I don’t know why, I feel that the golden age of NTR has disappeared recently. I haven’t seen any works that I think are excellent, whether it’s literature, animation or games. So I had an impulse to write an article, but I didn’t write it for a long time, and I felt a lot rusty. Moreover, it was very difficult to write a real article. It was not easy to stimulate and have a strong sense of substitution. But now that I have written it, I’d like to share it with you.
