I had this idea since this past month and I was interested of writing this. I was inspired by Synépeies's NTR consequences, Ranzolax and others from the Anti-NTR corps subreddit.
Plus some ideas that I came up with. Basically the Idea is 3 SI's got reincarnated into 3 Infamous NTR protagonists and their job was to uplift and redeemed them.
The NTR protagonists are Yusuke from Terasu MC's Kaaya, Min-oo from Ratatatat74's Why are you getting out from there, and Hiroki Mori from Terasu MC's Kokujin no Tenkousei NTR ru.
I chose those 3 as I felt bad for them, so I wanted to redeem them. Let me know if you have any ideas or suggestions, and Critiques, please comment it.
P.S, the original NTR hentais barely had, if not any plot, background, or any setting whatsoever. So I am taking a lot artistic and creative liberties to fill in and build up the overall world. Plus, I am going to add and feature different animes and mangas to make it more interesting and dynamic.
