When the iron door of the mental hospital was closed, even her biological brother said she was "sick". Half a year later, Xia Tian took Xueqiu's paw and quietly returned to the gorgeous prison. She learned to use their fears as armor - when her foster sister mixed poison into the milk again, she handed it back with a smile; when the nanny tried to abuse the cat, she let the surveillance camera record everything "just right". The slap was loud at the birthday party, but it was the perpetrator himself who shattered the mask. The day the truth was revealed, the perpetrators were imprisoned forever in the lunatic asylum they built with their own hands. Xia Tian finally turned around, saw her brothers' tears of regret, and smiled softly. This time, she signed the discharge certificate for herself.
