Quick Transmigration: Yandere, Don't Come Any Closer!

"Money, fame, power—I'll give you everything, Qingqing. Just never leave my side." Dead and desperate, Shen Muqing accepts a shady deal from System 000: one billion yuan to fix doomed romances across multiple worlds. The catch? She's supposed to save the original male leads. The reality? She's liberating heroines from toxic relationships and letting them choose their own happiness—even if it means the "villain" becomes the new hero. But in every world, a dangerously obsessed man emerges, and he won't take no for an answer. World-hopping has never been this thrilling—or this deadly.
