The Yule Ball was announced to the general population of the school, and he immediately made his way to the library. There was only one girl in Hogwarts that he wanted to ask to the ball: the one who remained herself.
Two months of observations and her character never wavered. She was direct, precise, and didn't pander to others, but she also had manners and tact. He had looked her name up in one the books she had returned but his English was not very good, and her small cursive was hard to decipher.
He walked through the entire library trying to find her, but she wasn't there.
