After Rebirth, I Married My Scumbag Ex's Nemesis

In her past life, An Nuan’s naivety led to her tragic death at the hands of her scumbag fiancé and her own family. Given a second chance at life, she wakes up on the eve of her wedding. Armed with the memories of her previous life, she approaches her ex's arch-rival, Ye Jinghuai, with a daring proposal: a marriage of convenience to ruin her enemies. What started as a calculated alliance to tear off the masks of her betrayers soon spirals out of control. In this game of fake marriage, the lines between acting and reality blur—and An Nuan realizes her "nemesis" husband has been playing for real all along.
