Navarin Delaunay, a boutique hotel owner, finds herself in a bind when her business faces financial trouble. Enter Loewe Dubois, a charismatic real estate mogul with a proposition: a fake engagement to boost both their profiles. Reluctantly, Navarin agrees, setting strict boundaries for their charade.

As they navigate high-society events in glamorous Paris, the line between pretense and reality blurs. Their undeniable chemistry leaves them struggling with unexpected attraction, culminating in a near-kiss at a charity gala that throws both into emotional turmoil.

A plumbing disaster at Navarin's hotel forces her to stay at Loewe's penthouse, where they discover surprising common ground. Their façade is tested at a tense family brunch, where Loewe's defense of Navarin reveals deeper feelings.

A heartfelt rooftop conversation brings them closer, but just as they begin to acknowledge their true emotions, a journalist threatens to expose their deception.

With the stakes higher than ever, Navarin and Loewe must decide: will they let their arrangement crash and burn, or will they take a chance on turning their fake love into something real? In the City of Love, anything is possible – if they're willing to risk it all.
