One evening three years ago, she came home and found a sunny boy who had appeared in the house, saying he was her younger brother. She couldn't accept it.
He loved her to the point of obsession; she treated him coldly.
Framed, struck with amnesia, and nearly murdered, she was forced out of the Duan family.
Three years later, she returned to the city under a different identity and approached him, intent on taking revenge on the entire Duan family. But she accidentally fell in love with him, and unwittingly uncovered the Duan family's deepest secret.
