Is misato stupid? If she goes to the police both rika and iwabuchi would be fucked too so she can blackmail rika using that and get away.
I was right about satsuki listening everything from somewhere and she will definitely beat rika.Its quite possible rika doesn't have anything to blackmail misato but only bluffing about it.
What are the chances that she is living in her own home ?
Also,I get the feeling that rika is trying to save misato indirectly using sousuke from iwabuchi but the chances of this happening is very low

A lot of these characters are. Heck, we've been talking about Sousuke not getting a DNA test, making a backup of the SD Card, going to a town he new nothing about( except from old times). Shiratori meeting face to face with Rika and Shingo. Shingo letting himself be filmed while having sex with other women. Even some of Rika's plans work because of the plot itself, not because they were throughot smart themselves.
I'd like to pretend Iwabuchi is a pseudonym, and his ability with spyware would render him immune to getting caught, unless recognized in person.

So… I’m kind of curious about the story, but I also don’t really want to read it all. I’ve read some of the discussions, but they’re kind of confusing, so I was wondering if someone who’s actively reading it could be kind enough to give me a summary of the story so far.

I copy/pasted some info from an old post i made in another thread, but here you go:

Spoiler

• Matsuo Jin owes a huge amount of cash to Rika( 10M Yen), which she lended and saind such a sum wasn't a problem for her;
• We later find out she has more than 80M Yen in a secret bank account;
• She has sex with Sousuke over whos gonna be filming Shiho during the sports festival;
• The next target is Kamizaki, who works in a bank;
• During the sports festival, Sousuke and Akiba find out Kamizaki, as with many other parents, is a victim of Ryouga Shiratori, a teacher at school has sex with wifes, while their husbands film them. All while the 3 wear masks, to hide their faces. This is to give the couples child references, so they can go to better schools;
• He also uploads these videos in the internet, though properly censored;
• Sousuke and Akiba infiltrates this bussiness with the help of Matsuo Jin and his wife, Senna;
• Sousuke and Jin are caught by Kamizaki and his wife( while not reporting this directly to Shiratori), while Senna, who was a bait herself, fails to lure Shiratori;
• While keeping up appearances, so to not raise suspicions, Akiba is approached by Rika, who wishes to talk to her at a later date;
• Jin manages to free himself, but while trying to save Senna, he falls to a trap by Shiratori. Upon the critical moment, the bell rings, and Shiratori is forced to free them;
• With the situation at school coming to an end, Sousuke and Akiba sets a plan to lure Tsutsumi, Shiratori's girlfriend, into helping them;
• She agrees and records a fake sex video with Sousuke( who himself wears a horse mask similar to Shiratori);
• Shiratori breaks and goes looking for Tsutsumi, to learn why she did it;
• Before their talk, Sousuke appears and interrogates him about Rika;
• Turns out Rika is the one who teached Shiratori about this bussiness, never having sex with him, but making sure he understands how to engage on it properly. His teacher;
• He also explains that she is well know in advisoring this bussiness;
• When Sousuke almost gives up, Shiratori explains that the owner of Momonga channel, and probably the guy who had sex with her, is Shingo Mori;
• In a breather, we see Jin, Kamizaki and even Shiratori fixing their relationships( 2 of them having sex with their loved ones);
• On the other hand, when meeting with Akiba, Rika reveals she's pregnant, and wants counceling when dealing with Shiho;
• The phetus is more than 2 months old. And considering Sousuke's and Rika's sexual encounters, while she says they used condoms and she was on the pill, it seems fair to assume it's from her lover. She also does this to keep Akiba away from Sousuke;
• The next plan part is going to a happening bar( swing, swapping and other deals). Sousuke and Akiba decide to disguise themselves in order to spy a meeting between Shiratori, Shingo and Rika, with Shiratori now on their side;
• While surviving an approach by a horny couple, Sousuke manages to meet Rika while in the bathroom( she doesn't know it's him);
• While spying, we see a side of her not shown until now, openly talking about sex, lust and engagement content( even going as far as saying some women enjoy rape);
