Mattheo Riddle

Matthew Riddle was the typical party boy; there wasn't a Slytherin party he missed. He was also quite the womanizer; everyone in his group of friends was attractive, which is why they brought girls home every day, although they never took it seriously.

Until one day, the girl who set Riddle's life on fire walked in: Rosie Granger. Yes, Hermione Granger's sister. He wasn't that close to Hermione; they had only spoken a few times, and although he sometimes hated her, he couldn't deny that her sister was attractive.

One day in potions class with Slughorn, he gave the instruction to do a group project, and Slughorn put them together. Mattheo didn't pay much attention to it at first, he came to where you were.

— Hey Granger

he said, putting on his silly, popular, coveted-kid smile.
