Looking for a Contemporary Romance Where the Male Lead Becomes a Bodyguard to Repay a Debt of Gratitude

I'm looking for a modern romance novel. The male lead agrees to be the female lead's bodyguard for a while to repay a favor to her father. It's kind of a bickering couple story. I can't find it now. If anyone knows the title, please tell me. Waaaaah.
