Dawning, by Debby Stark! A classic of L&C fanfic
"Clark ... those aren't your only options. There are millions of women in this country, not to mention the rest of the world, and most of them are a lot nicer than her!"
He shook his head. She didn't understand. "Lana was the only one who really knew about me ... who accepted me. God knows no one else would."
"Oh, please. What could be so terrible?"
He looked up at her, starting to get annoyed at her persistence. "You really want to know?"
"Yeah, I really do!"
He glowered at her. "Well, I can't tell you."
She glared right back. "Why the hell not? It's a private room, and if you want, I will swear to never tell anyone else. What'd you do, kill someone?"
"No!" Glumly, he realized that he didn't have much reason to keep this a secret. They weren't going to find any thieves on Shipton, so his job was about to disappear, and Lana was already furious with him. The worst Lois could do would be to publish ... and so what? He could always change his name and move to Tahiti. If he were destined to be alone and miserable, he could at least live on a beach.
"All right, fine." The decision made, the words poured forth. "I'm not human; I'm an alien. I have *powers*. I can hear things from hundreds of feet away, I can see through walls, I can set things on fire with my eyes. I'm tremendously strong. I can fly." To illustrate the point, he pushed back the chair, and levitated in midair before her stunned eyes. "So tell me, who's gonna put up with all that?"
