-year-old Zhixia came to the city and searched hard for her brother. After meeting Ning Likong, who changed his life, what is the relationship between his uncle and his aunt? What was the cause of death of my parents? Can the warm boy from that day meet again... If I keep insisting on not giving up, will you stay with me until the sky falls? If I keep gritting my teeth and not letting go, will you stay with me through the destruction of the world, even if I am not that good - Bai Zhixia Maybe you are really like sunshine, simple and direct, a light without any shadow, a light that makes me envious. ——Ning Likong
