My BDSM Bodyguard Boyfriend Is a Billionaire

Marnie Winters once moved through New York's elite circles as a wealthy heiress, until the night before her wedding, when her fiancé Richard Sullivan and her younger stepsister Amelia engineered her downfall. Stripped of her fortune and reputation and cast out by her family, Marnie finds herself alone on a dark highway, where she meets Rex Sullivan, a retired bodyguard known for vanishing from public life after years of covert operations. He happens to be Richard's uncle, but Marnie sees only an opportunity.

Driven by a thirst for revenge and a way to reclaim her life, Marnie proposes an arrangement to Rex: a physical relationship bound by strict rules, with genuine feelings strictly forbidden. What she doesn't realize is that the man she has made a deal with is far more than he seems. Rex hides a huge secret: he is the unseen billionaire behind Thunder International, the world's leading security corporation. As they keep up the act of being a couple, building a relationship on concealment and mutual calculation, the line between their staged intimacy and real connection begins to dissolve.
