The MC was in I think NYC for the summer and just before she’s about to go home, a little girl in the park asks her to be her nanny. The little girl has a tendency to push a lot of Nannie’s away. The MC agrees and moves in with the little girl and her dad. I’m pretty sure the dad is an architect and hasn’t been in a relationship since his daughters mom passed. I know this isn’t super specific but if anyone knows what story this is, please let me know!
You, Me & Bea?
This definitely has a nanny in a city and she meets the little girl at the park
