When I opened my eyes, I found that I had really arrived in the world of Harry Potter and became the savior of the school. The work has nothing to do with Harry Potter himself. After all, the heroine is the snake house, and the CP is Cedric, embarking on a love journey of a little snake chasing a little badger. The ending will be B, and of course I will also write a side story where everything goes well, so please feel free to eat it.
Intention: time travel
