Everyone knows Y/N Slytherin as cold, calculating, and impossible to read. The kind of person who always seems three steps ahead and never lets anyone get close enough to see what they’re really thinking. What nobody knows is that they have a weakness for greenhouses, quiet afternoons among the plants, and the stubborn little seedlings they secretly nurture back to health. When Professor Sprout pairs them with Cedric Diggory for a mandrake repotting assignment, neither expects much beyond a few hours of work. Instead, they find themselves drawn to stolen conversations between rows of plants, dirt-smudged smiles, and a connection that grows faster than either of them intended. There’s just one problem: a Hufflepuff golden boy and a Slytherin with a reputation to protect aren’t exactly a pairing Hogwarts would leave alone. So they’ll keep it secret. If only falling in love were as easy to hide as a potted plant.
