For five years, Shu Wan was Ji Sihan’s hidden woman—his private habit, his signed-and-silenced “exclusive.” Then he ends it with one sentence: “Contract terminated.” She laughs it off. Because she can’t tell him the truth: three months left to live. And the punchline is cruel—his fiancée returns. Ning Wan. His childhood “white moonlight.” The woman Shu Wan was born to imitate. As her heart fails, a predator closes in. Lin Zechen threatens the only family she has—her orphanage sister, Qiao Shanshan—forcing Shu Wan to endure humiliation just to keep Shanshan safe. Then a masked man appears. He calls himself Mr. Ye—brutal, possessive, and always one step ahead. He saves her… the way a hunter claims prey. And the man who discarded her? Ji Sihan starts to change—too late, too fierce, too desperate. He hunts for a matching heart, wipes blood from her skin, and promises: “I will save you.” But can love that arrives after the knife ever feel like love? With three months to breathe, one wedding to protect, two men from the past returning, and one masked obsession tightening in the dark— Shu Wan must decide: who deserves her last heartbeat.
