Fake Wife, Real Trouble: A Fake Marriage, Enemies to Lovers Romance (Billionaires and their Fake Brides) by Rosalie Ember

Fake Wife, Real Trouble He needed a wife. She needed a freezer. Nobody planned on the rest. The deal was simple: Rosie caters his investor weekend, Alexander gives her kitchen access. One night changes everything, and suddenly the grumpy billionaire who owns her building needs the feisty baker who hates him to play his wife for the cameras — or watch her bakery get swallowed by someone with worse intentions than either of them. Rosie has rules. He has clauses. They have chemistry they're both pretending doesn't exist and an ex-boyfriend circling her business like a very expensive shark. The contract said temporary. Her heart didn't get the memo. Contains: fake marriage, forced proximity, one night stand, grumpy/sunshine, enemies to lovers, and a billionaire who learns that the best thing he ever acquired wasn't a building.
