Transmigrated as the Ghost-Controlling Mad Concubine

What? She was already betrothed? Hmph, she had no interest in being an Imperial Concubine. But how could this be? Before she even had the chance to cancel her engagement, she was ensnared by a great rogue who stole her first kiss, seized her freedom, and eventually even occupied her bed. Fine, anyway, that bed was big enough, so it didn't matter if she shared half of it with him; she even got a free, costless body pillow out of the deal. However... why on earth was he her future brother-in-law? Heavens, this time, she was doomed. 【Yi Jingyang: Yue'er, you are like a kind of poison. Once tasted, one can never quit. Let me willingly succumb to the poison, without regret for a lifetime. 】 【Yi Jingyu: Yue'er, if time could turn back once more, I would still choose to fall in love with you, without grievance or regret. 】 【Qi Yalin: One step too late, and a lifetime is missed. Yueyue, if there is a next life, I will definitely not miss you again. I will love you without regret. 】
