A fainting spell on a rainy night revealed the biggest secret of Su Wanqing's life experience: the perfect life she was so proud of was actually a fake stolen from another girl's life. Lin Xiaoxiao, who was struggling to survive in the slums, was involved in the whirlpool because of a yellowed photo, and found that she was the real victim of the baby transfer case. As the two accidentally trigger the "pain empathy" ability, a shocking conspiracy that has been hidden for twenty years comes to light - they are deliberately cultivated "mirror experiment subjects", carrying the ambition of a scientific research institution to break through the limits of mankind. When the gentle fiancé bares his fangs and the loving adoptive father turns into an executioner, the pair of girls with a shared destiny must complete a desperate counterattack in the web of lies: use the enemy's technology to destroy their empire, temper each other's pain into armor, and finally stand at the top of the genetic chain to rewrite the rules. This is not a simple stand-in literature, but a revolution in self-awareness. How do you prove "I am who I am" when everyone tells you "who you are supposed to be"?
