Coming up with unique NTR stories is not that difficult because honestly everyone uses the same cliches to the point where everything else seem fresh in comparison. Like, I remember the doujin where the girl cheats on the guy, then breaks up with him after she admits that she cheated on him. Twist? The guy is sad, but takes it rather well and walks off with some pride left (imagine not becoming a cuck in an NTR doujin) and when the girl tries to get together with the bull he replies with basic "I was never serious about this relationship", which completely breaks the girl. I dont remember the ending specifically, since its been a long time, but the girl either sexually assaults the bull of her ex-boyfriend in the park, boyfriend sees him and there is no sadness or regret in his eyes, only pure disgust. You see, this sounds generic as hell, but on NTR market is a godsend because almost nobody does it.
As for the art, this game looks good but I am always skeptical with NTR art. Because, despite what people say about "NTR art being superior" unless it is 1-2 page combo on some guy's patreon most of the time it is as generic as vanilla or sometimes worse. Like shit you not, there is a doujin artist who draws the same bloody doujin again and again: same character designs, same poses, same story, sometimes it even seems that it is the same panel layout. I just hope that the dev will not fall under the same slope, but so far their game looks good. I am not a fan, but my honest opinion this looks better than majority of RPGM NTRs that all look the same.
