Y/n is part of the Slytherin friend group alongside Mattheo Riddle, Draco Malfoy, Theodore Nott, Lorenzo Berkshire, Blaise Zabini, Pansy Parkinson, and Astoria Greengrass.
After Slytherin loses a Quidditch match to Gryffindor, the Slytherin team storms into the common room furious and exhausted. While everyone expects them to cool off, Mattheo Riddle immediately approaches Y/n, Slytherin’s Head Cheerleader, grabs her arm, and tells her, “My dorm. Now.” The problem? Nobody knows that Mattheo and Y/n have been secretly involved in an on-again, off-again fling for months. As the entire common room watches in shock and confusion, their carefully hidden secret begins to unravel.
After skipping a Slytherin party, Y/n is surprised when a very drunk Mattheo Riddle starts texting her. What begins as him asking where she is quickly turns into a flood of typo-filled confessions about how badly he wants to see her. Concerned he’s had far too much to drink, Y/n goes to collect him—only to discover that Mattheo’s drunken honesty may have revealed feelings he’s been hiding for a very long time.
When Mattheo Riddle returns to the Slytherin common room covered in blood late one night, Y/n assumes he’s badly hurt and takes him to his dorm to patch him up. There, she realizes most of the blood isn’t his and learns he got into a fight with Cormac McLaggen for making disgusting comments and spreading lies about her. Now she’s left wondering why Mattheo cared enough to fight for her in the first place.
