In my fantasy happy ending, you unlock a wedding dress and a tuxedo from the shopkeeper, get the creepy merchant to find you the engagement and wedding rings (just for variety) and get the restaurant girl to host the wedding reception, which is attended by those three characters and other townspeople who have come to recognize the adorable, inseparable couple around town. While going through those processes, the MC teaches Sylvia how to read, and she asks if she can look at the medical books in your library "to become a better assistant in your practice". Eventually, she enrolls in nursing school and also, with the MC, starts having fertility treatment. Loving wife and mother, with a career she can feel proud of = <3 <3 <3 .
