King's Ex. Royal Powers

To escape an arranged marriage, the king needs a fake fiancé. Stat. King Bastien's father locked him into an ironclad betrothal contract with Lady Helena Rey when the two of them were only seven years old. Bas and Helena have never been friends-and not only because she marked their first meeting by dropping a frog down his shirt. He's been unsuccessfully petitioning Parliament to annul the damn contract ever since he took the throne nine years ago.
But with the deadline for officially confirming the engagement rapidly approaching, Bas is getting desperate. Enter commoner Nico Pereira, manager of the Royal Crest Vineyards, who nurses a secret crush on the king. He's at the New Palace to unveil a  wine that's the first joint venture between North and South Abarra. No problem, right? Except Nico has a secret: He has a superpower. Not a very strong superpower, but because powers are a privilege reserved for Royals, it still puts him at risk for arrest and prosecution.
Nico can usually mask his limited foresight gift under the guise of being an incredibly efficient administrator. But when King Bastien asks him to be his fake fiancé? Well. Nico never saw that coming. Nothing if not loyal, Nico accepts the faux-posal, although close proximity to Bastien makes him more than a little. uncomfortable, and the increased scrutiny of government officials threatens to expose his illegal ability.
Good thing this engagement is temporary, because being the king's ex will be a lot less onerous than prison or exile. Or, if the attacks from a shadowy conspiracy continue, than being dead.
