A shy and introverted school girl meets a warm-hearted and uninhibited boy, all kinds of sweet daily life. Suddenly, Duan Ming called her from behind, "Ning Zhiran, come here." After Ning Zhiran heard it, she walked to him with her head lowered and asked, "What's wrong?" Duan Ming threw the vest that he had just taken off to her and said, "Take it." Ning Zhiran accepted it silently, like an angry little daughter-in-law. Duan Ming asked again: "Didn't you buy me water?" Ning Zhiran was surprised and replied: "I... I don't know... You want water." After hearing this, Duan Ming pretended to kick her, and she quickly stepped back and said: "I... I'm going to buy it now."
