A bride takes her sister's place at the altar, only to uncover the Huo family's century-old secrets of parasitic curses. When the bloodstained wedding bed becomes a battlefield for life and death, how will she use blood as her guide and heart as her blade to tear away the wealthy family's mask of false virtue?
In April, the damp air hangs over Yucheng. Su Ci takes her sister's place as the bride and steps into the Huo family mansion. The gears of fate begin to spin wildly.
A marriage contract, a blood pact, strange wedding customs: behind the Huo family's luxury lie a string of bloody murders. The moment she puts on the jade ring, eerie visions surge over her like a tide: her sister's despair, the bloody glint of a snake-shaped cuff link, the secrets hidden in the old madam's needles. Every clue points to a forbidden truth: a century-old curse sustained by the Huo family's practice of "heart swapping."
By touching objects, she can glimpse the past. This "gift" lets her see a glimmer of truth through the Huo family's fog: her sister's death was no accident, but a meticulously planned murder. Yet as her investigation deepens, Su Ci discovers that a strange power from the Huo family's bloodline flows through her own body. And in the icy eyes of her new husband, Huo Chenzhou, she sees the same eerie blue glow.
Is Huo Chenzhou the turning point in her fate, or a carefully laid trap? As she gradually uncovers the Huo family's secrets, she discovers that her fate has long been entangled with his: shared pain, shared hallucinations, even synchronized heartbeats all point to a horrifying truth. An ancient parasitic art has forcibly bound them together, making them "symbiotic partners."
With parasitic poison, curses, and forbidden love intertwined, Su Ci must choose between the truth and survival. The Huo family's century-old secret is waiting for her to uncover it with her blood.
