To save his multi-billion-dollar inheritance, James Holland has one impossible requirement: get married. With time running out, he turns to the one person he trusts implicitly—his brilliant, unassuming assistant, Phoebe. He proposes a simple business arrangement: a fake engagement in exchange for a life-changing bonus. Phoebe agrees, seeing it as the financial freedom she desperately needs. But as they play house for his family and the public, their staged affection ignites a passion that feels startlingly real. Now, as James battles a jealous ex and family pressure, and Phoebe guards her rapidly softening heart, their paper-thin charade faces its greatest test: what happens when a fake engagement starts to build a very real future?
