it's because we don't need ADULTS looking at minors doing intimate shit with each other
the logic is literally there and it's just straight up weird to kind of have a fetish or a thing for something like being underage
If this artstyle was more of a 'I twinkify men with cutesy flat chest with a dress in heels' instead of hot makes you drool from your ass because a man is looksmaxxing type of artstyle, everybody would be saying "OH MY GOD SHOTACON"
It's so unnecessary to add ages, and not only that, this is highschool, why are we trying to hit in highschool when it shouldn't be a norm
It's just frustrating for a bunch of readers with a non-incel brain to kinda suck it up when MINORS are not only weird to see in oo la la happy time, it's generally, even with an open mind, a red flag for both to be kind of going to town without either being aged up or at most, romantic slowburn kisses
we don't need more normalizing and content that basically screams 'minors should be in an nsfw setting' like we didn't just get out of japan's 13 and under nsfw works being everywhere (which, unfortunately, still is)

Why are everyone complaining abt the fact that they are minors? Apart from the fact that they are probably almost adults; High schoolers nowdays have probably a more active sex life than adults. Im not normalising but its not that bad, its not like an adult with a minor, they are all minors and not 13
