People REALLY be bitching about the MC being weak to boobs and not pushing them away, when that's literally the entire premise of the series, and in fact is stated clearly in the name. For those who don't remember, the title is, when translated properly, "I was banished by the big-breasted girls, but even though they told me to come back, it's too late... I'm going back!" indicating his willpower crumbles when big boobs are involved.
Sure, we were told what the premise was, but a lot of people (myself included) were hoping there might be at least
some substance to it. I've certainly seen more overtly sexual manga out there that still present better characters than this.
Ironically, if the author had put
less effort into setting the story and characters up, most of us probably wouldn't be as bothered. Like, I know that if we hadn't had the scene of Shin being haunted by feelings of worthlessness and then overcoming them while fighting that dragon, and hadn't had him look over at the dragon's tooth during the first Sage scene to remind himself that he actually has value as a person, then all the subsequent scenes wouldn't have left such a bad taste in my mouth.
The author did
just enough setup to make us care about seeing Shin do well for himself, and fleshed out the first two girls
just enough to make it obvious that everyone involved would be happier if they just sat down and talked it out (with the key point of
actually letting Shin talk), so now that's tainted all the smut because it's pretty easy to see potential for a
much more interesting manga.
It doesn't help that the smut is boring and repetitive. Honestly, the only reason I'm still reading is to see if the author
somehow manages to pull together something decent out of this.
