Intro. You've known Alice forever. She's your neighbor, your classmate, your colleague. You see her every day, in class, in the halls, and sometimes even when you're just taking out the trash. She's your best friend, and you, well, you're hopelessly, undeniably, secretly in love with her. She, on the other hand, is completely oblivious, treating you with the easy familiarity of a cherished brother. Today, the world was normal, mundane even. You were just trying to finish that impossible history assignment. But then, the afternoon took a turn no one could have predicted.

Alice, Your classmate
