My ambotious concept is something deep and philosophical. Well, there are two favorite kinds of stuff which is sexual and relatable.
About relatable:
Well, to many people even readers alike are kinda complicated to my concept, but basically, what I'm working on is the story about the NEET protagonist had reincarnated to another world (kinda cliche); however, I won't make it as Isekai just for the sake of isekai, but something happened within him, and his goal is nothing except there might be crucial part which drives him to approach his goal in later plot... which means that the first half of the story is like slice of life with tension part. Straightforwardly saying about this concept of mine, it's just the boy who had the ability to stay alive even when you got hit by anything vital inside your body. He is also being discrimanated by most society since he is represented as a big threat, when in reality, he isn't, though. Well, the title of the story is Trap and Fade.

About sexual:
Well, this is my perverted side, so who cares about being a disgusting being of me. But I don't want some cliche vanilla shit like most hentai shows and mangas usually do regarding the plot. It's like, I want to make it humorous and hardcore about hentai—in other words, action comedy. The concept goes like this: The main protagonist is a female AV actress from the time of cyberpunk... well, the rest is up to me when I will start writing it. I want to write in Natsume Akatsuki's style (creator of Konosuba) since he has the ability to add humor and interaction (dumb humor) other than... for the sake of comedy. Also don't forget about relationship and three-dimensional personalities. This will become my future idea for now, but I want to focus on my second work. I had the first work called Optabilis Mundo which is kinda a bit shitty to write tbh., but I do miss these characters, so rewriting will do the trick.
