After the Male Lead Cheated on Me, I Became His Sister-in-Law

Once someone learns the plot and discovers they're the villain in someone else's story, destined for a tragic end, of course they'll want to divorce their scumbag husband and save themselves. But before Shen Qiqi left, she still wanted to get a little revenge: If I don't trip you up, all those three wasted years of my life will have been for nothing! Much later, the second son of the Qi family had a pile of illegitimate children, poor health, kidney problems, and barely a penny to his name. Suddenly realizing that a first wife was best, he turned over a new leaf and went after his fabulously wealthy wife. But she wouldn't give him the time of day, and his elder brother's gaze had turned strangely unreadable. It made him feel deeply uneasy. Until one day, the marriage certificate he'd forged was exposed, and his “wife” turned out to be his sister-in-law. Qi Yunyi: T_T I regret everything! Qi Chengye: Remember to come to the wedding banquet. Shen Qiqi: Call me Big Sis-in-Law~ Note: One-on-one romance, both leads have only ever been with each other. The scumbag's downfall is thorough. Theme: To love someone else, love yourself first.
