Raising a Pet at Hogwarts

Chris, who was reborn in England at the end of the 20th century, just wanted to grow up safely and become a world rich man in the future relying on the power of the Internet. However, he received a letter from a magic school. "You said the school is called Hogwarts? Are you kidding?" In this way, Chris took his pet dog and joined the Hogwarts family for a limited period of 7 years. I thought I would spend my 7 years of study in peace, but in the end... McGee, you gave me too much of a surprise. What does it mean that you are invincible in fighting magical animals in the Forbidden Forest, and you make friends with a basilisk! ! You and Sirius are considered brothers. What are these? ? ? ?
