Always be a little kinder than necessary

Draco Malfoy was friends with a muggle long before they went to Hogwarts. Celestia is that friend. Her parents are one of the people the Malfoy's actually don't mind being with and enjoy their company. Now that both Draco and Celestia are going to Hogwarts, will they still be friends? Will they continue to talk and hang out? Or will they stop talking? Will they stray apart and be separated? Will they become enemies?

I own none of the Harry Potter character's except my oc
The Tomlinson's are real people but Celestia isn't one of them
