God, tell me about it. I can't stand Spider-Man being a High School student. Tom Holland's one of the only guys in the MCU I find attractive, so of course they make the character he plays underage. Because why would anyone be attracted to a man who ISN'T a bearded bodybuilder type, right? Everyone knows that people are only ever attracted to one type of man ever.

But hey, at least they aren't sexualising the high school students. Which is more than I can say for a lot of manga. If they want to draw attractive women or men, they can, but why do they feel the need to set everything either in a school or some weird school-proxy? I mean, Jesus, just make them adults, it's not hard.

Free!, My Hero Academia, Full Metal Alchemist, Gundam Wing. They all seem to do it. They could tell the exact same stories with a cast of adults and keep the same designs and voices, but instead they choose to be creepy about it.
