The Divine Doctor’s Legitimate Daughter: The Regent Prince Dotes on Her

What? I've transmigrated? And into a corpse that isn't even properly clothed? Even as a corpse, she could hear someone say, “That beggar did a good job, but I didn't expect him to defile you. I never thought he'd kill you outright... Now I can become the Crown Princess in broad daylight!” Then, after transmigrating, the System issued her a mission: if she wanted to return to the modern world, she had to win a man's heart. Just as she was about to succeed, the System's progress stopped moving... Only then did she discover that someone else looked exactly like the man she was supposed to seduce. Were they twins? No, that couldn't be right. They didn't even know each other. So what was their relationship? Did she have to win his heart too to get the System working again? No way! She couldn't do that!
