King of sloth by Ana Huang

The Setup: Xavier Castillo is a man who has everything—inherited wealth, good looks, charm, and zero ambition. As the heir to a massive empire, he coasts through life on charm and luck, refusing to take anything seriously. He has never had to work for anything, and he has no intention of starting now. But his family has finally had enough: if he doesn't prove he can be responsible, they will cut him off completely .

The Complication: Enter Sloane Kensington, his father's relentless, highly capable, and utterly unimpressed publicist. She is hired for one job: get Xavier to show up on time, act professionally, and stop embarrassing the family name. Sloane has no patience for lazy rich men who coast on their last names. She has worked too hard to build her career to waste it babysitting a billionaire man-child .

The Conflict: Forced into each other's orbits 24/7, their clashes are explosive. Xavier finds Sloane's intensity both infuriating and fascinating—she's the first person who doesn't fall for his charm. Sloane finds him impossible, infuriating, and... surprisingly irresistible. As the lines between professional duty and personal desire blur, they must navigate an opposites-attract relationship where neither is willing to compromise. But when Xavier's secrets threaten to destroy them both, he must decide if he's finally willing to fight for something—and someone—worth more than his comfortable apathy .

Key Themes & Tropes: This is a steamy, slow-burn contemporary romance packed with opposites attract, grumpy/sunshine (with a gender-bent twist), forced proximity, and a hero who must learn that some things are worth the effort of caring .
