Her Heartbeat Hides A Deadly Secret

Perfect love requires pain to leave a mark." When the micro-poisoned needles of the "Eye of the Deep" collar pierce Iris's jugular, a 21-day lethal countdown begins. To the outside world, she is a fragile, bankrupt bride dependent on the brilliant tech oligarch Arthur. But beneath the disguise of a perfect prey lies "Vein"—the dark web’s most elite physiological-control agent. To uncover the truth behind her mentor's death, Iris willingly steps into a lethal fortress rigged with infrared lasers, thermal imaging, and polygraphs. Here, she must survive Arthur’s sick psychological tortures using terrifying diaphragm control and heart-rate manipulation. If that wasn't enough, she must also manage the digitized "Cyber Ghosts" of Arthur's three murdered ex-wives, along with a dead-eyed, inscrutable butler who cares only about his overtime pay. Deceit, venom, and betrayal intertwine. When Arthur believes he has cornered his prey in an isolated island slaughterhouse, Iris finally drops her fragile act. The hunting ground inverts. The real massacre has just begun. From the cliffside estate to a deep-sea dark web fortress, witness how a max-level agent uses extreme violent aesthetics to drag a self-proclaimed "criminal artist" straight down to hell!
