So I read the whole f*cking novel (which was a pain in the arse) and let me tell you it sucks so much not even NTR fans could defend this shit after getting to know.
First of all there is no actual NTR even after the end. There is BSS when Reiko and Yuuki become a couple and Reiko announces it in front of everybody.
Second, Yuuki almost becomes a yandere which would be interesting but Reiko stops him on time (which sucks tbh because the story becomes VERY formulaic from then on):
Reiko enticing a new person, be it some UB, Perverted shota, lesb0 girl, her own f*cking cousin etc etc. Then do events behind Yuuki's back and make everybody sus/yuuki jealous. Rinse and repeat.
She eventually meets a cult who without getting to know much but the fact that she can obtain cheat "blood" powers (eroge kinda cheats) by ingesting body parts of special beings or some shit...
Then we get to find out she is being prepared to be the vessel for that world's God which is a degenerate. This is why this pos guy was revived as a girl. God tries to take over her body but because of plot armor and the power of her will (st*pid ass explanation but okay)... she manages to make the God disappear.
The end is basically her and Yuuki arguing but everybody supporting them, so they make up. However everybody has hidden intentions to NTR yuuki I guess. Reiko says there is enough time to NTR Yuuki later. The end.
I don't give a flying f*ck about spoilers so don't come crying. Let me do the crying instead.
This piece of trash has been carried by the art and it has been overly hyped by closet cucks around here so I thought it must be something very special.
No it is a disappointment, no actual NTR, the plot is so cliche I can name you many NTR manga and eroge that would be masterpieces compared to this t*rd. The characters are shallow and unidimensional, the plot is absurd with a lot of ridiculous twists everybody saw coming a mile away. Also the MC is boring, after a couple of arcs her exaggerated reactions and explanations are cringy and lame. To top it off that final arc and ending are vomit inducing.
I rather wank with sandpaper than read this slop again lol
