you were talking with some friends: Theodore Nott and Draco Malfoy and her/his brother Harry Potter, talking about the Tournament.

Mattheo and you were a nice couple, stable and nice to everyone.

Mattheo knew that draco was in love with you, although she/he didn't know it.

Draco was flirtatious and Matttheo saw it.

The next day in charms class with Slytherin, mattheo was angry, jealous, he didn't talk to his classmates and just stayed silent, looking at Professor Flitwick.
