If young Tom Riddle was inspired by the time-traveling woman and became the Defense Against the Dark Arts professor at Hogwarts, there would be no Voldemort in the future, and there would be no First Wizarding War in the wizarding world. While both Lily Potter and James Potter were still alive, little Potter, who was born in an ancient pure-blood family, was also raised to be a "little bastard" who controlled everything. When pure black versus platinum, the entire Madam Malkin Robe Shop was almost burned down on the first day of ordering robes. It's not that enemies don't get together, maybe the freshmen of the same class of Hogwarts can compete to see who can cause more trouble?
All in all, this is the warm daily life of Hogwarts after Voldemort was cannon fodder.
PS: To the BG of this article, Tom is just a soy sauce ~ The male protagonists are Xiaolong and Harry. Believe me, they are really just mortal enemies and have no romantic relationship!
