The beginning of a single story

Natsu Dragneel is a single dad. He lost his wife at the birth of his only son, Happy Dragneel. Five years later, when he moves back to his hometown for his job, he meets a girl named Juvia. The colour of her hair exactly matches the colour of his deceased wife and he falls in love with her over time. She becomes an important part in Happy's life when Natsu finally takes the big step and confesses to her.
Will she accept his feeling or break his heart again?

This is an AU; no magic will be involved here (and that truly is a first for books written by me)
