She is a saint from a pure-blood family
She entered the academy to study for the sake of her family. It was supposed to be a boring life, but she made many friends in the academy. She would always point the way for others, and she was sure that she was at a loss on her own path. She also met the person she wanted to protect.
He, the leader of Slytherin, the young master of the Malfoy family
With his arrogant and rebellious nature, and the pure-blood mentality instilled in his family, he never made any true friends. Even if he wanted to protect one person in the end, he was unable to.
