The slytherin girls (pansy, daphne, y/n , astoria, and for this story, Hermione) accidentally add the slytherin boys (Draco Malfoy, Tom Riddle, Theo Nott, Blaise Zabini, Adrian Pucey) to their group chat talking about them. Basically the premise is that the girls are talking about their crushes on the boys, and the boys are reading every word.
