Regarding the phrase - Rika got carried away with social networks, and it looks dangerous.
This moment, as it seems to me, could indirectly connect her to Shiho, since it was she who hinted at this in the first chapter. I don’t mean that Shiho is involved in the activity itself, only that it aligns with what I had already assumed.
Misato could have done what Sousuke himself should have done long before the events of the manga - talk to his own daughter.
This could be quite an instructive story about children meeting people on the internet, shown from the perspective of an adult (Misato).
If we assume this is the case, then Misato’s awareness of the situation in the Yamada family looks fairly logical, and it is also obvious that she cannot know more than Shiho herself knows.
As for Rika’s sexual preferences, we don’t really know much about them - perhaps fortunately.
This issue is partially touched upon in Rika’s monologues during the bar-related events.
In them, Rika mostly talks about enjoying experimentation in directing - with angles and so on. But personally (based on my own experience), I can’t say that at least the poses in those videos would seem interesting or engaging to me on their own.
After all, the creators of Momonga are trying to compete with an entire industry, not to shock an innocent spouse (Sousuke), whom this really could surprise.
In particular, the Momonga channel format is POV.
This is a fairly popular genre, but on the other hand it greatly limits the process and narrows the choice of poses. Quite good options together with NTR could have worked if the actress’s face had been visible.
In this situation everything looks rather poor to me, and for some reason the camera was never handed to the woman during filming, which also makes it very monotonous. Alternatively, perhaps the actor was not supposed to be shown even in a mask for some reason.
Regarding Shiratori.
This is quite a complicated point. Shiratori claimed that Rika is well known among producers of disgusting content, but it was never shown on what grounds he concluded this or how they even met in the first place.
Their meetings were purely consultative and only in the form of dialogue. Based on this, the question arises - why did they need to reveal their identities at all, especially in the case of a married woman?
This looks very reckless and does not fit with Rika’s image as a cautious, secretive person.
Yes, of course, they both have leverage over each other; both have something to lose, and moreover, Rika - if we assume it is really her who is filming - is always in a mask.
But in any case, personal acquaintance with him is an incredible risk that, in my view, does not justify the result at all.
If Rika is experienced in production and most likely even more so in content promotion, then her “content” and its sales would be the best advertisement. There was no need for them to meet in person.
I would also like to add my purely personal opinion.
In my view, the number of partners in itself, if we are talking about Rika’s past, does not necessarily lead to some kind of “mastery” in sex.
Pleasure from sexual activity is a rather vague thing, especially if we are talking about Rika’s professional activity.
If we assume that she sold herself, then her task would be to bring the client to a conclusion, which, as far as I remember, usually leads to greater dissatisfaction rather than uncontrollable pleasure.
Those women from this profession whom I knew always needed a “loving” and, most importantly, attentive to her body, relatively constant partner who would truly satisfy her - not so much from the point of view of the mechanics of the process, but in terms of feelings and eroticism.
But this is a very subjective assessment on my part.
Such “mastery” could only stand out in comparison to Sousuke himself, not on its own.
And if we are talking about video production, especially in the limited POV format, then diligence, imagination, and a considerable amount of acting skill are what really matter.
As the teacher Shiratori’s girlfriend said - all women pretend during sex.
And one more point: the absence of questioning not only of Shingo Mori but also of his wife. It is quite strange that a jealous wife did not notice changes in the preferences of her previously “inexperienced” husband until the final events - or did sex simply disappear from their married life?
I really liked this line of thought about Misato and Shiho. The guidance for protection of minors in social network is an interesting topic, albeit somewhat "newer" than it should've been in society as a whole.
For Shiho, is protection from predators and other adults. Rika also used this excuse to hide herself in the family photos. Interestingly, another one to approach this point is...Shingo. As for ch. 59, he made his account in 2011( the UI seems to infer twitter, so the minimal age is 13 years old). In a time without control, how he became addicted, and how it twisted his mind into the final product that we saw.
As for Rika's sexual preference, she only talked to Shiratori about forced intercourse( simulating assault), because it was also appreciated by some women, and it could lead to better engagement.
As for Shiratori himself, about your last point: Advisoring( as a business) is somewhat easy to quantify in improvement. The thing is...how to do that here. Quality of the videos and engagement?
Advertising by itself is no metric, unless the CPM of the media in question is sufficiently tracked. And even that, he must sell his product. So...what does he sell? Videos of his "takings of wifes"? Rika's advisoring in business improvement was about video quality and content only? Advertising and overall strategy? I'd like you to think a little about that...cause this could have an interesting theory of joint-venture, tying Shingo and Momonga, as well as Matsuo Jin.
As for your...other point...
Yes, i did not touch into the subject of how many partners Rika had, because this does not mean experience to her. Is quality over quantity. As for mastery: it's pretty much how to make a man climax faster. Eroticism, touch, movement, kegel training, those are so strong, you will know when she knows and is applying. My main point about this "training" is that, while Rika knows, Shingo is an amateur( and probably, my guess, to last longer. So to add a feeling of authenticity. Even in amateur videos, you know when one person is experienced enough).
Her pleasure, to me, is another topic. We did talk how she could take pleasure from seeing people's marriage and live being destroyed by succumbing to lust, right?
Shingo's point is the easiest: just keep the status quo at bed. Basic positions, more cuddling and the likes. He can fake that. It's not uncommon in cheating stories.
Less sex is also common in marriage, mainly due to stress, tiresome outine and/or bad quality of life. Funny, Shingo was a young father, to have something like that while both he and Mitsuri are so young, really triggers a warning about their married, or couples, life...or simply raises a red flag. Since when did Mitsuri start to get jealous of him? we know she always was due to his
ikemen status, but when did it intensifie?
