[Hp]this School Has a Big Problem

One day I came to a magic school called Hogwarts. I found that there were not only the savior, the blond young master and the bat professor, but also the cook who was good at chemistry and became the Potions class representative, the tailor apprentice who kept the yarn ball as a pet, the senior sister who was too timid to leave the dormitory, and the thief lady who stole the Hand of Glory and raised a sniffer... In short, this school has a big problem! Ps: It's a lot of short stories that have nothing to do with the "I" of the copywriter. Intention: Big problem!
