Some days are unforgettable. Not because you expect them to be… But because they change everything. You’re Emilia Y/L/N, a Slytherin with an ordinary life at Hogwarts. Your best friend is Hermione Granger. Your boyfriend is Draco Malfoy. Your uncle happens to be Professor Snape. Life isn’t perfect, but it’s yours. Until one ordinary Potions lesson, an owl arrives carrying a letter from home. One letter. One classroom. One moment that changes your world forever. Because sometimes the hardest battles aren’t fought with magic… They’re fought with heartbreak.
