The Divine Doctor Is Here, and the Sickly Prince Is a Big Shot!

After working herself to death, she transmigrates into the body of an unfavored legitimate daughter. Her mother is missing, her father ignores her, her stepmother bullies her, her half-sister torments her, and her fiancé is carrying on an affair with that same half-sister? What? As a peerless genius doctor from the 21st century, how could she let anyone bully her? She takes on her stepmother, crushes the scoundrel, and slays her way through one enemy after another. But behind her, a sickly and breathtakingly handsome man complains, “Wife, are you trying to keep your husband all to yourself?”
