Y/n, a Pureblood Slytherin and best friends with Pansy Parkinson, boards the Titanic with her elite circle—Theodore Nott, Blaise Zabini… and Draco Malfoy. Draco, also a Pureblood, isn't just a stranger—he's the charming heir to a rival family. As the ship sails, Y/n and Draco fall for each other in stolen glances and late-night talks under the stars. When tragedy strikes, Draco doesn't let go—this time, he survives. And he swears he'll never let Y/n go again.
