So it's a fairly typical harem comedy except that the main character has a vagina
Just call it yuri harem comedy. Your crude comparison pretty much reduces yuri to 'het, except no one has a penis'.
My point there was that in this specific case it might as well be het, as the MC fill all the functions of typical harem protagonist and even looks pretty androgynous.
Yeah, I feel the same. The MC is a female, but is acting like the typical harem male protagonist. Even the ecchi moments are copy-paste from that genre. The only difference is that MC has no dick. It feels like mangaka wrote a story for male MC but suddenly he got a chance for serialization in Yuri Hime magazine, so all what he need to do was switch the gender of MC and make her look like a tomboy-ish girl.
I have to agree with you guys, this first chapter feels completely by the numbers and frankly, boring (I've read hentai that make a better use of the idea), the art while pleasant to the eye isn't even that special either. Hopefully it will do something to truly stand out among the genre on the upcoming chapters and will make me change my mind.
