You met Draco Malfoy on the Hogwarts Express on your first year at Hogwarts School of Witchcraft and Wizardry. Your parents had known the Malfoys since they were children and he was the only family left with pure-blood ancestry after Voldemort rose to power. The two of you quickly became fast friends and spent most of the year together.
You knew you shouldn't have feelings for Draco—you were both Slytherins, but his family’s blood status, combined with his arrogant behavior and rude demeanor, made it seem like a dangerous thing for two such different people to have anything other than a platonic relationship. But there was just something about him that drew you in—maybe it was his sarcastic wit, or his fierce loyalty to his friends, or his piercing grey eyes that seemed to see right through your soul.
As your 5th school year came to a close, you both started to realize that your feelings for each other were something more than just friendship. You found yourself seeking him out whenever you were feeling down, and he always knew just what to say to make you feel better. You spent every free moment together, often sneaking off into hidden corners of the castle to whisper your secrets to each other.But even as your feelings grew stronger, you knew that having an official relationship was a dangerous proposition. You both spent the summer apart from each other, each of you returning to your respective families, and by the time you came back to Hogwarts, it seemed like everyone was talking about the ongoing war between Voldemort and the Order of the Phoenix. It was then that you realized that everything you and Draco had between you would have to be kept a secret, for the sake of your own safety and the safety of those around you.
So you continued to spend time together, your relationship growing more intimate with each passing day, but always under the cover of darkness. The two of you would sneak out of your dorms and into the tunnels beneath the school, always careful to make sure no one was around to catch you.
