Was there any novel recommendation about a young man from the countryside who had nothing to do and then learned medicine from his father to treat illnesses?

It was modern, but I forgot what its name was. I found many names that had the word 'doctor' in them, but none of them. Probably not. At that time, I just saw a magical part. The protagonist found a magical well and used the water there to water the vegetables. They grew very quickly. The protagonist was in the countryside. Some hooligans often bullied the old and weak. Once, they deliberately said that a girl had ruined their vegetables. In the end, the hooligans made a bet with the male protagonist that if they could not pay up in a day, they would take the girl away.
