It's a manga that is over the top in the wrong way. The entire comedy routine revolves around the heroine and how she has no mental block about saying perverse stuff and showing off her disgusting sides(provoking reactions from people around her), which seems to be pretty much everything she's got.
While this could've been a good setup for a gag manga, it's done wrong, oh so wrong, here. The girl just feels forced and fake, so does most other characters here. It's over the top in a childish way. The humor is immature and cringeworthy. I can only see children and teenagers laughing at this. It's not even good enough as a timekiller. Because of the horribly poor writing, I can't laugh at anything here, I just facepalmed at everything and I do love proper over-the-top gag comedies. The female makes me feel more disgusted than anything and this is not because of the idea that she's perverse and weird but rather because the writing was so bad that she can't be seen as amusing or interesting, she's just an immature brattish kid with mental issues. If she was actually amusing, she could've been a good character, but alas, she's just cringeworthy, so is the rest of the character cast.
Well, this author has never written any truly good stuff, not even the later works. It's just that stuff such as "Watashi ga Motenai no wa Dou Kangaete mo Omaera ga Warui" happened to speak to many of the more pathetic people out there who can relate to it. I personally couldn't even get through more than a few chapters of that garbage before dropping it in disgust as I couldn't stand how obnoxious and sh'itty the female lead was.
I VERY rarely rate anything at 1/10(just as I almost never rate anything at 10/10), but this was just that bad. There was nothing that made me enjoy it even a little. The only reason I powered through it quickly was because I can quick-read 4 volumes in a hour and had nothing else on hand at that moment. I guess it might be enjoyable for children and teenagers or certain adults that likes childish "humor" like this. Clearly there are some of those in the review section.
