Disclaimer: I don't own Harry Potter, it's rights, or it's characters. That's all JKR. I'm just a fan writing a story. No money is made off of this, and no copyright infringement intended!

I got the title of this story from the song "Collide" by Howie Day, which was a partial inspiration for the story.

Summary: She was the one girl who could resist his charm. She was the one that made it worth his while.

A/N: OK, so after seeing all these other Sirius/OC stories, I had to do my own. I know this has probably been done hundreds of time, but I wanted to do my own take. This is basically my first Marauder Era story. You won't see Peter much in this because, well honestly, I just don't like him. :) I hope you like it!

Chapter 1 – Who's That Girl?

"This year's going to be awesome," James exclaimed happily as they were eating breakfast.

"How so?" Peter asked curiously.

James smiled. "Because Wormtail…We're seventh years. It's our last year at Hogwarts. And since I'm Head Boy, with all that time we have to work together, I think this year might be the year Evans finally says yes to that date," he said, glancing dreamily at the redhead a little ways down the table when he mentioned the last part.

Sirius chuckled. "Keep dreaming Prongs," he drawled teasingly.

James rolled his eyes as he turned to his best mate. "Yeah? I don't see you with anyone yet. We've been back for over a week and you haven't even asked a girl out yet," he retorted.

Sirius rolled his eyes, about to retort when Remus teased, "That's because he's already dated almost every girl in our year, not to mention quite a few that aren't in our year."

James laughed at that, while Peter chuckled, and Sirius scowled at Remus.

"If you must know Moony," Sirius started slowly. "I've actually just been weighing my options."

"You're options?" Remus repeated skeptically, eyeing his friend closely. "So, what options are you weighing exactly Padfoot?" he asked, in a tone that suggested he was patiently talking to a young misguided child.

James smirked as he watched Sirius contemplate his answer. Peter was looking back and forth between them as if it was a tennis match.

"I was actually thinking about asking her out," Sirius replied smoothly, nodding down the table.

The others glanced down to where Sirius had nodded and noticed Lily and a couple of the other seventh year Gryffindor girls.

"Well, you're obviously not talking about Evans," James stated. "Or at least you better not be," he added, with a slight threat hanging in the air.

Sirius chuckled. "Don't worry Prongs, I'm not after your bird."

James grinned. "Good."

"Didn't you date Erica last year?" Peter asked, motioning to the blonde talking to Lily.

Sirius rolled his eyes. "Fifth year Wormy," he corrected.

Peter nodded. "Oh right."

Remus, though, was looking at the other girl, then turned back to Sirius. "Which one are you talking about?" he asked carefully.

Sirius smiled. "Her," he answered simply, motioning to the girl with dark brown hair, sitting across from Lily and the blonde, that Remus had been looking at.

Remus's eyes widened slightly as he looked at Sirius incredulously. "Hailey?" he questioned in surprise.

"That's her name?" Sirius asked, furrowing his eyebrows slightly.

"You don't even know her name," James chuckled.

Sirius rolled his eyes, but Remus shook his head.

"Her name is Hailey Anderson," Remus told his friend. "But I think you should probably try asking someone else."

James and Sirius both looked at Remus curiously. "Do you like her Moony?" Sirius asked. "Because, if so, then I'll happily back off and let you go for it," he added sincerely.

Remus rolled his eyes. "No, I don't like her. Not like that anyway. She's just a friend," he informed them.

"Then why should I ask someone else instead?" Sirius pushed, back to his bright self.

"Because she's not someone who's going to be easily impressed by you like most of the girls in this school," Remus answered simply. Sirius cocked his head sideways and looked at his friend questioningly. "Hailey's not going to fall for that famous Black charm of yours."

Sirius smirked. "I believe that's a challenge mate," he commented.

James chuckled, and Remus just rolled his eyes.

– X –

"Think you could put in a good word for me Moony?" Sirius asked his friend as they made their way to Charms.

Remus rolled his eyes. "No."

James and Peter looked at each other and smirked, barely containing their chuckles. Sirius had been trying to pry information on Hailey out of Remus since breakfast, but so far Remus had answered everything with 'No'.

