Chapter 1: Unexpected Returns

J.K. Rowling owns Harry Potter, not me.

AN: So this is my new story. I'm really excited to start this since I love Sirius Black. Here's a small summary: Sirius Black and the rest of the marauders are starting their final year at Hogwarts. The war is raging around them, but they are safe at their school. Sirius is trying to get over his ex-girlfriend, Olivia Parker, who left the country a year ago without a word, when she returns to Hogwarts. Where did she go, and why didn't she tell him? Can he forgive her for what she did, or is it too little, too late?

SPOV

"It's true," I said to Peter as the two of us sat in out compartment without the other half of the marauders. Remus and James were both in the prefect carriage. Remus was a prefect, while James was the head boy this year, so Peter and I were left by ourselves.

"I don't believe you," he said, staring at me with his beady little eyes. "There's no way that's true!"

"There's no way what's true?" James asked, walking into our compartment with Lily Evans, their hands clasped.

"It is true!" he shouted, falling off his seat. James chuckled before he and Lily took a seat. Remus came in behind them.

"Calm down, Wormtail," James sighed. "It's not a big deal."

"Not a big deal? This is a moment in history—James Potter and Lily Evans are going out," I said, grinning at him. He punched me in the shoulder.

"Shut up, Padfoot." He pretended to be pissed off, but he grinned back at me. He had been happy as a clam since the end of the summer when Lily Evans agreed to go out with him. She had finally said yes after two years of saying no.

Remus pulled out a book while the rest of us started talking.

"Can you believe we're 7th years now?" Lily asked, looking excited.

"Well, we have to decide what we're going to do once we leave Hogwarts," I reminded her.

"All I want to do is fight You-Know-Who," James said gallantly.

"You'd make a great Auror, baby," Lily said.

"Aww, don't you two make the perfect couple," I said, pretending to gag.

"Speaking of the perfect couple," Remus said, looking up from his book, "Have you heard from Olivia?" Everyone turned to look at me.

"Why would I have heard from her?" I asked angrily.

"She is your girlfriend," he said.

"Was," I corrected. "She was my girlfriend. Girlfriends don't just leave the country without telling their boyfriends."

"Have you heard from her?" he asked again.

"No. I haven't spoken to her since the day before 6th year started."

***

"Okay, open your eyes!" I said. Olivia opened her eyes and saw the box sitting in front of her.

"What's this?" she asked, looking confused.

"Happy six-month anniversary!" I said happily.

She looked crushed. "I didn't get you anything!"

"It's okay," I said, putting a lock of her hair behind her ear. "I wanted you to have this anyways."

She lifted the lid off the small box and peered inside. She reached in and pulled out a silver chain with a heart charm on it. In the heart, there was a sparkling sapphire that shined when the light hit it.

"It's beautiful!" she gasped. "I love it! Here, put it on me," she said, handing me the necklace. I stood behind her and clasped the chain around her smooth neck. Once I finished, I spun her chair around so she was facing me. Then, I lifted her up and sat her in the kitchen table.

"I really like the necklace," she whispered in my ear, sliding her hands around my waist.

I pressed my lips to hers and was about to pull back when she reached around my neck and pulled me on top of her.

She ran her fingers through my hair as she kissed me. Her skin was so soft and smooth. I inhaled her scent as we were kissing—roses and strawberries. She picked her leg off the table and wrapped it around my waist. She stuck her tongue in my mouth, and I quickly returned the favor.

We lied on the table, making out. I moved my hand from her back to her knee and started inching up her bare leg. Since it was summer, she was only wearing a skirt and a tank top. I slid my hand under her skirt as her body shivered. Things were just starting to heat up when we heard someone cough.

We broke apart and looked in the corner. There stood James, my best friend, grinning at us.

"I see you gave her the present," he said, stifling his laughter. I grabbed the box Olivia's necklace had been in and chucked it at James before I rolled off her and got off the table. Olivia fixed her shirt and smoothed her hair as she stood next to me.

"Don't let Mom and Dad catch you doing that, or they won't be as keen to let you stay here," he warned. He turned to walk away, changed his mind, and turned back to me. "On second thought, don't let me catch you doing that where we eat. Disgusting!" Laughing, he walked down the hall of Potter Mansion before heading upstairs to his room.

I turned back to Olivia. Instead of standing next to me, she was staring out the window in deep thought.

"What's wrong?" I asked, coming up behind her.

"Why are you so good to me, Sirius?" she asked.

"What do you mean?"

"Why are you such a good boyfriend? What did I do to deserve someone like you?" She turned to look at me and I saw there were tears in her eyes.

"Sweetie, what's the matter?" I asked. Olivia was the strongest person I knew—she never cried.

