​A ruined veil. A bitter betrayal. A contract signed in silk.​On what was supposed to be the grandest high-society wedding of the decade, heiress Clara Montgomery stands before the vanity in an exquisite ivory gown, only to discover a devastating truth minutes before walking down the aisle. Her handsome fiancé, Julian Vance, doesn't love her—he is using her to devour her sick father's shipping empire while carrying on a secret affair with Clara's own half-sister, Vivian.​Rather than fleeing in shame, Clara walks down the aisle of St. Jude’s Cathedral and exposes the betrayal in front of London’s entire elite class, turning her fairy-tale wedding into a public nightmare.​As her world shatters into scandal and financial ruin looms over her family, an unexpected lifeline appears from the shadows: Damian Vance—Julian’s reclusive, dangerous uncle and the true mastermind behind the Vance empire. Cold, powerful, and ruthlessly intelligent, Damian offers Clara a lifeline in the form of a contractual marriage: he will inject half a billion pounds into her family business and help her crush her traitors, in exchange for her helping him secure total control of the Vance board.​Stepping into Damian’s world means entering a game of high-stakes corporate warfare, hidden desires, and unspoken secrets. But as their fake union transforms into an undeniable, dangerous passion, Clara must answer a dangerous question: When playing with fire, how long can a marriage of convenience stay strictly business?

Four years ago, Alexander Vance was convicted for a high-profile corporate murder he didn’t commit—framed by the very family he spent his life protecting. Fresh out of prison with a reconstructed identity, an empire restored through shadow investments, and a heart hardened into cold steel, Alexander returns with a singular goal: ruthless, calculated revenge.​His prime target? Sienna Thorne—the sharp, fiercely independent, but financially cornered interior architect who happens to be the daughter of the man who sold him out to the police.​When Sienna’s family firm faces imminent bankruptcy due to a string of suspicious scandals, a mysterious billionaire stepping in as their sole investor seems like a miracle. But Alexander’s rescue comes with a sinister, non-negotiable clause. He will clear her family's crushing debts and protect them from underground loan sharks on one condition:Sienna must move into his isolated cliffside estate and act as his devoted partner for exactly 100 days. ​For Sienna, it is an unbearable prison term with a man whose intense, dark gaze makes her skin burn and her breath hitch. She vows to survive the hundred days without letting him break her spirit. For Alexander, it is supposed to be the ultimate weapon—ruining his enemy's daughter by making her fall for him, only to destroy her on the 100th day.​However, as the storm clouds gather over the estate, hidden cameras whisper in the walls, and deadly threats from Alexander's past resurface, the lines between hatred, obsession, and genuine passion begin to blur. Every glance turns into a battlefield; every touch becomes a dangerous gamble.​With the clock ticking down to Day 100, both must face a terrifying reality: What happens when the revenge contract ends, but the obsession has just begun?
