Marry My Ex's Billionaire Boss

Chloe signs a marriage contract with Evan, her boss, after her brother arrives from ten years in the future and tells her this marriage already happened. The same brother exposes that her fiancé has been cheating on her, which is what pushes her to accept the arrangement instead of walking away from it. Evan has a reputation at the company for being cold and exacting, the kind of boss who fires people over a missed decimal point, and the contract spells out the terms of the marriage the way a business deal would. Chloe works as an accountant and keeps her job after the wedding, so she and Evan cross paths at the office as well as at home. His family does not take the marriage well. There are dinners where his relatives question her background out loud, and moments where Evan is expected to choose between what the family wants and what he agreed to in the contract. Chloe starts noticing things that don't fit the cold reputation: a birthday she never mentioned that he remembers, an old file with her name on it dated years back. It becomes clear he has been keeping track of her for longer than the contract has existed. The two of them argue, make up, get pulled into schemes by people around them who don't want the marriage to work, and slowly stop treating the arrangement as only paperwork. Chloe's work draws attention on its own merits, separate from her being Evan's wife, and she starts to build a professional standing that isn't tied to him. The brother who started all of this does not explain everything he knows, and some of what he predicted about the next ten years has not happened yet.
