Three years ago, she begged Lin Yuan in the rain to save her family. The Lin family used all their strength to plead with His Majesty to exempt her family from punishment. She vowed to perform meritorious service on the battlefield, so Lin Yuan used the prince's help to plan for her! The world only knows that Lin Yuan is just a playboy who plays tricks on cats and birds, but they don't know that all her war preparation needs in the past three years were earned by him through these shameless means! She enjoyed everything he had, but three years later, she came back victorious and wanted to break off her engagement with Lin Yuan! Just to leave her lover innocent!

Lin Yuan turned around, not only wanting to take back everything he had done for her, but also wanting to become the king of the whole world!
