The Temporary Wife

Luca Windsor is convinced he hates the secretary his grandmother assigned him, but he knows he can't function without her either. Valentina is highly professional, and always a step ahead of him. Despite his insistence that he'd never want her, he loses his composure the second his grandmother mentions pairing her up with another man. A dance leads to a kiss, and the lines are blurred.
Except...Luca has always known he'd end up in an arranged marriage, and he knows Valentina isn't on his grandmother's list (or so our silly hero thinks). He attempts to distance himself from her again, but is unable to, going as far as reinforcing a companywide anti-dating policy to keep her from seeing anyone else.
When Valentina experiences a personal crisis, he demands the ultimate price for help he'd, unbeknownst to her, already given her: her hand in marriage.
The two start a marriage of convenience, and along the way, they learn they're better suited than they ever thought possible, leading them to rethink the 3-year timeline they put on their marriage.