• She enters a room with Shingo and Shiratori is left outside. Akiba is caught by some guys and Sousuke miss his chance to bust Rika trying to save her;
• With the plan failing, they decide to recruit the help of Shingo's wife, Mitsuri;
• While approaching her, she threatens to kill Sousuke, and both have an emotional break, because their spouses were cheating with each other. Mitsuri asks Sousuke how can he prove that it wasn't Rika who approached Shingo to start the affair;
• The both settles down and starts a video call with Akiba, Shiratori and Tsutsumi, to orchestrate a plan to catch both cheaters in the family spa trip of the PTA;
• During the trip, the team( and a little help from Shiho) manages to open a breach for sousuke to steal Shingo's pouch, with and SD card inside;
• While checking the SD card contents, Sousuke sees raw videos of sex between Shingo and Rika;
• Breaking down even more and telling this to his friends, Sosusuke see another couple cheating;
• When going to their respective rooms, Shiho asks to play with Tsubasa( Shingo's kid), leaving Sousuke and Rika to take a bath together in the ofuro;
• While there, Rika latches into Sousuke, and asks to have sex, because this would be the last time, before the baby was born. And if he felt doubts, he could ask for a DNA test, because the situation itself was strange.
• While this happens, Sousuke remininsces about their highschool day;
• Sousuke begins to have doubts about this situation and believes that he can just settle for a calm life with her and the 2 kids;
• When coming out of the bath, Momonga channel receives another video, one of sex, where Rika screams in pleasure, saying her AP's d*ck was bigger, and how she wanted/longed to be impregnated by another man;
• When searching for the SD card, Sousuke discovers it was stolen;
• Night falls, and Sousuke almost falls to his death in an accident, but is saved by Akiba;
• They stage a plan to lure Shingo and recover the SD card;
• Shingo tries filming Akiba and Sousuke, in order to compromise them and "have Rika for himself";
• His plan fails, and he is caught by Shiratori and Sousuke;
• During his flashback, we see that he has attention problems, and desires to be seen. He married Mitsuri in order to become an ikemen( handsome guy) and attract more views. However, his views start to fall;
• Rika is the one who approaches him in order to start Momonga and get more views for him. He becomes addicted to the numbers bought by Momonga, thanks to her;
• Sousuke manages to recover the SD card in a...really unique way;
• With the pieces set and Mitsuri keeping Shingo in a leash, Sousuke departs to face Rika, but not before checking the SD card again;
• The videos are all gone, save for an old one of Shingo doing a different girl, while saying made him do it for training;
• When entering the room, Shiho delivers a note of Rika, saying she will be sort some things and return later( with a lipstick kiss);
• The team searches the entire spa, but does not find her;
• 3 weeks pass and Rika has not returned home;
• During a conversation, Shiho asks Sousuke to keep searching for her mother, while calling her grandmother( Sousuke's mother) to help in the House. Shiho also thanks Sousuke for their time together, saying she loves him the most;
• Sousuke decides to get back to his hometown in search of Rika's parent's house;
• While travelling, he meets his childhood friend Misato, and she helps him getting to the address;

- Rika's parent's house has been sold 10 years ago, and now there lies an empty piece of land;

• She reveals that there'll be a class meet, where Rika could be probably going too;
• Sousuke retcons that, from her 18 to 22 years, there's a blank part about Rika's life that he doesnt know about;
• During a series of twists, he ends up staying in Misato and her sister's, Satsuki's trailer;
• Satsuki tells Sousuke that the house was referenced by the people as the "whore house". Neither sister knows why;
• During his stay, at later night, Sousuke is approached by Satsuki, whos asks for sex, instead of money, as compensation to keep him;
• It backfires, as Misato caughts both of them;
• On the next day, Misato and Sousuke go to search for clues regarding the "whore house". On their way, Misato discloses a piece of info that wasn't made public, about Sousuke and Rika's quarrel, but dismisses it altogether;
• During their search, the majority of people in the settlement do not want to talk, and even asks to leave them alone, to forget about Miyase( Rika's family name). Sousuke starts grasping the reality that something really bad happenned, since he's feeling their feelings of discomfort regarding the subject;

