Oh, come on. Your opinion is as biased as that of those that you call "bawling babies", if your profile picture is any indication. Just because someone doesn't enjoy NTR like you doesn't mean they're infantile.
Now, that aside, Wolf Guy isn't really that interesting of a story. Even if you ignore the rape arc, Wolf Guy still isn't something I'd recommend. In fact, if anything, I reckon that most of Wolf Guy's renown is owed to the rape arc; if it weren't for it, there really wouldn't be anything that would set it apart from all those other beat-em-ups. The story, as a whole, is cliché and somewhat predictable (although there were some relatively interesting twists toward the end). It did have some good and interesting moments, but it's not the kind of story I'll keep thinking back to. It'd be unmemorable, really, were it not for the rape arc. If you're out of anything to read and are looking for something to consume and you don't mind neither NTR not rape, feel free to give it a try; otherwise, I wouldn't really reccomend it. I mean, it's better written than most manga coming out nowadays (especially isekai ones), but then again, that's not really hard to accomplished
Finally, just to wrap up, let me address the rape arc. Usually, I'm against downvoting a story simply because it has rape or NTR. Don't get me wrong; I hate rape and NTR (I'm a vanilla-only kind of guy), but as long as they're not the main focus of the story and actually have a purpose, I can put up with it. In this case, yes, I must admit that there was a purpose to the rape and NTR. It was, like Never_Forever put it, thoughtfully used. It wasn't gratuitous and random like in Gal Cleaning. HOWEVER, that's not to say there was no fanservice in Wolf Guy. A rape scene or chapter would have sufficed. The author dragged it on for fanservice purposes, and that I cannot condone. It was too long and too much detail was put into the art. You could argue that it was to better set the tone and show how depraved the situation the heroine was in was, but that doesn't change the fact that although it, in it's essence, gratuitous, it's unnatural length and excessive detailing most definitely was due to fanservice.
Honestly, I wouldn't read it. Even if you ignore everything I've said above, there's also the fact that the suspension of disbelief that Wolf Guy demands from the reader is too much, considering what it's trying to be. There's no way the protagonist and the antagonist are only fifteen years old. Not with their characters design, not with their personality. Were they adults (university students, for instance), this story would have been many times better.
All in all, if you want something that will give you a good read, look elsewhere. If you don't mind rape and NTR and have nothing else to read, then feel free to give it a try. It's not a good story at all, but it's above-average compared to what's coming out nowadays, so reading it won't be a complete waste of time. In any case, the chapters are short and you can easily read all of it in one sitting. Also, although I have yet to read it, I've heard that one of the author's other stories, Akumetsu, is quite good, so you might want to give it a try.