"I'm just so grateful I have you," she said, wiping away her tears. "I mean, no one has ever given me something like this before," she said, pointing to the necklace.

"It's not a normal necklace," I said.

"It's not?" she asked.

"No. That stone will only be blue as long as I love you."

"What?" she asked, her eyes widening.

"I love you." It was the first time I had ever said it to anyone and truly meant it. Olivia was the best thing about my life and I wanted her to know it. I expected her to be thrilled. I didn't expect her to burst into more tears.

"Oh, Sirius, I'm so sorry!" she sobbed before running out of the house.

"Did I do something wrong?"

***

"She never told me she was leaving," I sighed once I finished my story. "I loved her, and she didn't even have the courtesy to send me a letter telling me where she went." I slumped in my seat and scowled.

"Tough break, mate," James said, his arm around Lily. "Well, on a good note, I saw Taya Clarke checking you out at King's Cross."

Lily nodded. "She told me she fancies you, Sirius. You should ask her out."

"Why would I ask her out?" I asked.

Remus, Peter, and James all sighed. "Padfoot, you haven't gone out with anyone since Olivia left. As a matter of fact, you haven't talked to a single girl besides Lily and Leighton since she left,"

"That's not true!" I said, even though I knew it was. Lily and Leighton were Olivia's best friends, so I clung to them like a dementor clung to a miserable soul, hoping Olivia had contacted them and I could badger them for news about her. They hadn't heard from her.

"Maybe she had to move," Peter suggested. "I mean, lots of people are moving in this time. Maybe she had to go into hiding."

"Why wouldn't she have told me?" I asked.

"Because you wouldn't have let her go," James said, looking at me. James, my best friend, knew me so well. Sometimes, I swore he knew me better than I knew me.

He was right. I wouldn't have let her leave. I love her too much.

No, not love. Loved. As in the past. As in not anymore. I didn't love her anymore. How could I love her when she left me without even saying goodbye?

After she left my house, she didn't write me back to tell me what was the matter. She wasn't at King's Cross the next day.

When we got to Hogwarts, Dumbledore said she had decided to study abroad. What kind of girlfriend leaves the country without telling her boyfriend?

When I checked out her house over the winter holidays, it was deserted. Her entire family had just picked up and left. Maybe they had decided to go with her.

Why didn't she tell me where she was going? Why didn't she tell me what was wrong? Why didn't she tell me she loved me?

"You all should get changed," Ellie White said, sticking her head in our compartment. "We'll be there shortly." She left, followed by Aiden Wood, her steady boyfriend.

I sighed and pulled my robes out of my trunk. I pulled them on, and then sat back down, thinking about Olivia again.

***

"Please?"

"No."

"Pretty please?"

"No."

"Pretty please with a cherry on top?"

"No! Black, why won't you just get it through your thick skull that I'm not interested?"

"Because I'm irresistible," I said, flexing my muscles at her.

She glared at me. "You know, you think you're God's gift to women, but I know what you really are."

"Oh yeah? What's that?"

"A stuck up, arrogant, jerk who won't take no for an answer!" She huffed and threw her books in her bag, storming out of the library.

"What was that all about?" James asked, taking a seat where Olivia had just been sitting.

"She turned me down again," I sighed.

"So ask her again."

"No. I give up."

James looked at me.

"What?"

"Padfoot, she's you with boobs. I've never met anyone else who loves to prank as much as you."

"You're right. We're perfect for each other." James was right—Olivia Parker was exactly like me. She came from a family of Purebloods. She hated Slytherins, especially Severus "Snivellus" Snape. She loved pulling pranks. The one difference was that her parents weren't into the whole Pureblood mania like my family. Also, she never got into trouble. She could weasel her way out of any kind of punishment.

"Just ask her again," James suggested.

"Prongs, it isn't that easy. There's something different about her. It's like she's immune to my charms."

"Really?" he asked, his eyes getting that familiar gleam in his eyes. "I like a challenge…"

"Don't even think about it," I said, throwing my potions book at him. "She's mine, so hands off."

"Fine," James grumbled.

"Besides, we all know you pine for Lily Evans, the Muggleborn princess of Gryffindor."

James threw my potions book back at me. I was about to say something to him when the door to the library opened and Olivia stormed back in. She marched over to my table and looked at me.

"Can I help you?" I asked, giving her my best I-know-I'm hot look.

"Okay, you win. You can take me to Hogsmeade, but no touching, no hand-holding, and no kissing!" She glared at me before leaving the library again.

"Congratulations," James laughed. I threw the potions book at him again.

***

"Padfoot, move your ass," James called to me as the Hogwarts Express emptied. I looked around and saw I was the last one left in our compartment. I quickly got up and followed everyone out of the train.

