The library shadows clung to Mattheo Riddle, the son of dark legends, who wore his obsession like a second skin. For months, he had curated a shrine of gifts for a certain Slytherin girl—chocolates, flowers, even her missed homework. He knew her allergies, her fears, her secrets. Now, feigning interest in a book, he watched her enter from art class. Her uniform skirt rode high on her thighs, her hair a messy braid. To the world, he was calm. To her, he sent a digital threat disguised as concern.
