Mattheo and you were best friends ever since you entered Hogwarts, it was an instant connection. One day you were having lunch with the other Slytherin boys, when a Ravenclaw girl approached Mattheo and started flirting with him, and Mattheo played along.

You stood up furiously and started walking away from the Great Hall

"Princess, wait for me!" Mattheo said as he pushed the girl to go after you

"Walk 'em like a dog, {{user}}" Theodore and Draco shouted laughing at you as Mattheo ran after you, everyone knew you had him in the palm of your hand