- When going back to their motorhome, Misato drugs him, strips him, and starts filmming with him, saying she's "the whore's friend";
- Sousuke manages to stop her from doing the deed and she explains her story;
- During college, Misato had financial problems from her parents/sister, so she went to Rika for help. Rika broke Misato into investment fraud, and Misato started earning a lot of money. During this time, she was approached by Iwabuchi, a man who was representing a victim, and wanted compensation, otherwise he would go to the police. Misato sent a nude and that was it...until it turned out it was a lie, and Iwabuchi used the nude to blackmail Misato into prostitution works;

• Also after this, Misato found out Rika's secret account. Turns out, during her college years, Rika was engaged to Iwabuchi. Misato quickly understood she was set up since the beggining, went to Rika for some explanations and Rika confirmed it. While asking about their relationship, Rika confirmed that she loved Iwabuchi and Iwabuchi loved her. He fullfils her;
• Rika explains that her goal is to feel Ultimate love, because a life without fun is just boring;

• In the present, Sousuke understands even less of her, as Blackmailing Misato and cheating on him with Shingo seems to lead Rika into a path contrary of love, hate;
• Misato also points out she doesn't know if Rika is still close to Iwabuchi, since she married Sousuke. Also, Iwabuchi still asked Misato for some jobs, but this one came specifically from Rika, "to target Sousuke and create a video of adultery";
• They receive a call from Rika;
• While stalling for some time, while receiving threats, Misato manages to "fool" Rika into thinking there was a video, but couldn't send it due to file size. Rika threats her with scattering Misato's nudes and ending her socially;
• Also in the call, Misato asks why'd Rika ask for that, if she was married to Sousuke, wouldn't it be simpler to just divorce? Rika's response was that she needed this video of Sousuke to achieve her goal of true Love;
• Near the end of the call, Misato, a village broadcast starts playing. The calls ends with an ultimatum from Rika, "tonight". Sousuke perceives that the broadcast could also be heard from Rika's side of the all, meaning she was somewhere in the town. The chapter ends with Satsuki not believing how her sister was compromised, and saying she will muder Rika;
• We are here.

So my theory easily broke 😅

She need Sousuke to feel greatest love~
What the value of sousuke ?? The only i could thought the value Sousuke for rika is just the status they are married couple. But rika want misato record when she is having sex with Sousuke. For what ? For threathening Sousuke not divorce her ? But she has the baby excuse. Pregnant wife couldn't be divorce.

So Rika is near them, and also perhaps rika is spying Souske by herself all this time while she is pregnant ? This big possibillity rika herself told shiho to push Sousuke to her hometown when reunion near come, so she could manage misato in right time. Also she wouldn't come to the reunion because she hate so much. But she in there.

As always has cotradictive. we still don't have clear answer. Which is the real Rika, the evil or not ..

I always wanted ending Sousuke defeated rika, trashing her, make rika feeling greatest hate than felling greatest love. But in other side i also they back together as family because 8years is not short and then they are has shiho, so i want all this mess just how rika defend this family.

Haha yes i also, the biggest part of my thought from bginning, that is. But in my naive thought i want they could back together because a lot of time they has been together and even they has been has shiho, but off course i want to see good excuse why rika do all of this awfull things, if this scenario happen.

By the way: chapter 10 and the omake from tankobon 1 were translated.
Reading again helps us remember some interesting points, like:

- Sousuke wants to trail and trap her personally, instead of going to the authorities, as he thinks she may get away from him;

- Senna and Jin talking about how Rika was on her phone all the time, texting her husband. They thought she was on good terms with Sousuke, but Sousuke says she doesn't text him that much when she's on the PTA meetings( as of now, we know Shingo was close to her, so it's interestingly clear there was someone other since that time).

Yap, i've mention about it in some previous comment. After we know iwabuchi has relation in rika before in ch 70 . I think that x person in this series could be iwabuchi

First, God bless your kind heart.

