This is a borderline echi comedy centering around student-teacher couples. Sounds fun? Well, it is ... in the beginning. But first things first: Each arc will feature a new soon-to-be couple. So, it's basically a case-of-the-week (couple-of-the-week) kind of thing with no overarching story
apart from most of the characters conveniently knowing each other, which, later on, looks more and more like afterthoughts hot-glued into an existing story .
I really liked it in the beginning. While the echi always seemed a bit forced (as often is the case with echi), there were lots of hilarious situations; there was fluffy romance and quite a bit of feel-good magic. On a sidenote, this isn't your shy oops-here-is-a-little-nip-slip kind of echi manga; instead it favours the more direct tits-in-your-face approach (and quite a few suggestions of vertical lips, too) ... no complaint from me there, either works fine for me.
However, a few dozens of chapters in, the humor is getting weaker and weaker, while the forcedness of the echi situtations becomes just sooooo ridiculous and unbearable. It is really painful to watch. Sometimes I don't even get what the F is happening - like "How, in hell, did this go from there in there ... and why?! Where are the laws of physics when you need them?!"
The recent arc (ass-fixated inventor/science loli and pinki-size weener shouta) is made up of 3/4 shamelessly blatant plot devices and 1/4 crap. Seriously, it's bad. But it already was bad before that, when the author decided to go straight hentai (not as in being overly graphic, but by including ridiculous (and boring) hentai characters) ... and before that, when they went fully cliche with the genius loli teacher coming back from america or somewhere .... uh well. My point is that this manga is waaay past its expiration date, but just keeps dragging on. Might have worked still some time by just delivering slight variations of more-of-the-same, but the author instead chose to one-up each arc (by fuckin up the next one some more).
