From Death to Power, I Rise

Nathan Miller is the Miller family's long-lost legitimate son who, after being brought back to the wealthy household, faces only cold stares,abuse, and betrayal. His mother shows favoritism, his father remains indifferent, his sister treats him cruelly, and the adopted son Lucas Miller, who usurped his place, frames him at every turn and steals everything—his education, his dreams, even his life. However, fate grants him a second life as Ethan Parker, son of Riverton's wealthiest family. Armed with memories and hatred from his past life, he returns to high society as the Parker heir, vowing to make the Miller family pay!