Second… what a dumpster fire. My main issue with stories like this is that the plot often feels overly contrived, and there’s always the risk that the ending won’t be satisfying.

Third, whenever I come across a series like this, I like to check the Shoseki Ranking to see how the physical sales are doing. Here’s the available data:

• Volume 1 – Released on 2024-10-08. The only volume to reach a monthly ranking, selling approximately 6,070 copies in its first month. No data after that.
• Volume 2 – Released on 2025-01-08. Only reached a weekly ranking, with about 3,089 copies sold in the first week. It appeared almost every day in the following week but didn’t make the weekly ranking. Since it showed up consistently, I’m estimating an additional 1,200 copies, for a total of around 4,289 (the second-week cutoff was about 1,350 copies).
• Volume 3 – Released on 2025-04-09. Reached the weekly ranking once, selling approximately 2,332 copies in its first week. No further data.
• Volume 4 – Released on 2025-07-09. Also reached the weekly ranking once, with about 2,372 copies in the first week. No further data.
• Volume 5 – Released on 2025-10-09. Only one weekly ranking, with roughly 1,932 copies sold in its first week. No further data.
• Volume 6 – Released on 2026-01-08. Reached the weekly ranking once, selling around 1,725 copies in its first week. No further data.

Here’s the graph:

As we can see, physical sales are clearly declining. While that’s obviously not a good sign, it doesn’t necessarily mean overall sales are bad.

For example, take a mediocre manga like NTREVENGE. Physical copies account for only about 4.5% of its total sales, and volumes 1 through 7 sold roughly 300,000 copies combined (physical + digital). So this manga may have sold well over 374,000 copies in total.

Edit: @eren760 posted that the author said the manga has reached 200,000 copies sold (physical + digital), and in fact, the author shared this on X on January 8. That means physical copies make up about 9.4% of the total sales.

Man She swallows shingo's cum and I am sure she didn't do that with sousuke.
I think rika's Greatest love is sinho but sinho doesn't give a fuck about her mom and loves sousuke more and that's why rika needs sousuke.

Yap i agree. I also follow ntrevenge. That series really contrived how the mc got power and then can control anyone who has bullies him and then author feels like lossing control about main concept the "Revenge" itself. But i think it bit different for aisai no ura aka. Rather than contrived this series is made too much pressure or suffer to mc. I followed this series nearly never feel happy about sousuke the MC, feels like you read manga sport where the MC always lose and never win. Also after we cornered the guy actor in adultery videos (shingo mori) as the main plot of this story, what sousuke nor us as reader got ?? Nothing, besides the fact mori is bald. and now new story segment we showed more dark truth about Rika past. I think it make sense why hard copy of this series always decreses. Because no one want feel suffer everytime they bought it. Even i don't really want re-read this story again. But i think after all of suffer the MC, how bad conlusion this series will be. I think author option only will make sousuke happy in the end. So i think that enough to satisfy to know sousuke got happy life after all this mess.

Man She swallows shingo's cum and I am sure she didn't do that with sousuke.
I think rika's Greatest love is sinho but sinho doesn't give a fuck about her mom and loves sousuke more and that's why rika needs sousuke.

I mean, a ho3 will be a ho3, but when exactly she swallowed his cum, what chapter 💀☠
And i really liked your theory, i can clearly see the person that she loves the most being her daughter

My only issue with this is that, in Japan, the parent who first leaves the house with the son, gains full guard of the kid, rika didnt

The very first video from Sousuke’s daughter’s school is also further elaborated on in the extra chapters.
That’s where the line “Was it tasty? - Yes, it was very tasty.” comes from as well.

I only have one side, and that side of me wants her ass gone for good, i mean 💀💀

This question has a fundamental constraint - Rika’s pregnancy.
If it is genuine, then, due to his personal “beliefs,” Sousuke will not be able to inflict harm on her (physical or psychological) until this issue is resolved, and he will also clearly protect her from Satsuki’s overly harsh actions.

