Alright, this will be a spoiler free review; so you're going to have to take my word for it, don't bother reading this horrible excuse for a manga. I don't think I've ever felt more like my time was wasted than when I finished the last chapter of this manga.
It's not a novel premise, but at the beginning it lures you in with decent visuals, an amusing protagonist and a surprising amount of tension. Every last positive detail of this story was squandered, just when you're rooting for the protagonist to get credit for his actions from his sister or anyone else, they introduce
a side-character who spends 98% of the time he's around moping, and the rest of it getting credit where the protagonist deserved to.
If there is anything I can say, it's that I genuinely wanted good things to happen for the protagonist. It's pretty rare that they manage to make the perverted guy likable, but absolutely nothing happens. It was deservedly axed, and ended after one of the most uninspired, insipid and generally unrealistic segments I have ever seen in any form of media. This manga may not have been anything special, but it could have been an entertaining story. Instead it ended up being an 80 chapter long pathetic waste of time, and an incredibly frustrating experience.
Admittedly, the scores do not add up; but that's because this manga somehow manages to become far less than the sum of it's parts. This manga could have the best art, a more unique story, and better characters and through what it did with them, it'd still be a 1/10 manga.
Don't waste your time reading this manga, this is garbage unparalleled.
