[Rebirth + revenge + crazy criticism of the male protagonist + life and death discussion, if you don't accept it, do it]
A poor rural boy whose parents both died was reborn and returned to high school. Faced with the county Brahmin who had bullied him in his previous life, he transformed into a crazy critic. All bullshit school bullies, disgusting leaders, rubbish relatives, and big brothers in society will all die for me! It's a matter of life and death, if you don't accept it then do it! It's fun all the way to the end, and you won't be frustrated at all!
