It really wasn't bad, but it starts AFTER they became a couple, while most stories focus on HOW people become a couple, so we miss out on a lot.
Also the English title (Our Teachers are Dating!) is misleading, it makes you think the story will be told from the students perspective or at the very least it would involve them often, but only 1 maybe 2 chapters involve them (the Japanese title is fine).
It's also a bit too sweet and fluffy, while that is nice once in a while, it makes it feel artificial/unrealistic, I mean there is not a single person that is against lesbianism, and while I don't want there to be such people, there should at least be some who don't care.
And there are also very few men and almost no straight women either and everybody is very supportive of their relationship, there is absolutely no drama either, no rivals, no arguments, nothing. It's overly sweet, but at the same time the story isn't long or deep enough and there isn't enough character development to justify the mushy stuff they and the author say at the end, so the ending was predictable and kinda boring.
I suppose Asuka's parents were added to fix that as they did manage to trigger me quite a bit, I mean Asuka brings home her lover and announces their marriage but they instead immediately tell her to reconsider because if she took over the family business there would be plenty of men to make her happy ... like WTF ? they didn't even seem to know that their daughter was a lesbian and they supposedly only want her to be happy, but they recommend she gives up the job she loves and seek happiness in the family business with some random person who might not even come and who is the wrong gender ? that's the most absurd thing they could have said and then they instantly fix their ways, get rid of their bitter stubbornness and do a complete 180 after Asuka and Saki say how they love each other in a few short and simple words...?
While there was nudity, it was limited to breasts and nipples and the author clearly doesn't draw hentai mangas as the designs weren't all that good. The overall art wasn't anything special either, but also nothing worth complaining about.
