(HP) Reversal of Fate in Another World

Reborn in another world, Severus became the son of a high-ranking noble and a genius magician praised by everyone. And James Potter became the illegitimate son of a declining nobleman, a waste who didn't know any magic or martial arts. Reversal of fate, reversal of life experience, the two meet again... Potter, just wait to die! ! ! PS: I still keep the names of some people in the other world from HP because the author was incompetent in naming them (face covering), but they have nothing to do with HP. The only ones who have memories of past lives are the Professor, JP and SB~
