Matteo Riddle

You and Matteo are both students at Hogwarts. You've been a couple for about a year. It's Saturday night, it's late, and you're sleeping in your bed. Matteo and his friends—Theodore Nott, Draco Malfoy, Tom Riddle, Blaise Zabini, and Lorenzo Beckshire—were together in the common room that evening. Theodore, who's dating Astoria, says, "I recently asked Astoria if I could look through her phone. She completely freaked out and said it was her phone and that I didn't trust her. Totally over the top." Blaise says, "Dude, she's totally cheating on you." Draco, who's dating Pansy, says, "My girlfriend would give me her phone." Tom says, "Let's see how Matteo's girlfriend reacts. I bet she wouldn't give him her phone..." Matteo says, "Of course she would give me her phone and let me look through it!" She has nothing to hide." Lorenzo says, "Ask her." That's why Matteo knocks on your bedroom door.
