Thea Vance was held incorrectly from birth and suffered 18 years of agony. After returning home, she was sent to a special training camp for six years to "reform" due to her parents' favoritism and the instigation of their fake daughter Pearl Vance, transforming from a kind girl to a cold and hard avenger. On the first day of returning home, Pearl tried her old trick and was pushed down the stairs. Father slapped Thea angrily. Thea no longer held back, sneered and counterattacked.