 

[XiaoNate]

And he would be a fool for that lmao.
Knowing this ho3 real face like we do right now, she may be very well still taking it DEEPLY, DAILY, AND on top of that, RAW.

He cant buy what that b will try to sell us

I only mentioned NTREVENGE as an example because its sales figures were fresh in my mind, not because I’m making any direct comparison about the plots being overly contrived or anything like that. If I wanted a more direct comparison, I would’ve used Rikon Shinai Otoko for the whole cheating-investigation angle, or even Shounen no Abyss for the misery-porn aspect. And both of those titles have a somewhat happy ending that ended up being kinda unsatisfying.

Its a mix between rikon shinai (the difference being our MC dont having to fight for his daughter custody) and a pornhwa i loved to read named guilty circle, with all the mistery behind the characters.

Eh… I don’t know about Guilty Circle. Most of the characters are so cartoonishly evil that it ends up feeling more like a comedy to me than anything else.

I've read full chapter 71.

I want clarify some part for spoiler before.

rika not hated her hometown, but the hometown is hated rika. (Imasara jimoto nante modorenai wa yo - I can't go back to my hometown now ) (Watashi jimoto de kiraware makutteru shi - I'm totally hated in my hometown anyway)
-----

And some interesting part:

About announcement is the lost person is an oldman 87 years old, wearing pink sweater and pink stocking. What the heck with he is wearing ?? 😅 i think author won't doing it without reason.

And also about rika goal doing this to Sousuke.
(Watashi ga hontou no "ai" o kanjiru tame ni, Sousuke-kun ga hitsuyou na no yo - In order for me to feel true "love", I need Sousuke-kun) i've think what if rika doing all this is only want to test Sousuke about his love to rika ?? But this too absurd. Just let it ~

First, God bless your kind heart.

Second… what a dumpster fire. My main issue with stories like this is that the plot often feels overly contrived, and there’s always the risk that the ending won’t be satisfying.

Third, whenever I come across a series like this, I like to check the Shoseki Ranking to see how the physical sales are doing. Here’s the available data:

• Volume 1 – Released on 2024-10-08. The only volume to reach a monthly ranking, selling approximately 6,070 copies in its first month. No data after that.
• Volume 2 – Released on 2025-01-08. Only reached a weekly ranking, with about 3,089 copies sold in the first week. It appeared almost every day in the following week but didn’t make the weekly ranking. Since it showed up consistently, I’m estimating an additional 1,200 copies, for a total of around 4,289 (the second-week cutoff was about 1,350 copies).
• Volume 3 – Released on 2025-04-09. Reached the weekly ranking once, selling approximately 2,332 copies in its first week. No further data.
• Volume 4 – Released on 2025-07-09. Also reached the weekly ranking once, with about 2,372 copies in the first week. No further data.
• Volume 5 – Released on 2025-10-09. Only one weekly ranking, with roughly 1,932 copies sold in its first week. No further data.
• Volume 6 – Released on 2026-01-08. Reached the weekly ranking once, selling around 1,725 copies in its first week. No further data.

Here’s the graph:

As we can see, physical sales are clearly declining. While that’s obviously not a good sign, it doesn’t necessarily mean overall sales are bad.

For example, take a mediocre manga like NTREVENGE. Physical copies account for only about 4.5% of its total sales, and volumes 1 through 7 sold roughly 300,000 copies combined (physical + digital). So this manga may have sold well over 374,000 copies in total.

I see.
I remember reading about this, however, it was in the Shonen Jump. Manga like Nisekoi didn't have that many tankobon sales, but it did have enough sales and spotlight in the main weekly magazine, so the serialization continued for years. In contrast, there was always an issue that Bleach tankobon sales were declining, as well as spotlight in the weekly magazine, that seemed to be the reason for the series starting to become "rushed".

Here,
If both digital sales + physical ones are satisfactory, we'll get a somewhat long serialization and enough time to work on this plot.
Personally, i've been thinkin about 100 chapters to close this story. The plot structure and pacing do give me that feeling.
