I guess? There are indeed 18-year old high school seniors (I was one for instance), so it’s not like they just made that up to cover their asses or anything. Criticizing the game for male gaze and the usual sexualized female protagonist stuff I can totally see, but I really don’t think it’s specifically meant as pedo-bait.
I don’t think that there’s 18 year old high school students makes the “barely legal” vibes any less. If anything it makes it worse lol
