I'll be it, the show is a hentai but it does its jobs perfectly than most of other animes in their own domains. No bullshit complex story, no side characters, gets to the point, no repeated scenes or frames, no skippable content. It gives you exactly what you want in the right dose. Not too much, not too little, just the right amount. Pure efficient use of resourses. Quality over quantity.
If you are still looking for something or anything wrong, then that might mostly be with you for watching this in the first place. I know you will agree to that. XD
