Something's Wrong with My Hogwarts

[Rebirth of Voldemort vs. Harry Potter from the future] Tom Riddle: I was reborn. I was reborn in 1942 when I was in fifth grade. In my previous life, I was Lord Voldemort, the feared Dark Lord in the wizarding world. However, I was defeated by him because I believed in Horcruxes and underestimated Harry Potter. After being reborn this time, I decided to learn my lesson and take back everything that belongs to me and make everyone pay the price... Wait, why did Harry Potter arrive in 1942? Why is he the Defense Against the Dark Arts professor? No, no, no, no, that's not what "Harry Potter" is about! [Warning: Riddle will be suppressed in the early stage]
