A/N: I know I have two other stories going already, but I wanted to get this idea out and see how it would be received because it's been in my mind for awhile. I like Harry/Bellatrix pairings, but there aren't a lot of them out there. Maybe for good reason. Idk we shall see (obvs this isn't connected to my other stories, where Bellatrix is with Voldemort). This is just the little prologue, so the chapters to follow would obviously tell the story of how this came to be :) do you like it?

Prologue:

March 1997

Harry was trying to pay attention in Defense Against the Dark Arts class, but it was no use. He was thinking about her. Or rather when he could sneak off to see her again.

Snape swooped around the room going on about nonverbal knockback jinxes, but Harry couldn't listen. He knew Snape was an accomplished Legilimens, so he couldn't think about her too much or he'd give their secret away...but whenever he tried to think about another girl...Ginny, Cho, Parvati...even Hermione and Tonks...literally any girl whose face he could implant over hers whenever Snape stared too intently in his direction...it was no use. The woman of his daydreams had curly black hair, russet brown eyes and lips he couldn't stay away from...

He was already spending nights with her whenever he could get on "watch duty"-easy, since Ron had Quidditch practice and Hermione had homework for her additional classes. Sometimes he could sneak off and see her on a free period if Ron was with Lavender and Hermione was in the library, but he feared they were starting to get suspicious.

He'd tried to cut himself off...but just like with the Half-Blood Prince's Potions textbook, he couldn't get enough of her.

The bell rang signaling the end of class and Harry was ready.

"I reckon we should probably use our break to get started on Snape's homework-McGonagall's bound to give us loads," Hermione said briskly. Ron had already been snatched up by Lavender Brown and Harry knew Hermione was purposely trying to look away from them and almost felt bad about leaving her, until he remembered who was waiting for him upstairs.

"Look, Hermione, why don't I meet you in the library? I've left my Transfiguration stuff upstairs in the dormitory and I want to get it now so I don't have to run off right before class." He hoped she wouldn't suggest she'd go up with him.

"I'd say I'd go up with you, but I think I just saw some...rather unsavory company...head up that way, so do you mind if I go on ahead to the library?"

"Fine, perfect," Harry called a little too quickly over his shoulder as he sped off to the seventh floor.

He didn't know how he'd gotten in so deep with someone so evil, and he knew that at some point soon they were going to get caught and their world was going to come crashing down...but maybe it was for the best.

Still, he'd never felt this way about anyone before. Not even Cho Chang. It scared him, of course, but he'd also never felt more excited.
