A/N: This is for Mystii's 30 Drabbles in 30 Days challenge. All of these are going to be Lily/Sirius, but they probably won't be connected in anyway, so don't be expecting a coherent story line. I'm not sure as of right now, but the rating might change later on.

Prompt: "Why in the world would you do that?"

He was waiting in the shadows – waiting for the precise moment that Lily Evans would stroll by on her prefect duties. She walked by every night and never once had she noticed his presence. He never did anything but watch; his feelings were kept as tightly locked away in the shadows as he kept himself in this very moment.

Her footsteps sounding nearby alerted him that she was about to walk by – exactly on time. Her pace was steady, even, and her pale face glowed elegantly in the soft light; her bronze hair swung lightly around her shoulders.

She was the epitome of beauty – and she didn't even know it.

Unconsciously, he let out a sigh as she passed him. Lily froze in her tracks. Sirius instantly held his breath, realizing what he has just done. Slowly, she turns around and starts to look around her. She sees nothing, and Sirius thinks she is about to stop looking when, all of a sudden, her eyes narrow and she heads straight into the shadowed part of the corridor – straight toward where Sirius is hiding.

He tries to shrink further back into the shadows, but the wall is behind him and there is nowhere else to go. She has almost reached him now; he knows he has finally been caught.

"Sirius Black," Lily says as soon as she sees him, her green eyes narrowing.

"Lily Evans," he says in the same disapproving tone, narrowing his eyes at her in return.

"What are you doing up after curfew?" she asks.

"Wouldn't you like to know?" he says with a smirk. He takes a step toward her, his eyes smiling.

She crosses her arms across her chest and looks up at him, waiting. But he doesn't answer; he continues to close the distance between them until they are only inches apart. Lily finally tries to take a step backwards, but Sirius catches her arms, holding her firmly in place.

"You want to know what I'm doing up?" His face leans ever so slightly toward hers. She nods weakly, too stunned to speak. "I was watching you," he admits, eyes smoldering. Their faces are only an inch apart now, and Lily closes her eyes, knowing he is about to kiss her.

But instead of his lips on hers, she feels him releasing her arms, and his footsteps echoing around her. She opens her eyes and stumbles after him.

"Why in the world would you do that?" she calls to his retreating back.

He looks over his shoulder at her and grins. "Wouldn't you like to know?"

A/N: For some reason I was having a lot of trouble with the tense in this, so let me know if you noticed any mistakes. Whether you loved it or hated it, I'd love a review. =]