Remus, Peter, and I got a carriage while James and Lily got one. I saw two girls join them—one with straight blonde hair and one with deep brown curly hair that reminded me instantly of Olivia.

Get her out of your head, I told myself. She's been gone for a year. If she hasn't contacted you by now, she never will.

The carriages headed up to the school. Moony, Wormtail, and I were sharing a carriage with a Hufflepuff named Peter Bell. He was in our year, but I thought he was a bit dim.

We finally made it to the castle. Moony, Wormtail, and I met up with Prongs and Lily, and the five of us headed into the Great Hall. When Lily met my eyes, she smiled at James, like they were sharing some kind of secret.

"Okay, what's going on?" I asked them.

"Nothing," James lied. He always was a horrible liar.

"James, tell me the truth."

"You'll find out soon enough," he said before taking a seat at the table with Lily. Puzzled, I sat down next to him, trying to get him to tell me whatever the big secret was, but he wouldn't say a word.

"Padfoot, would you shut it?" he finally said, annoyed.

I pretended to be hurt as we waited for the sorting to begin. Professor McGonagall led the new first years in as I looked them over.

The sorting began. I cheered for every new Gryffindor. When the first Slytherin was called, I glanced over at their table and spotted my younger brother, Regulus, sitting with our cousin, Narcissa Black. They both spotted me and shot a glare in my direction.

I sighed and turned back to my friends. James was already talking about our first prank of the year. James lived for pranks, and being Head Boy obviously hadn't cured him of that.

Once all the kids had been sorted, Professor Dumbledore stood up.

"I can tell you are all hungry, so I will only say a few words: Dig in!" The plates in front of us filled with food and I grabbed one of everything and started shoving it in my mouth.

Lily looked at me disgustedly.

"What?" I asked with my mouth full.

"Nothing," she said, daintily nibbling on a sandwich. I shrugged my shoulders and resumed devouring my dinner.

Once I was full, I relaxed. I still couldn't believe Olivia had been gone a full year.

"Cheer up, Padfoot," James said, throwing a roll at me. "There are plenty of girls to pick from. You just need to move on and reclaim your title as Hogwarts playboy before Snivellus takes the title from you.

My eyes narrowed into slits. "You honestly think old Snivelly could take my title away? What girl would even talk to him, let alone date him?"

Lily cleared her throat and I looked at her. I saw she was glaring at me.

"Oh, sorry Lils. I forgot you two used to be friends. I mean, what other girl would talk to him?"

She shook her head as I scoped the Gryffindor table for eligible girls. I saw Taya Clarke wink at me and I flashed her my biggest grin. I saw her blush and turn back to her friends. I could already tell this was going to be a good year.

Once all the plates were cleared, Dumbledore stood up again and cleared his throat. "I know you all want to get to your dormitories, but I have a few start of term announcements. First, I'd like to introduce our new Defense Against the Dark Arts teacher, Professor Hannah Ackerson."

The Great Hall broke into applause while I leaned next to me and whispered in James' ear. "I'm betting five months."

He turned and grinned at me. "You're on! The usual?"

I nodded. "The usual."

Every year, James and I had a bet on how long the new Defense Against the Dark Arts professor would last. The loser would have to run into the Great Hall during breakfast and dance on the table. It was always the highlight of the year.

Dumbledore cleared his throat and continued. "Those wishing to try out for their house Quidditch team should submit their names to their heads of houses."

I zoned out as Dumbledore gave the other notices. Blah, blah, blah. I'd heard it all before. I looked over at Taya and winked at her. Her cheeks turned bright red as she tried to hide her smile. I grinned and leaned back against the table.

"And finally, I have an exciting announcement to make." I looked up and saw someone standing next to Dumbledore. I would have recognized her anywhere.

The long brown curly hair that went right above her boobs.

The soft, creamy skin that felt like feathers.

The wide brown eyes that were always lined with black liner.

The small pouty lips that you wanted to kiss.

The tiny body that was perfect in every way possible.

The mischievous expression on her face that meant she was planning something.

Olivia was back.

Olivia, who had haunted my thoughts and memories for a year, was back.

I heard murmuring in the Great Hall as everyone realized she was back. Dumbledore cleared his throat and everyone shut their mouths.

"After spending a year studying abroad, we are very pleased to welcome Olivia Parker back. She has decided to return to Hogwarts to finish her 7th year." He gave her a warm smile as she took a seat at the Gryffindor table. The Great Hall applauded lightly, but I just stared at her.

There went my best year ever. My ex-girlfriend was back at Hogwarts.

I was screwed.

So there's the first chapter. I hope you like it! Please review and tell me what I can do better or what/who you'd like to see!
