Can someone make a story of castle having a new detective in the 12th and then they become close friends. And she is teaching Castle a self-defense thing. And then Kate being miserable in DC decide to return to 12th. Castle and Kate didn't talk after the rejection of proposal. The knew detective look like Olivia Dunham..bec. I like her in fringe and she's beautiful and intelligent. I hope someone can make a story because im not good in storytelling just only pop in my mind reading others writers story.

Heavy breathing… but it feels good. Castle thought.

Seeing his new partner coming to him. "Hey, I'm surprised I beat you this time" he said.

"Well must be your luck. I'm so drunk last night that's why I'm not in a good shape this morning". Olivia said rolling her eyes at him.

They were in a park in New York. Its their routine now every morning to have a run. And now Castle can see his hard work. He lose his weight, return his body like the first time he started working in the 12th precinct. His built body more masculine because of their training, Olivia offered him to teach him a hand-to hand combat for self-defense so when they were on the field he will not be liability.

"Luck! No, it means im getting better than you." He smirk.

"Really! Let's see later who is better huh! I am going to kick your ass on our training later" She said.

"Well see about that. Anyway you want to grab a breakfast?"

"Remy's?" "Yeah." "So what are you waiting for? Let's go so I was the one who will kick your ass." He laughed. She slap his arm laughing. They are always like this bantering each other. Castle thought he could never have this friendship again towards to other women but he was wrong. Olivia Dunham, the new beautiful, amazing, bad-ass detective who replace Kate Beckett. While they were walking to Remy's he thought for the last 5 months.

His head is hurting, and so his heart. He never thought that Kate's rejection to his proposal will lead to him drinking every night. His mind destructed by ringing of his phone. It's the 12th Precinct. Thinking twice if he will answer. But decided to answer it.

"Castle."

"Yo, bro. its Esposito. I wanted to check if your up to a case. We have a fresh one. And we are looking for your crazy theories."

When he will about to stand his head hurt. "Damn".

"You okay Castle?" Espo asked.

"Yeah, just give me the address."

"Castle?" "Yeah" "We miss you bro". "I miss you too guys." And then he hang up.

12th Precinct.

Castle doesn't know why he felt nervous it's like his never been in the precinct before. When the elevator open, some curious eyes look at him. He doesn't know if its pity or surprise that he return to twelfth given that Beckett no longer working here. When he is about to go to Ryan and Esposito's direction he did not see the woman who is holding a cup of coffee walking behind him. But when he stop he accidentally or she accidentally pour her coffee into his back.

"Ouch!". He yelp.

"Oh! God I'm sorry". "What the he-" he doesn't finish his words. When he see the woman who standing in front of him. He cannot describe if she was an angel fall from the sky. And he was mesmerized. Someone slap his back to come out of his daydreaming.

"Yo, Bro are you okay?" Yeah". "I guess".

"Good to see you bro" Ryan said. Hugging him its been 2 weeks since they last saw him.

"I'm sorry I didn't see you. Are you sure your okay?" Olivia asked concerned.

"Yeah, its nothing I can change later" castle said.

"I'm Detective Olivia Dunham, from 9th just transfer last week."

"Rick.. Richard Castle." I know. Your quite popular here." She blurted out.

"Ow" its only he can say.

Capt. Gates see who's outside of her office that her detectives stop from what they are doing. "Mr. Castle, how are you?", "I'm good Sir." " It's a surprise to see you here, not that I don't want you here but, since Beckett is no longer here, I'm thinking that you will not come back here." Capt. Gates explain.

"Esposito call me they said they have a case and I decided to help them out."

"I see, but as you can see we have a new lead detective it's up to her if she wants you on her team."

"I don't mind." Olivia interject.

"Are you sure?" "Sure" "But Mr. Castle is you responsibility." Gates tell her with a look telling that she is in charge of him.

"I know. And I will explain to him my rules if he's still willing to be my partner." Smirking.

Castle shock how affected he is by this new detective. Hearing her talking its like a music in his ear. He shake his head. What the hell is he thinking. He just meet this detective and he is already fascinated of her.

Maybe this time he sees Kate on her. Remembering her brings backs the ache he is feeling in his heart. And he decided today that he will start living his life the way he wants. That is working in twelfth, helping solve murder giving closure to the family, giving justice to them. That's one thing that Beckett never take away from him his fascination. But the happy, nine year-old on a sugar rush will come out, because the love of his life walk out on him choose working DC over him.

"So? You wanna know what my rules are?" Dunham asked.

"Huh?" "Yeah" waking up from his thought. He never realize that is the start of a good friendship between him and the new detective.

After 5 months she becomes his best friend, partner, drunk buddy. And He becomes to her as a break up buddy. He was there for her when she was in a heartbreak due to her boyfriend for 2 years cheated on her. And then decided that they will be each other companion in and out of work…
