Reborn Alongside My Scumbag Ex-Husband, I Became His Sister-in-Law

[A toxic couple both reborn + sisters marry brothers] In her previous life, Song Xizhi married the spineless younger brother, while her stepsister, Song Ruo'an, married the elder brother, a mighty general. Who could have imagined that General He Jingyan would be gravely wounded on the battlefield and reduced to a living corpse, while the useless He Yunce she married, thanks to all the painstaking groundwork she laid for him, rose to bear the weight of the marquisate and reached the highest ranks of the court? Yet her timid husband carried on a secret affair with her stepsister, who refused to settle for a lonely life, leaving Song Xizhi to endure thirty years of a loveless marriage before dying in bitter resentment. On her wedding night, Song Xizhi was reborn. This time, she went along with the plan and married He Jingyan, the living corpse. But who knew that this living corpse would be so strong and gallant? She wouldn’t have to endure a loveless marriage after all! …The moment He Yunce opened his eyes, he realized he had been reborn on his wedding night. In his previous life, he held power over the court and had children and grandchildren all around him. He lacked for nothing. All he wanted was to climb to the top again, just as he had before, and spend his life with his beloved, Song Ruo'an. As for the wicked and cunning Song Xizhi, he would divorce her right there on their wedding night! But for some reason, things unfolded very differently in this life. Once he left the wicked Song Xizhi, his career stopped flourishing, his wishes stopped coming true, and he lost the easy popularity everyone had envied. Even his beloved seemed to be showing him her true fangs…
