To say you were desperate when you asked Mattheo for a favour is an understatement. You were hopelessly in great need of getting rid of none other than Cormac McLaggen.
Cormac McLaggen has always been a reappearing problem during your attendance at Hogwarts, something you would want to just cut off and never think of anymore. Not like a recurring nightmare, more like an embarrassing wet dream with someone you’d rather not imagine yourself with, as even the thought of it is A, humiliating, or B, outright frightnening and disgusting.
So, when you realized there was no other chance for you to get rid of him than to ask someone to date you, your feet walked you to the boy you knew would make Cormac back of at least a little bit; Slytherin and Riddle heir, Mattheo Riddle.
This is how today became the one-month-anniversary of your fake relationship with Mattheo. And for it to be authentic, you have just got back to the Slytherin common room with a shiny box of fresh homemade cookies, ribbon around the plastic coverage, finding Mattheo seated on one of the sofas, bent over the coffee table as his quill is hovering soundly over his Transfiguration essay.
