Don't Hurt Me Anymore, Mr. Gu: Your Wife Is About to Marry Your Nemesis

In her previous life, her adoptive father despised her, her adoptive mother used her, her younger sister ruined her reputation, and her friends stabbed her in the back. Even the husband she had loved for ten years treated her like a pawn, poisoning her so he could marry someone else! After being reborn, she vowed not to waste another life, but to live for herself! Yet her adoptive mother threatened her, her ex-husband blocked her way, and her younger sister was hooked on putting on an act. She'd had enough. If they wouldn't let her enjoy a peaceful life, then she'd flip the table and make sure no one got away unscathed! Just as she rallied her spirits and donned her armor, ready to kill anyone who stood in her way, her usually obsessive, heartless, and willful ex-husband suddenly came crawling back. “Baby, you shouldn't keep that two-faced guy around. Take me with you. I'm quick with a knife.”
