I'm willing to say that I find this series to be possibly one of the best harem series out there to date. Of course, saying such a bold statement deserves an explanation, so let's get right to it!
Quote from dickegrobe
This one is an extremely cliché harem manga. Actually, it is so cliché that it feels like being made from a manga construction kit (one for beginners at that).
Why yes, the series does follow some clichés and comes to be pretty self-aware of it, as it has various chapters dedicated to different locations/scenarios for the girls to be in (hot springs, dates in town, dates in a park, etc.) However, I'd also disagree with the series being completely clichéd, as if "built from a manga construction kit." Maybe in the beginning that's how the series had been, but I'd give the author a lot of credit to for his overall approach to the series thus far:
An adult guy that's tasked to take care of different monster girls, each and every one of them with different physical conditions + requirements that need to be attended to daily.
Notice how nowhere in the description is "high school" mentioned, which is clearly one of the most typical settings an author could have their story take place. A high school setting would've been incredibly easy to write about for checking off a list of clichés (cough cough Valkyria Nainen Kikan), but no, the author stuck with the characters being adults. Not only that, but the author makes an effort to "world-build" a bit, imagining how the government and different businesses would change themselves to be inclusive to the various different species of monsters. In that regard, it's creative and even sometimes a bit clever for what he manages to come up with.
Another thing to keep in mind is that unlike a majority of harem protagonists that are loved by the ladies as "losers with just a kind personality," the girls in this series actually have believable reasons for loving the protagonist, which maybe has to do with the fact that they're monsters! They hadn't been treated very nicely by some humans in their life, so when they have a young guy that's tasked to take care of their every need, treating them like normal girls with the upmost respect and kindness, it truly makes perfect sense as for why they'd each fall in love with him. When it comes to his reasoning for trying to resist their advances, he's simply hoping to not get in trouble with the government (mainly in the beginning, till things kind of change later on with that issue).
As Nursero, SSJR2, Jandalman, and claudiofd pretty much mentioned, the series is a light-hearted romcom. The author's ballsy enough to alienate some readers of the genre (as xeno01 sums that up), and he's passionate when catering to the (presumably) small demographic of readers that really love true monster girls like he does.

Harem is 99.5% a dead waste of time? Seriously? An entire genre defaults almost any series that has it as a waste of time to it's readers? That's a bit of a slap to the face...
Honestly, it's tough to agree with an opinion that holds such bias as yours. I respect it of course, but I mean for fuck sake, it's a romantic comedy series consisting of light hearted chapters amongst its cast of characters, and you're putting it up against such high standards of 2 award-winning series... That's not to say that good writing shouldn't be strived for; however, it's insulting to basically ignore the particularly interesting + somewhat "unique" ideas I mentioned by the author, where Japanese society alters itself to fit the needs of a vast variety of human/monster hybrids. So please, stop bringing up the "made with a manga construction kit" point that you felt so intent to focus on. I already debunked it (as clearly, there's an enormous disproportion of harem stories with high schoolers compared to ones revolving around adults), and so I'd rather not repeat myself upon that matter.
