Su Xiaoxiao, a stubborn girl with three "little" names hidden in her name, has been suffocated by her single mother since she was a child, but she is holding back a "crazy" energy in her heart. She and her best friend Chen Youyou called themselves the "overlords" on Wutong Street, thinking that they could remain so heartless forever, until Youyou suddenly moved away, and her world suddenly became empty.
Forced to enter the key high school "Ivy League Middle School", she bumped into the prickly Xia Tian - this young man who skipped classes in fights and had wild eyes, but after she blocked his blow, she said "Be my girlfriend" with red eyes. They made a ridiculous bet: She would nod if Xia Tian was admitted to the top fifty of her grade. But youth is never a fairy tale: her best friend turns against her, her family is broken, and a sudden nightmare slams her into the mud.
She fled to Yunxi City, thinking she could erase the past, but she met Xia Tian again when she was most embarrassed, and lost him forever the moment she turned around. When Xia Tian's twin brother appeared with hatred, and when the boy who had misunderstood in childhood reached out again, Su Xiaoxiao understood: there is no perfection in youth, it is just about suffering, missing, and finally learning to get up on your own. Those whom she loved, hated, and disappeared eventually became scars on her chest and medals of growth.
