This is only my second Fan fiction. I'm not entirely happy with it but I've gone over it so many times it was giving me a migraine! I hope you enjoy it.

I don't own Castle, unfortunately.

"So…You get your invitation?"

She sucked her breath in through her teeth, slammed her pen down on the desk and closed her eyes.

"What Castle?" She answered once she'd opened her eyes and controlled her breathing. She was trying to wade through the mountain of paperwork that had been on her desk for four days and the last thing she needed was an audience. Castle was generally fun to have around, especially at a crime scene, but she was sure he had better things to do than play angry birds whilst she worked.

"Ryan's wedding. You…have been invited haven't you? Please tell me you have or I'm going to feel like a total tool." The worried look on his face made her smile inwardly.

"Yes I have my invitation Castle. Why'd you ask?"

"No reason, I was just making small talk" He went back to his phone.

"Don't you have a book to write? The Lockhart case must have given you some kind of inspiration this week? Or was it not freaky enough for ya?"

"I'm actually way ahead of schedule so I have some free time." He wasn't really getting the hint.

"Castle! If you want to stay here then I need you to be quiet. I would like to get this paperwork done. I do have a life you know." She really hoped he wasn't going to ask her to elaborate on that. The truth was, this was her life, she spent more time at the precinct than she did at home and when she was at home she was either in the bath or in bed. She hadn't even plugged her TV in since she'd moved in after her apartment blew up. She had Josh but with both their schedules so unpredictable the only time she saw him these days was for sex. How romantic. She couldn't even remember the last time they had been on an actual date, or been out to a movie. She sighed. It was becoming clearer and clearer with every day that things with Josh just weren't working. It wasn't fair to keep him hanging on when her heart clearly wasn't in it.

"Beckett? You ok?" Castle's voice broke her reverie.

"What? Yeah, I'm fine."

" So….Josh coming with you?" He wasn't sure if he wanted the answer.

"Erm…No, he's got to work. How about you? You managed to charm some poor unsuspecting female into accompanying you?" She added the last part on quickly to avoid any 'Dr Motor cycle boy' quips.

"Detective you wound me with your words." He replied with mock indignation.

"Couldn't find anyone then?" She smiled.

"Nope" He pouted.

"Wanna go together?" The words were out her mouth before she even had time to think about it. She could feel the blush rising up her neck and settling like plum tomatoes on her cheeks. She didn't need to look up, she could almost hear him grinning.

"Like a date?" Were all the words he could muster.

"As in share a cab" She backtracked. "It makes sense." Her heart was ready to pound right out of her chest and land in his lap. She looked up at him and literally saw him deflate.

"We can't have the famous Richard Castle turn up at a wedding ALONE." She tried to lighten the mood, it seemed to work.

"I'll pick you up at 5 Detective." He grinned.

She was about to protest and suggest that she could just meet him outside his building but he was up out of his chair and nearly at the elevator. By the end of the night she'll never want to let me go he thought as the doors slid shut.

Kate had been standing in front of her closet for what felt like hours. She was still in a towel, her hair practically dry and the ticking of the clock loudly reminding her that she had less than an hour before HE was coming to pick her up. HE being Castle. Rick Castle. It shouldn't be a big deal. They were two friends going to another friend's wedding. Together. Then why were a kaleidoscope of butterflies threatening to burst from the very pit of her stomach? If she had been going alone, as she had planned, she would have been ready hours ago. She let the towel fall to the floor and she couldn't fail to notice the scar near her heart. She had grown very fond of her scar. It was a constant reminder of how close she came, of how precious life is and how Castle had saved her life. Castle. Everything came back to Castle. He had been 'different' since the shooting, distant almost. She understood. Her job was dangerous. His shouldn't be. He had a family that were counting on him and by following her he was putting that in jeopardy. The last year had read like one of his novels and she was beginning to see what everyone else was seeing. He cared about her, maybe too much sometimes but he was there. Always. Josh had told her that Him and Castle had had what he described as an altercation at the hospital when she was in surgery. He hadn't offered any more information and she hadn't asked for anymore. When Josh asked her if she had feelings for Castle, she said no, her heart screamed YES. Josh was safe. He couldn't hurt her because she felt nothing for him. It was that realisation that caused her to break up with him just last night. She could feel tears threatening behind her eyelids. She reached her hand into the closet and grabbed her favourite black dress. She'd had it for years but she loved it. It was simple with a sweetheart neckline and reached just below her knee. It hugged her figure like a silk glove and accentuated every single curve. For some reason her eyes were drawn to a pair of India green heels at the back of her closet. As she grabbed them she heard the door. Her heart rate increased significantly, she took a last look in the mirror and tiptoed to the door. The first thing she saw when she opened the door was the biggest bunch of crimson red roses that she had ever seen.

