The first arc of the story is great - 10/10. In my opinion, he author should have ended it right there (kill off the other guy - checked, live happily with his harem - nope, MC threw it all away to "go back in time"). We got slim character development for MC right at the end of this arc but the author cut it short and axed character development for "time travel". MC was going to have to face the consequence of his actions and sorting thing out.
This would be a great turning point from the original work and perfect ending if the MC decided to use his wish to revive his friend and bonding with him in the aftermath (MC got to keep his harem, the other guy got his buddy face off so now they say farewell to each other and went off to other places).
The second arc is 4/10 for me. It could have been a 10/10 easily. Up until this point, the story was not really about NTR. It was about MC doing reasonable thing as a character. If I was in his shoes, I would probably do the same thing. I think this is probably one of the reason some people keep reading this work but not drop it right away even though they do not interest in NTR. It was never about NTR, stealing other people's lover up until this point. It was more like traditional harem story with odd ways of recruiting harem.
The second arc started out pretty good. However, in later chapters, one of the first real NTR element was introduced - the ugly bastards (plural - gangbang happened). The author tried to salvage it at the end and I think he did a pretty good job at salvaging the ending of arc 2 (5/10).
The third arc from the web novel is going to sink like the Titanic (1/10 - some/many Japanese reader of the web novel is probably also agree with this opinion in the web novel comment section). I was pretty excited about a new heroine - the "good" guy's childhood friend that we did not see in the "first loop". We did kind of get what we were promised - MC had sex with her (10/10 for delivering the promise of the story trend - only for this specific part, other parts are still 1/10).
A new ugly bastard was introduced - a real NTR boss. The story was supposed to be about the MC doing the deed (that is why it wasn't feel like a NTR), however, this new NTR boss had his ways with all of the original heroines in the first loop - all of the MC's effort to leave the "good" guy with them went all in to vain. He has his way with the cover character of the first volume. Now, the author just treats his characters like disposable objects. This ugly bastard has the ability to modify other people "status" so he changed their status as his slaves. After he forced MC to have sex with the childhood friend character (first time), he had his way with her after that. For some reason, this ugly bastard had his way with all the other female characters around the "good" guy but not this childhood friend character. He only did it after MC took her first time by his order. The author reason was that he fear the "good" guy might kill/harm him so he didn't touch her. I don't think it makes any sense after he did it now. It would be a good saving point if he kept his stand on not lay a hand on her. Now, the author turned all the female characters into whore/disposable objects. It was about them only doing sex with MC and nobody else - that was a saving grace for me in the first arc - that is why it got 10/10.
I believe that the web novel story went on hitaus for years after this. The manga adaptation is currently at the start of arc 3. I hope that they will change the story for the better.
- limit what that ugly bastard can do, keep his hand off the heroines
- he can have his way with other side characters that we don't know but no sharing partners
- I prefer the female characters only have sex with their person of choice/circumstance
- all the heroines will still fall for the MC - that "good" side character will still get nothing).
If the story really changed in this direction, I will comeback to update this rating to 10/10.
