Fifteen years ago, Gu Chaoyu’s grandmother was brutally killed, and Chaoyu was abducted by human traffickers. Her mute grandfather later found and took in Gu Pancho, a deaf child, and the two have depended on each other ever since. Fifteen years later, Gu Chaoyu is bullied by the arrogant and entitled Gu Pancho. To protect her, her grandfather endures unbearable humiliation and suffering. Everything changes when Gu Chaoyu’s mother suddenly appears, claiming she has been searching for her all these years. But Chaoyu soon discovers the truth: her mother had adopted a boy who resembled her as a replacement — and that boy is none other than Gu Pancho, the very "brother" who wants to humiliate her to death. In that moment, Chaoyu wishes she had never had a mother at all.
