The concept is not new but it is different enough. Instead of being in a time loop or given a second chance, this one pushes the line of being reincarnated as the person you most despised. He has the chance to change the world. Could have done with less cussing but it seems like this too was purposeful as his language does shift a little over time. He also seems excessively ornery but as the story progresses he starts smiling and even laughing more and more.
Not bad. I'm not much for the male into a female body trope but this one didn't make it feel weird nor was the MC a perv. I live the violence and character of the MC tho the story kinda drags and is sometime hard to get thru. I hope it gets more interesting as the story goes on as this one had a lot of world building to do. Still love most of the character.
