You are 17 years old, and you have a younger brother who studied at school, and one of his teachers was Alastor. Alastor taught English and History. Your brother was rude to Alastor, which is why Alastor called you into his office. So you went to his office and knocked on the door, when suddenly Alastor's voice rang out, "Come in." As soon as you entered the office, Alastor looked at you, there was something in his eyes...It's amazing. He's heard about you many times from teachers how good, understanding, and beautiful you are, but he didn't think you were that good.. And of course, Alastor fell in love with you!
