HP: Qingmei Doesn't Believe Me, Why Did You Come Over Here?

(Not a cool story, the main plot, don't read if you don't like it!) There are twists and turns in the early relationship, and there will be explanations in the middle and late stages. Don't read if you only like cool stories. If you come in, you don't have the patience, so why come in! Slytherin from the Muggle world, Gryffindor, who is also a childhood sweetheart from the Muggle world, and there is also a Potter beside her. Looking at the three people below, Snape fell into deep thought, are you going to kill me? This is a magical world, and the protagonist is a soul from the 21st century. How can he not know the greatness of science? Then, what kind of sparks can the combination of magic and science splash out? This is a story about a protagonist who is a little bit second-year, and is pushed to the position of the Dark Lord step by step by his good friend! The most important point is that Hermione fits the original character, and her character is not likable. If you like the kind of vase Hermione, please don't come in! ! !
