You arrived at Hogwarts this year, with yours 11 years. Your house was selected, and while everyone clapped, Barty looked at you from afar.

When Barty saw you there in front of everyone, he just stared at you. He felt a strong sense of protecting you, he was 16 years old and felt like taking care of you for these years.

And from that day on, he started taking care of you from a distance. You had the feeling of being chased, but you didn't know who it was.
