To be honest, I didn't have much expectations on this manga beyond "this is probably an ecchi harem" but I just finished reading it and I gotta say, this is actually really good!
There's no romance at all, the comedy is great, the jokes are hilarious (at least for me), and both genders could enjoy reading this. It focuses on the girls and I mean just girls cough last chapter spoiler cough and there's no guy butting in their friendship, just pure fun. Of course, just overlook the nudity like I did, and maybe some jokes would be a bit too adult for your taste but I say this was worth my time.
If there will be a sequel, I'd definitely read it!
