A/N: This is an AU story and I have never done one like this for Castle before, also this will be my first multi chapter story for this amazing couple. This will be my version of what if Castle and Beckett didn't know each other. Now I am sure this is nowhere near what will happen and I said please keep in mind this is AU. I would really love to hear feedback on this.

"The first time I laid my eyes on you I knew, we spend this life side by side. I still feel the same though you're so far away. I swear that you will always be my forever love, I will be waiting for you forever love."

-Forever Love

The sun came blazing in from the window, the second window in his office. The damn window he always forgets to shut the blinds on. The same window that Beckett complains about him always leaving open and waking her up on her one and only day off. Yeah that is the window that was disturbing him on this particular morning. Castle groaned in protest, he didn't want to wake up and leave the warm confines of his bed, but he knew if he didn't shut the window his fiancé was not going to be a happy camper and cranky Beckett was not good for none of them, especially him (if you know what I mean).

Castle rolled to his right side still half asleep. He reached out for his love only to find her side of the bed empty. That was strange. Why would she be wake on her only day off? She had told him very firmly he better not wake her up in the morning for no reason at all on her first day off in over two months. Castle yawned, not giving her reason for being awake at this hour much more thought and climbed out of bed. He made his way through the office and into the kitchen where he expected his find his wife to be having her morning coffee. But he didn't. The lights were off, the room was dark, and he could sense something was wrong. He just didn't know what. He flipped the light switch by the counter on.

"Ahh." He screeched. "What the hell?" He asked out loud to no one in particular.

He was in his loft that was for sure, but what the hell had happened here last night. Everything was wrong! There was an ugly ass couch where his favorite one used to be, and it was on the wrong side of the room, the décor in the place was not his, and he knew for a fact this sure as hell was not Beckett's taste. All of his pictures he had of Beckett and him from the Hamptons were gone. But why? Who? He thought.

In the middle of his self ramblings he heard footsteps coming down the stairs.

"Hey dad."

"Oh Alexis, thank God." Castle said as he turned to his daughter. "Alexis, oh my God, what did you to your hair?" He asked his now black haired daughter.

Alexis scrunched her noses up at her father, "First off dad I have told you don't call me Alexis anymore."

"But.."

"Dad I told you its Lexie now, and secondly, my hair happened six months ago I don't know why it's so hard for you to figure this out. Come on dad get with it." She said as she rolled her eyes at her dad.

"I wish I could." Castle said taking in the strange information.

"Lexie, where is Beckett?"

"Who?"

"Katherine, Kate, Beckett. My fiancé."

Alexis laughed. "Good one dad."

Castle now scrunched his nose up at his daughter. Alexis grabbed the paper off the counter and tossed it to her father. "My guess is Beckett is at the office whoever you think she is to you dad she is not." Lexie said. 'CAPTAIN KATHERINE BECKETT"

"Something's never change; she is still dedicated to her job. Thank god for something familiar." Castle said to himself after reading the headline out of the paper.

Castle grabbed his jacket from by the door, and headed out to see if Beckett could tell him what the hell was going on today. He took the same route to the precinct; thankfully it was still the right way to go. In fifteen minuets he was climbing from the car and taking the elevator to the place he knew all to well.

When the ding of the elevator indicated he had reached his destination, he grew anxious to see her.

"Beckett, Beckett." He called over and over again.

"Ryan, Espo, thank god where is she? Where is Beckett I have to talk to her now!"

"Captain." Ryan called.

Castle turned to see Beckett walking out of what use to be Gates' office.

"Yes?"

"This man says he needs to see you. You know him Captain?" Espo asked.

"I have never seen this man before in my life." Kate said.

Castle heart stopped, the blood drained from his face, and with those few his words everything he ever knew was gone.
