Ling Nan and Luo Xian are classmates. As they slowly grow closer, they fall for each other, but a host of circumstances leaves them with nothing but regret.
When Ling Nan turns ten, she gets a little brother. She has complicated feelings about it. After he comes home from the hospital, her family gathers around him, and little by little Ling Nan fades from their sight. No one answers when she speaks, unless she repeats herself. Over time, without realizing it, she gradually develops depression. At the start of high school, she meets an upperclassman named Mu Yun and mistakes him for the person she has always admired from afar. During military training, because Ling Nan is quiet, a group of girls in her class begin bullying her at school and do many cruel things. Then Luo Xian, the one who truly is the person she has always admired, enters her life. With his help and salvation, time and time again, Ling Nan slowly escapes her misery. Two years later, Luo Xian transfers schools, and the news hits Ling Nan like a bolt from the blue. Her dormant depression erupts. Ling Nan begins to save herself. The two keep in touch by messaging, and just as they are about to finally confess their feelings, Ling Nan's confession is rejected. Five years later, they meet again. By then, Ling Nan has become a moderately famous actress, but she has lost the ability to love someone. Luo Xian, meanwhile, is confined to a wheelchair and refuses to see anyone. They become entangled, pulling each other back and forth, only to miss each other once more in the end.
