Forbidden Hearts

This had all the tropes! Read if you love
- single dad
- small town
- nanny
- age gap

Asher was such a good dad to Olivia, and loves her fiercely. He was hesitant with hiring Phoebe as a nanny, but finding someone fluent in ASL is a challenge in their small town.
Eventually he realized that Phoebe was perfect for his child, and needed more of her.
There was attraction but too many reasons to say they shouldn't pursue a romantic relationship. Her dad is his boss, he's older, she's the nanny, etc etc.

Eventually they cave and agree on a “just for rhe summer” affair.

There is drama with Phoebe's past, but as the two become closer they overcome their struggles and build a solid foundation for their future
