A fire that had been planned for ten years burned down the orphanage and burned away Xu Qingjia's memory before she was seven years old. When she was twenty-five years old, she met Cheng Yi, a cardiac surgeon, on a rainy night - a man who also had flame scars on his wrists, who trapped her with a contract. He collected all her photos and studied every scar on her, but refused to tell the truth about the fire. When his memory gradually recovered, Xu Qingjia discovered that the most painful burn was not from the flames, but from the lies burned by the one he loved deeply.