"Castle?" The flowers moved so she could see his face. His mouth fell open.

"Wow. Beckett you look…" his eyes travelled up her body and landed at her lips.

"Hot!" It wasn't the adjective he wanted to use. He wanted so badly to tell how she was the most beautiful sight he had ever seen, how she literally took his breath away every time she looked at him. How he thinks about her ALL the time. How he misses her so much that it physically hurts. But, she wasn't his. He had no right to say these things to somebody else's girlfriend. She stood to the side and let him in, he went straight to the kitchen to find a vase for the flowers. She stood there. Hot she thought. She hated that word. It was what Josh called her when he'd turn up late at night after a shift with only one thing on his mind.

"I just need to grab my purse and I'm good to go" She shouted as she disappeared into her bedroom. As she slipped her shoes on She took one last look in the mirror. Here we go she thought.

It wasn't until they had gotten out of the cab that Kate had realised that Castle's tie was the very same green as her shoes, a fact that Castle had seemed to notice at the same time.

"Great minds" He smiled as he offered her his arm, which she took.

The others were there when they arrived. Esposito was nervously standing at the front next to Ryan, who looked remarkably calm for a man about to marry. They headed towards Lanie in a pew off to the side and sat down. Castle greeted Lanie with a kiss on the cheek. This bothered Kate. It shouldn't. Lanie was more than happy with Esposito and there was never anything said to suggest that Castle was interested in her. But why hadn't he kissed her when he picked her up. She shook her head and settled into her seat. Lanie leaned over to say something but the music from the organs started and they were invited to stand. Jenny looked beautiful. Her smile radiated around the church as her happiness infected the whole congregation. Castle looked round and caught Kate's eye. His heart ached. He smiled. The smile he received back failed to reach her eyes. He loved her. It was as simple as that. Every bone in his body loved her. He didn't take his eyes off of her through the whole ceremony. If she noticed she never mentioned it and she never told him to stop.

The reception was being held in a hotel not too far from the church. By the time Kate got there it was in full swing. She had taken a detour through the park on her own so she could think. Things were no clearer but she had decided that she needed to speak to Castle. Maybe it was time to tell him that she had feelings for him. She walked straight over to the bar and ordered a martini. She looked through the crowd of people trying to find him. It didn't take long. She just had to look for the 6ft blonde model in the corner. She couldn't hear what he was saying but he was all over her. It was embarrassing. She downed her drink and ordered another. She felt sick.

Castle was trying to find Beckett. He'd intended on waiting by the bar for her but he'd spotted Alexis' violin teacher on the other side of the dance floor and gone over to say hi. As he scanned the throng of people by the bar he spotted those legs. Those long, smooth, beautiful legs. He made his way over to her and sat on the stool next to her.

"Hey, I've been looking for you"

"I bet you have." She couldn't hide the venom in her voice.

"What's wrong Kate?" He was confused. At the church she had seemed sad. Now she just seemed angry.

She got up off of her seat and grabbed her drink.

"I'm just fine RICK." He reached for her arm and got up. They were facing each other.

"Hey guys" They both spun round.

"Tom?" "Demming?" They both exclaimed at the same time.

Thank you to everyone who has taken the time to read. The reviews I received for my last FF put me on cloud nine and has inspired me beyond belief. I do have ideas on where this is going to go. It will probably be 2 or 3 chapters in total.
