Fruits Basket: A New Beginning

(A plot idea) In public, □□; in secret, an exorcist family. Though it is called a family, it consists only of Qian Dai and her mother, Qian Zuxin. After Qian Dai's parents died, only Qian Dai remained, and her younger brother had been adopted. He doesn't know that his family is an exorcist family, nor does he know his true identity. They adopted him to repay a life-saving debt owed to his biological father, Zhang Qi, who had once been extremely close to Qian Dai's father, Qian Tan. She has worked with the Rainbow Children many times and is the only human girl they acknowledge. Not long after, news broke in the □□ world that the rightful heir to the Maria family had died, and that Qian Xuan, her younger brother, would inherit the position. Even the date and location of the formal succession ceremony had been set. There is an unwritten rule in the □□ world: only blood ties count. Qian Dai's younger brother, however, doesn't know that he has no Maria family blood. Theme: Why can't people just talk things out?
