Should also toss in here that the power dynamic of age gap when it's two females is nowhere near the same as an adult male and little girl. Again, I'm not a fan of loli in the first place (I like age gap but with a much higher baseline age) so either way isn't exactly a turn-on, but let's not pretend the two are equivalent.
It's actually a really compelling read if you're not just reading it for the romance portion of it. It's actually a really complex and surprisingly well written story. I really don't like stuff like this normally myself and the fan service was too present (although some of the comedy relating to it was fairly hilarious at times) but I decided to give it a try when I saw how long it was simply because I didn't see why a loli-centric story would be able to go on for that long and I wasn't disappointed. It always feels like it's making some sort of progress and if anything I feel that it might feel a bit better with some extra chapters at the end to flesh out things a little more.
Despite my general distaste for male characters in a lot of mangas Aoki actually ended up being one of my favorite characters in this one. It's really quite interesting to compare him at the start and end of the manga with how much he changes. (For the better too.)
so either way isn't exactly a turn-on, but let's not pretend the two are equivalent.
Definitely not the manga you should read if this is all you're looking for though. While the fan service portion of it might work for those who are actually into loli, the rest of it isn't really like that at all.
