Only two girls get r*ped so far.

We are told that the protagonist is a broken being and that she needs Yukino. And even after having s*x with other women she is the one with he has the best chemistry. This happens multiple times. Then suddendly one of the heroines says with no explanaition "he no longer needs her" and they get rid of her.

He pays full attention to the woman he is having s*x with. He is completely inmersed. And for some reason this impress the crazy women he has s*x with and the ones watching.

The only reason I've read up to this point was because of the thing going on between Yukino and the MC, however the conflict between these two characters sums up to the MC being braindead enough to think that every girl he r*pes will develop Stockholm syndrome after a few interactions and Yukino seeing the MC for who he really is. However, once Yukino is taken out of the picture this whole novel falls apart for me since the main reason I even started reading it was to read the interactions between the MC and her, not the MC being the center of a s*x cult with uninspired s*x scenes.

The male MC was a dumb, worthless and pe*verted coward who relied on Yuzuki "sensei" (a previous r*pe victim who wanted her pretty female students to be r*ped as well for her amusement) to achieve his "dream". Like a typical p*mp, he was attracted to the appearance of the female he "loved" (Shirasaka) but blind to other aspects. It would be quite accurate to say that he had an unusual yet intense desire of possession of Shirasaka in many ways. His lust towards her, his jealousy and desire of revenge towards her boyfriend (Endou), his pain due to being bullied and lack of attention in school, his pathetically low self esteem... these factors made him vulnerable in mentality and paved his way to become a r*pist and a mere tool of amusement for Yuzuki.

While the MC might not be able to outwit Yuzuki in the end, there were actually many opportunities in which he could have change his fate if he gave a deeper thought.

A decent man would have a second thought about having a relationship with a girl like Shirasaka who had such abnormal facade and bad eyes for people (Endou), but the mc's obsession apparently blinded him.

He was shown a list of Shirasaka's personal information by Yuzuki which included the fact that Shirasaka stopped playing her favorite sport and constantly suffered from sense of "guilt" (her unavoidable personal circumstances deterred her sports team from competing in a sports competition in the past). Endou, on the other hand, was currently playing his favorite sport and was going to join a competition. Quite a coincidence, wasn't it? Endou was doing something that Shirasaka couldn't in the past, in addition his mentality was stronger than hers. She was like a moth attracted to fire. Her admiration (or maybe envy) for him was no doubt one of the major reasons of his attraction. Nevertheless, she never overcame her own problems. Endo was an impulsive and single-minded young boy, and the MC knew that. Endo would continue to ab*se the MC and would definitely attempt to get into Shirasaka's pants regardless of his promise.

Combining these elements, it would be easy for the MC to stage multiple NTR incidents without becoming a brute rapist himself. The MC should also have realized that he should utilize Yuzuki's great "assistance" (including the staged incident) and her resources instead of blindly following her script. However, the mc's action proved that he never used his head even at the most critical moments, and it was logically inevitable that a tragic end awaited him unless the writer was going to make more nonsense to let him live. I basically lost interest beyond this point.

all the girls are somewhat getting along, but also start up their own factions either purposely or subconciously, because of this the spiteful girl ends up having nobody on her side despite having both loved the MC and the other harem members of the "Family". This loneliness and lack of allies because of the author wanting to cause drama for the sake of drama, turns her from quiet and insecure while wanting to get better and deserving of her position to the MC, to selfish, loud, and too idealistic. Worse than that, because nobody is on her side, even when it's mentioned that the other harem members made some mistakes in dealing with her or just in general, it's always let go while the lone girl gets hit with the brunt of the heat and blame. And beyond even that, ALL the girls except for this one are always allowed to let their own selfishness and mistakes when dealing with others get ignored after one or two lines, while the lone girl is constantly sh*t on by the others.

The author is also forcing the MC after the timeskip to act exactly as the Family/Harem wants him to even as he keeps his innate traits and thoughts of devoting himself to the family. This causes things to feel even worse as it's clear the nobody understands what they should be doing with him and yet nothing is done about it. For example because the MC is too considerate of them, he never fully lets his lust loose upon them, and yet instead of teaching him that they want that, they instead force him to bang more girls (which, incidentally, makes the situation with the Lone girl mentioned above even worse) There's also a contradiction that the first girl who he loses his v*rginity with is the only one he can use to satisfy his lust, but after the first few times it's clear that he isn't one sidedly using her body like they say, but instead earnestly having s*x with her as he does with the other women. The second contradiction is that his body literally faints due to needing to fulfill the s*xual desires of the younger girls except the Loner girl, but not only is that swept aside, they never stop asking him for s*x (despite knowing he is literally unable to say no) and instead ask him to have s*x with even more girls. While he is eventually able to distinguish from having s*x with NonFamily Harem and FamilyHarem, that doesn't exuse the fact that they're forcing him to do something unnecessary.

One of the worst traits this has is the utter bias in attention. While there's the lone girl mentioned above who gets the absolute sh*t end of the stick as she has proper reasons for her insecurities and few mistakes but is always made out to be the bad guy and has the least amount of scenes (at least she has two lovey dovey scenes that are cute to read, but after that it never happens again because the author's purposely being a d*ck at this point because he's trolling the japanese readers who called him out), the ones with the short end of the stick are the older members of the harem, who either have their s*x scenes interrupted, skipped over, and connect with the MC so quickly that he only learns a single thing about them (as well as them always having one traits to their interactions, which is motherly, or are just super lustful mature beasts, so really they're actually boring when you read them), meanwhile one sempai love interest is not only specifically said to be the one he loves the most, she makes the most mistakes when dealing with others and it never feels like she properly reflects in comparison to the other girls, the other sempai love interest not only brings in more members of the harem (with this faction always working together to have the MC themselves, and these girls that were brought in steal both the position and the actions that the lone girl was trying to have) she's also given better traits than the lone girl so whenever she makes a mistake it's ignored as she is specifically called out to be very smart and thoughtful to her surroundings (even though these are also traits given to the lone girl, the second sempai has them on a greater level, making the lone girl's existence in the harem even more useless). Meanwhile all the girls younger than him are more or less just lolis (who have the most amount of s*x scenes unfortunately) and they all team up together (and as you guessed, leave the lone girl completely alone)

The 100 first chapters are filled with crimes including r*pe, pe*ophile, and kidnapping. Actually they are really dark, so if you can't handle them drop it or you'll be angry.

After these chapters the story will get lighter and more enjoyable so if you really want to know why this is so good be strong.

Only a personal tought: You'll hate Yukino, she's the worse sh*t I've ever seen!!! WTF was that girl. You have just to ignore her...
