Gin no Saji, Sakamichi no Apollon Recommendations
The main character attends school in a unfamiliar rural setting and gradually adjusts to it through the people around him.
Both don't know exactly what they want to do in the future but have expectations from their families.
Both quickly develop a crush on the girl who is sweet and caring to him and a one-sided rivalry with the girl's childhood friend.
Both series are about finding your passion and a sense of belonging; Silver Spoon through agriculture, Sakamichi no Apollon through jazz.
