His pale hand slid along the cool, grey stone wall, which made up the side of the Hogwarts castle. He had promised himself years ago that he would leave her alone, but she haunted him, every time he closed his eyes and saw her angelic face, so deeply engrained in his mind, his heart would shatter every time he recalled it.
He stopped, peering over the edge of the wall, drinking in the sight of her, and trying desperately to ignore the man sitting beside her. Age had not changed her. For as long as he could remember, Lily Evans had been beautiful. Her head was thrown back toward the golden heavens, laughing freely at what the black haired man had said, and then nudging him playfully. They looked at each other, the other boy and she, and as little as Snape wanted to admit it, he could feel the time stop by merely watching them.
It was not until she leaned forward and pressed her lips to his that Snape could feel tears running down his face. She intertwined her long delicate fingers in his hair, pulling herself toward him until their lips met again. And as the sun set further over the lake, casting the two lovers in a golden hue, an endless night settled over the heart of Severus Snape. He allowed himself one more glance before tuning his back and walking away.
The dementor slid forth, engulfing Snape in desolation. Clutching at his aching heart, he couln't stop the memories. The last time he saw her. At the lake. Lily Evans, laying in the arms of James Potter: His angel, in the arms of his enemy.
And from the darkness of the night, a silvery doe sprang forth.
