Alice wakes up each morning in a completely different marriage — one day she's a doctor's wife with a three-year-old daughter, the next she's the spouse of a fierce police detective in a different apartment, then a billionaire's wife in a lavish estate. Everyone insists this has always been her life, but Alice alone retains all her memories. She realizes she's trapped in countless parallel marriage timelines, each husband growing suspicious of her strangeness. As she learns to exploit resources from each timeline to survive, she uncovers the terrifying truth: a mysterious man named Leo, who has never been her husband in any world, is a cross-dimensional enforcer hunting her relentlessly.
