male here, the manga isn't nearly as much directed at women as the Josei tag would make one believe, the proper Demographic tag should be "Everyone". Sure, the relevant male characters are "hot guys" (something that Katarina even jokes about), but the female characters are just as attractive and cute. The art style in this manga draws out as much charm as possible and I truly love it.
If you're looking for comedy, there are only few manga in recent history, that made me laugh and grin that much, I can't recommend this enough, it absolutely deserves its high rating.
Katarina is a charming heroine, who attracts every male and female that come in close contact with her, but she's also really dumb and unbelievably dense, however that's surprisingly not bad, because it's very well executed in a hilarious way.
The main characters (and even many side characters) never feel bland, they have or develop a fleshed out personality, which is also thanks to Katarina, since her "unique" behaviour lets every character show their true potential as they figure out how to deal with her or their rivals.
