I've Been Coveting My Brother-in-Law for Ages

This story is also known as I Seized My Brother-in-Law At first, he was the Princess Royal's fiance. The Xie clan of the capital had been a distinguished family for generations. And Xie Chen, the eldest son of the Xie family, was as refined and noble as the moonlight. I was always at my elder sister's side, lowering myself and catering to her, just so I could see him a few more times. In the palace's splendid halls, I shelled lotus seeds, my eyes always straying toward the room beyond. Through the delicate bead curtain, I clearly saw Xie Chen raise his hand to tuck a loose strand of hair behind my sister's ear. He smiled so tenderly. In that moment, my heart tasted even more bitter than the lotus hearts I had peeled. I buried such shameful feelings deep within me for a long time. Until The Xie family was accused of treason. Xie Chen was stripped of his office, thrown into prison, and sentenced to die. That night, a torrential rain fell. My elder sister stayed behind closed doors, vowing to sever all ties with Xie Chen. I, meanwhile, dressed in black and broke into the imperial prison under cover of night. He was no longer the noble man he had once been. His splendid brocade robes were gone, leaving only a ragged prison uniform. Heavy black chains bound his hands and feet, forcing him to kneel on the ground in a wretched state. "Xie Chen," I said with a smile. "Come with me." From then on, you belong to me. * I thought I had rescued a wretched dog. I never expected he was a vicious wolf hiding sharp fangs. Xie Chen never forgot the vengeance he owed for the entire Xie family. His blade eventually tore through the walls of the Great Jing capital. On the day the kingdom fell, my father's and elder sister's heads were hung high. I watched from afar, certain mine would soon be hanging there too. Of course, I wasn't going to sit around and wait for death. I had already packed my things and prepared to flee. But before I could even reach the palace gates, ranks of armored soldiers surrounded me. Before me stood the Emperor's six-horse chariot, its steeds neighing fiercely. Trembling, I fell to my knees. The imperial carriage came to a halt, and a figure in bright yellow robes hurried toward me. The next moment, he seized my wrist and forcefully pulled me into his arms. "Sui Sui." Xie Chen's voice trembled. "Don't abandon me." I froze. Had I... actually succeeded in training a dog? *The main story is told in third person. *Everyone is villainous.
