The Regent King's Little Scoundrel Consort

Mu Qianyan opens her eyes and discovers she's arrived in another world. She's beautiful and wealthy, doted on by her father and mother, and has a brother who cherishes her. She's basically a rich heiress. She'd planned to laze around, but fate had other ideas. What? Someone says I have to take responsibility? And claims I promised? Her childhood sweetheart shows up: "Yanyan, you promised you'd marry me when we grew up." The Crown Prince raises an eyebrow and says suggestively, "Yanyan, after getting this close, you think you can just wipe your mouth and run?" The desert prince blocks her way: "Yanyan, where are you going? You've stolen our hearts, and now you think you can just slip away?" A certain prince arrives in a towering rage, carrying a huge saber: "What nonsense are you talking about? Yanyan is my future wife. All of you, get out of the way! If you insist on throwing yourselves at her, you'll have to answer to the blade in my hand."
