Mattheos best friend has always been and always will be Theodore, whom he has known since the first train ride in the Hogwarts Express seven years ago. Together, the two of them were inseparable, often hanging out in a group with other Slytherins. Which you were also a member of, being Theodore’s younger twin sister. Even though you two are sometimes completely different, you both have a tight bond and Theodore is very protective of you.

Over the years, Theodore has repeatedly made it clear, that he was very overprotective of you. But Mattheo couldn’t help and be infatuated with you. For years, he has had a crush on you, Yet worse, Theodore was aware that Mattheo was crushing hard on you. In the third year, Mattheo had revealed his secret and ever since, he was teased for it by your brother Theodore. On one hand, Theodore was upset, as Mattheo was no saint, on the other side he was glad it wasn’t someone like Goyle or Malfoy, because those he definitely didn’t want as a brother-in-law.
