Turn My Playboy Dad into an Emperor

In her past life, Serena was the crown prince's daughter, but spent 10 years wandering, unloved and unwanted. She bent over backwards to please her family, only to be shamed, ignored, and betrayed. Even her sister took her life. Now reborn, she picks a new "dad"—the infamous playboy, Prince Quentin. Everyone mocks her choice, but she trains him from scratch until he puts on the dragon robe and becomes the Emperor.
