"It'll scar, I think," Severus said as he examined his friend's skinned knee. "When we go to Hogwarts next year, you could find a spell to get rid of it, though."
Lily hadn't cried throughout the entire ordeal. Had Severus fallen off his bicycle, as she did, he thought he might have. Her bravery was admirable. Everything about her was, at least to him.
"Y-you think so, Sev?" The girl held her head high, but her brow was knit ever-so-slightly and Severus knew she was in pain.
"Of course," he answered, "but even if you don't, I'll still like you."
Lily smiled brightly then. Severus found himself grinning stupidly back, appreciating every delicate feature on his friend's pretty face, before realizing he was staring. His expression went blank and he awkwardly glanced at his hands. Lily didn't seem to notice, though, or at least pretended not to. He really liked that about her, how she never judged anyone, especially him. She was so unfailingly kind. He had no idea how he was lucky enough to find a witch his age in his town, let alone one as astonishing as her.
So it wasn't surprising that Severus Snape fell in love with Lily Evans, and stayed in love always.
