My Target Was the Crown Prince, but I Accidentally Flirted with the Cold-Faced Prince

[Transmigrate into a book + Pursue the wrong target + The wife-chasing crematorium] The day I transmigrated into the book as the General's legitimate daughter, the System told me: Win over the Crown Prince and have his child, and you can go home. Rumor had it that Crown Prince Xiao Heng was noble and radiant, as gentle as jade. I went to great lengths to get closer to him, step by step. But I pursued the wrong person. He was actually the Crown Prince's own younger brother, Prince Chen! I hurried to set things right, only for him to pin me forcefully in a corner. “Feng Ning, you don't look at Second Brother the way you look at me.” I said I wanted to become empress, and he believed me. Then he turned and left. Later, the emperor died, a new emperor ascended the throne, and my mission failed. The System rebooted: my target had been changed to him. The man I had pushed away with my own hands became my only choice. He gripped my chin, hatred and pain in his eyes. “Will you climb into the bed of whoever becomes emperor? Feng Ning, what do you take me for?” He didn't know that every time I pushed him away, it felt like I was cutting out my own heart. And he had no idea that just as I was finally free to love him without reservation, the countdown to going home had already begun. [Romance-focused. The male lead is chaste; the female lead is not.]
