In retrospect this is waste of time. Nothing great really except the art. From chapter 1 to chapter 37 its your typical Harem story despite making huge mistakes of how NOT to do it (Will talk about it later). From 37 to 49 (the very last chapter of this series) it feels like the genre got changed, story didnt made even less sense and it feels/reads as it was axed or rushed. So in short, 3/4 of the story is fine if you like harem, the rest is trash which got axed at the end.
Story: While it got potential it was wasted by the authors poor writing skills about his characters or how the whole curse worked. Not only we saw a sudden shift in the genre, but also a unfixable character change of the FMC Rikka. What was a just horny FMC towards MC, turned into a nymphomaniac cum-dump slut in your classic NTR doujinshi where she only thinks about Dicks, since this is what she prefers now.
While the author somehow tried to backpaddle, he realised he made a Oopsie with her arc, but also his whole manga. He tried to excuse her action with only "there was no penetration so she is still pure" but for some reason he ignored Rikkas love to fuck strangers just because.
The is a funny scene where even a main love inteterest points out why Rikka would do such even she is supposed the be THE main girl, ranking above all the others, where the other girls didnt even thouhgt about the idee to cheat on the MC. It was kinda a way of the author to say he made a mistake but didnt know how to fix it.
As time goes on, he realised people left for good and he needs to wrap things up. Which means he needs to rush things and end where they are.
And with that got our time-reset ending where nothing really made sense. The very last chapter ends with MC simping for the FMC slut, chatching her once again where she wanted to go out for another gangbang part, got persuaded to have sex with MC and he dies. Time gets reseted, we start from Chapter one while its hinted that the other love interests somehow have deep feelings for MC...
The problems:
The story made a simple mistake to make MC and Rikka a couple, which is kinda hard to make in a Harem story where you have multiple woman. While mostly it can be done nicely, here I will agree that MC was cheating on her because thats how bad the story is written. It started as your typical cliche of MC to save the other girls but also starting to have his own romantic feelings for them, which is nothing new for a Harem story.
What made it bad is that the FMC not only got ignored for he majority of the time, but since her character got changed, it made her unacceptable for the majority. While her action make sense in a seinen or drama story, here in a Harem manga it was out of place.
The other problem is the NTR, which was the main reason the manga got axed.
While I would say NTR dosent automaticly will tank your series, its about how you execute it.
There was a manga im forgot the name but its about how MC got NTRd by his wife and he moves on on his harem path with the FMC being the sister of MC now Ex-wife. The scene of MC being cucked is so short and there wasnt even much shown, pointing out that its only for the plot and not fetish.
"Kanojo ga Senpai ni NTR-reta node, Senpai no Kanojo wo NTR-masu " is another good example how you even have sex scenes with the girlfriend cheating on MC but we dont feel bad about it since she is not even the FMC but she is not likeable. Also here its for the plot and not for the fetish.
Well, in Lust Geass we have the opposite. Not only reads both of the NTR chapters as your typical NTR doujinshi, which is only for the fetish, there is no follow up or a slightest amount of redemption from the story.
While it could have been fixed with not much effort, it shows how bad the author is in writting his stories. This or he found a new fetish which dont mix well with how the manga started years ago.
Conclusion: I liked the manga before the NTR happend, but since it happend anyway I thought it would at least have the balls to end on a "mature" type of path. I dont mind to have a shit story having a shit ending hence I expected not much of it. But the time reset was a cheap cope out to find a common ground with his fan base it seems. What he also didnt get is that Rikka continues to be a nymphomaniac slut, even in this time line tho we wont see it... because thats her true character, which the author never fixed in the first place since this was established as her true herself, her true desire etc.
Personally I would have prefered that MC would have dumbed the FMC from the first chapter she cheated on MC and focused on the other girls. And after some years the meet randomly and become friend but without romantic feelings since MC realised he never truly really loved FMC but was horny, otherwise he wouldnt have cheated on her. And FMC is also happy since she is a nymphomaniac slut, she is also married with a new guy but also cheats on him since this is her true self.
But all we got was a simping MC for the hoe FMC and the story really forces her on the MC.
In the end, if you are a Harem fan dont read it, at least not from the MC side.
