After Naming the Eldest Princess My Godmother, My Whole Family Regrets It Too Late

In her previous life, Xiao Yuxuan was brought back to the Xiao family. She spent half her life fighting the fake heiress to win back her parents' and three older brothers' affection, only to end up abandoned by everyone and die in misery. Reborn in this life, when her parents showed favoritism, she made the Grand Princess her adoptive mother; when her brothers rejected her, she had her Crown Prince cousin to stand up for her; when the fake heiress played the victim in public and framed and isolated her behind closed doors, Xiao Yuxuan gave her a taste of her own medicine and ground her into the dirt. When the fake heiress's true nature was finally exposed, the Xiao family deeply regretted their actions. They had mistaken a fish eye for a pearl and shut their own daughter and sister out; her parents knelt outside the Grand Princess's residence, weeping and begging her to call them Mom and Dad just one more time; the brothers who had once hated her came to their senses, one after another, crying and begging her to forgive them; but this time, she would never turn back.

His life had always gone smoothly, but at nineteen, something began to weigh on his mind. His aunt, the Grand Princess, had adopted a daughter. His adoptive cousin had parents who didn't care for her and brothers who didn't love her, and an adopted sister who stirred up trouble. Whenever he tried to step in and protect her, he found her either single-handedly taking on a crowd of scholars or crying on cue with Oscar-worthy acting. Before long, he had no chance to play the hero. One day, his cousin finally showed a little girlish exuberance. She stole his liquor and drank herself silly. With bleary eyes, she threw an arm around him and thumped her chest with such force it thundered. “Don't worry, Crown Prince Cousin. With me around, no one can hurt you!” Qi Jun: “...” Had she stolen his line?
