When Vivian Ye was a child, she endured brutal beatings from her father, leaving her with a deep-seated hatred for domestic violence. As an adult, she became a skilled and justice-driven karate instructor. However, the trauma from her past made her resistant to marriage, much to the dismay of her grandmother, Eleanor Yuan, who made it her mission to see Vivian married. Under Eleanor’s relentless pressure, Vivian reluctantly agreed to blind dates. But most suitors were intimidated by her profession as a martial arts instructor and quickly backed off. Desperate, Eleanor decided to "refine" Vivian’s dating profile, rebranding her granddaughter as a gentle kindergarten teacher. The change worked instantly—Vivian met the charming and refined veterinarian, Jason Ji. Jason was witty and gentlemanly, with only one flaw: he had been married before and now had a rebellious ten-year-old son, Jay. Despite Jay’s open hostility and defiance, Vivian was moved by Jason’s kindness and decided to marry him. When Jay realized his attempts to sabotage their relationship had failed, he tore up the family’s household registration booklet, forcing Vivian and Jason to postpone their marriage registration. Vivian moved in with the Ji family ahead of the wedding. Jay repeatedly tried to lure her into the basement—a place Jason had strictly forbidden her to enter.

The basement was always damp, cold, and carried a faint scent of blood. Though Vivian nearly stepped inside several times, she always managed to avoid it at the last moment. Frustrated by her resistance, Jay grew increasingly desperate. Hidden in that basement was the darkest, most bloodthirsty desire. Then, during a strange power outage, Vivian was finally led deep into the basement—where she uncovered the horrifying truth about Jason and Jay. The cruelest member of the Ji family wasn’t Jay… it was Jason. The basement was lined with glass jars preserving the delicate hands of countless young women, their beauty frozen in formaldehyde—all to satisfy Jason’s twisted obsession. Jay showed Vivian footage of Jason beating his own mother to death. His ex-wife hadn’t died by suicide out of shame for an affair; she had been murdered by Jason. Jay, who hadn’t inherited his father’s violent nature, had deliberately acted like a spoiled, unruly child to scare away every woman Jason dated—just to protect them from harm. Instead of fleeing, Vivian chose to stay, determined to gather evidence and bring down the Ji family once and for all.
