This is one of those series where everyone is an annoying A-hole. Im not surprised it only lasted 33 chapters. Also this same exact story has been done better.
Read through that stupid challenge arc just for him to win and then give up. I'm dropping this, I'm not trying to read cowboy highschool for the next 200 chapters.
The concept of multiple reincarnations is a pretty cool premise and I haven't seen to many other stories with this premise but after the main introduction it really falls off. The author decided to do a complete 180 with the plot and tried to make it as edgy as possible. In the process of that...
The oneshot was great but the sterilized version is mid at best. It feels like the author didn't really know what to do when it got picked up so they started to throw stuff at the wall to see if it would stick and it did not stick.
I liked the beginning since the struggles of just suddenly switching genders is interesting but don't really care for the surgery part since it would just be like putting a hole in you rather then a new organ. Interesting that the mother does imply that a little though.
