It tells the story of Yang Yuxuan, an ordinary girl with an extraordinary psychology. Her life has undergone earth-shaking changes since she was nine years old. Her strong will did not defeat her. Later, she met Su Mo, who applied his psychological knowledge to Yang Yu. In order to make Yang Yuxuan more dependent on him, Hyun became more and more determined to make Yang Yuxuan more dependent on him. Later, because of their unique torture methods, the two became a ruthless and psychopathic couple that was feared throughout Q City. They were laughing one second and put a knife on each other's neck the next. This is my first time writing a novel. I hope you all will like it.
