I read the manga, and while it seems to be a good adaptation of it, I just don't get where a lot of the praise is coming from. It's a charming and wholesome story, but that's about it. I had a good time reading the manga but it baffles me when people call it "genius" or a "masterpiece". Narratively there's not much originality. And though the plot invites many opportunities for humor, I felt disappointed that they kept repackaging the same gag (this doesn't apply to the anime yet). To wrap it up I'll just mention that I don't mind if anyone enjoys the show, and I agree it can be fun to watch if you turn off your brain, but I think people will forget about this anime after a couple years.
