Matrimoney

A cash-strapped dog walker agrees to a thirty-day fake engagement with a reckless billionaire who made his name as an underwear model, all to rescue her sister. She expects a purely businesslike arrangement, but sharing a mansion quickly leads to fiery arguments and a pull neither of them planned for. As jealousy flares and their feelings grow, they face a choice between treating their pretend marriage as nothing more than a deal and admitting the real love they have been dodging.
