Dont pay attention to ornehx, half of what they say I dont know from god knows where they got it. Story is straightforward? Yes, harem? I didnt notice a harem trope at all, he spends most of his time with one of the "airgirls" and another girl which actually likes him romantically, the rest they just find him interesting. This is NOT a "cute girls doing cute stuff", there are some silly situations sure but nothing that could make you feel annoyed. I was actually disappointed that it was only 12 episodes, if only it had 24-26 episodes then It would've told its story properly with a proper ending, such a pity!
After reading their "recommendation" I was expecting a failure of an anime, but I was surprised to find myself enjoying it and wanting to watch the next episode. Give it a chance, it wont be a complete waste of your time.
