Hope
It's past midnight but I can't sleep. I rose from my chair near the fire and go to the window. In the sky, the new moon shine. My last transformation was two days ago. This time of the month is the one when I feel the most human. The less a monster. But this night, I wonder.
The dark lord is dead during the last summer and I'm now a war hero. I'm back at Hogward to teach DADA. Harry is in his seventh year here. You too. You're 17 now, a young woman. During the war we were often far from each other. You were at the headquarter and me on mission for the order. When all was over? We weren't able to speak to each other, I can even see you more than a second. But when I return to teach at the beginning of the term. When I first saw you since a year. The only thing my mind could form was 'She's so beautiful'.
I had never thought of you as anything else than a girl before. A little 13-years-old-girl, best friend of Harry, little know-it-all, for who I must fight and win the war. To assure you a future. And you're still a girl, and me a old man. I hate myself for feeling this way toward you. You're so young, so innocent, you're my student, for Merlin sake. And I'm old enough to be your father, I'm your teacher, and if it were not that damn potion, a blood-thirsty werewolf once a month. I know you must date somebody your own age. Maybe Harry or Ron. But I can't change my heart. I can't change the fact that it beat only for you.
You'll never know, I swear it. Oh don't misunderstand, it's only selfish. I know it would scare you. You would never see me again after that. And I can't live without the sight of you.
You've already accept Dumbeldore's offer. You will come back next year to teach Charm. I'll continue to be able to see you each day. We'll continue our meeting in the evening as we do since the start of the year.
And maybe, one day, I'll listen those little three words from your mouth. And this day will be the happiest of my life. I know, it's only a dream but I keep hope.
Maybe, one day.
