DNF Meets Harry Potter

Cough, three days later, the author will enter the first final exam of the Evil High School. As we all know, the assignments of teachers in various subjects are directly proportional to their grades.

I hope to pass the exam a little better for a good year, and the salted fish will be changed for a few days.
