After the Broken Engagement, the Crown Prince Becomes Obsessive and Pursues Me

After transmigrating to ancient times, Xie Ningning became the County Princess of Anyang. She had a hand full of winning cards, including a fiancé she had been betrothed to since childhood! Her fiancé even looked exactly like the man she had loved in her previous life. How wonderful. But it turned out he saw her as a substitute, because he loved someone else! Luckily, she was only using him as a substitute too! What County Princess Xie Ningning never expected, though, was that her fiancé Fu Tingqin, praised by everyone as a paragon in public, was like this in private: He'd grab someone with a vicious look and kill them. And if killing them wasn't enough, he'd gouge out their eyes. If anyone around him disobeyed, he'd whip them and toss them out to feed the dogs. She's scared, she's scared! She was still a decent person with a proper sense of right and wrong, so she thought of breaking off the engagement. Who knew he wouldn't agree? After she finally managed to end it, he grew to hate her. She married someone else, and just two years later, the Fu family rebelled. The cruel and obsessive Fu Tingqin rose to become the crown prince, high above everyone else? Her whole family was thrown into prison, and she became a captive too. What was she going to do? The crown prince was going to take revenge on her! P.S. The male lead is gloomy, obsessive, hot-tempered, and has a double-sided personality. Both leads use the other as a substitute.