"Oh come on Moony," Sirius pouted. "Why not?"

"Because I value my life Padfoot," Remus retorted as they took their seats in the classroom.

"Just give it up Padfoot, Moony's not gonna help you out on this one," James told his friend, trying, unsuccessfully, to keep the amusement out of his voice. "Trust me. I've been trying to get his help with Lily for years."

Sirius rolled his eyes, but then noticed said girls walking into the classroom and smirked. "Well, maybe luck's just on my side today," he shrugged and got up and started walking over to their table.

Remus and James caught each other's eye and shook their heads.

"Hello ladies," Sirius greeted brightly as he pulled up a chair.

"Did Potter send you over here?" Lily asked in annoyance.

"No," Sirius answered honestly, but with a look of mock offense.

Lily looked taken aback for a second. "Oh. So…Why are you here?" she questioned suspiciously.

Sirius smirked and looked at Hailey, who was reading a Muggle book. Lily noticed and looked uncomfortable.

"Um, I forgot, I need to go ask Professor Flitwick a question about our essay," she muttered, then got up and walked off.

Sirius watched her, and then turned back to Hailey. But before he could open his mouth, she said, "So, now we're alone. What do you want?"

Sirius raised his eyebrows, she hadn't even looked up from her book. "I just wanted to talk," he told her lightly.

She raised her head and half-glared at him with her light brown eyes showing her impatience. "Bull," she stated simply.

He smirked. "OK, fair enough," he agreed, raising his hands slightly in a peaceful gesture. "I was actually wondering if you wanted to do something with me this weekend."

Hailey raised an eyebrow. "Yeah? Like what?" she replied, feigning interest.

Sirius shrugged, smirking slightly as he leaned in so their heads were closer together, and answered smoothly, "Whatever you want."

She smirked as she too leaned in a little closer and replied in a slightly curt tone, "I think I'll pass." And she sat back up and went back to her book.

"Why not?" Sirius pressed, though not as brightly as he'd started.

He noticed her roll her eyes as she sat her book down and looked him in the eyes.

"What is this? Now that you've finally gotten through practically every girl in this school, now you decide you're gonna ask me out? Well guess what…I'm not interested," she told him bluntly. Sirius raised his eyebrows at her, but had to grin at her feistiness. "Now, get lost."

"Or what?" he teased. Hailey scowled at him, and he smirked. "Come on, say yes and I'll go back over to my table," he said politely.

"No," she stated lightly. "Now go back to your table," she added firmly, with an air of authority about her tone.

"Come on Anderson, say yes," he pushed.

She rolled her eyes, and glared at him. "No."

"You know you want to," Sirius said pointedly, with a grin.

Hailey took a deep breath. "Don't ask again, and go back to your table," she told him calmly.

"Ju-"

"Silencio!" she muttered, pointing her wand at him before he even had the time to register what she was doing.

Sirius tried to say something, but without success. Hailey smirked victoriously, and waved at him.

"Buh-bye now," she said cheerfully, waving him back to his table.

Sirius gave her a grin of praise, but took the hint and went back to join his friends, who were laughing quietly at this.

Sirius sent Remus a pleading look.

Remus smirked and said smugly, "I told you so." But then took out his wand and undid the silencing charm.

"Thank you," Sirius muttered after regaining the ability to speak.

James couldn't stop chuckling though. "Looks like there is someone out there who can resist your charm Padfoot," he teased.

Sirius rolled his eyes, but glanced back over to the girls' table, where he saw Lily and Hailey talking.

Remus shook his head slightly at his friend and told him, "I tried to warn you."

Sirius looked at him and smirked. "Oh, I haven't given up yet," he stated.

Remus sighed tiredly, shaking his head.

A/N: Well, I hope you enjoyed the first chapter! I already have the second chapter written, but I'm not going to post it until tomorrow. I figured I should spread out posting them a little. But as long as I don't get busy or distracted by other stories, I should be able to post new chapters fairly quickly. Reviews are greatly appreciated!
