Nature Academy was considered to be one of the most prestigious academies in city A. There wasn't a single person in the school who you can call poor. Either they were from prominent families that had a high standing in the city, or they were from well-off families with enough money to sponsor them in the school.
That is why the students in the school were always seen as stoic and snobbish. They always acted as though they were better than other students, especially whenever they were among students from other schools in the same city. They spoke and moved in a haughty and dismissive way that would make anyone think that they were looking down on them.
