Literally on every smut I found there will always that comment that goes like:
"OMG that's rape
" *angry noises*
I mean if you're reading smut/hentai you should know what to expect, pushy ML + timid FL troop is popular among japanese readers so there will always be a 'rapey' scene--
Sex before marriage in Japan is a taboo and thus doesn't come off as something too common, negative even. But sex is still sex so this kind of thing can become an excuse for them to have one.
If you dislike this troop then drop it, I just feel like that type of comment ruins the whole aesthetic and mood sometimes. PLUS this a fiction yall!
