@Logic : Moreover, all of Team Chitose members excluding Yua, are all in sports club. Excluding Yuuko who is in tennis club, all are in competitive team sports club, adding the image of being muscle-brained rather than the book reading intellectuals.
The characters in most light novels are usually go home club, or the smarter kinds are in literature club.
With prejudice, it’s probably because the big target market are those uncomfortable with loud way of interaction with many people.
Oregairu for example, is said to target the 捻くれ segment, cynical.
People likes confirmation, a show that their way of life is not wrong, someone to confide their doubt if their current way of life is right while they look and compare themselves to those people playing outside under the sun; or even just telling them their political view is correct along with arming them with armaments of arguments to quote (how there are news outlets for each political views).
The author seems to put a lot of the common stereotypes in volume 1 to break in, presenting a familiar image of those normies in their strong, confident, shallow, loud, and enjoy oppressing those weaker than them, but also lay down the foundation about how they have their own struggle in that way of life they choose.
After that, there’s no more need to keep repeating the ugly side. They leave that hideous outfit in the trash and the characters starts saying it loudly, “this is me”
