A best friend is someone who is there for you no matter, every argument, every fight, everything and anything they are there. Sometimes you fall past friendship and love them more, it's always your best friend and sometimes it's only one of you, which is how it is for Castiel. To love your best friend in ways he couldn't possibly imagine while being a closet gay was hard, so he locked it far away and kept it hidden but this love and this secret was growing bigger and bigger, it was only a matter of time before it was unlocked.

Dean glanced over to his best friend of 7 years and only person in the world apart from his brother he could fully trust. He watched as he stared hard at the screen and typed his work up for tomorrow.

"Castiel" he sang to him and watched him stop and turn to look at him over his glasses.

"Yes?"

"You are such a nerd! Why don't you come over here and watch the game with me?" he cried.

Castiel sighed deeply turning back to his work.

"I have a paper due in and you know this"

"I still can't believe you enrolled for college, I mean, I.C.T? It's daft"

Cas sighed and continued to type ignoring him, Dean gave in and with a huff turned back to the TV. "Just because you are in a stable job as a mechanic does not mean I can't get a successful job"

"Ouch, are you saying I am not successful?" Dean said in mock hurt.

He smirked as he typed away and felt a cushion hit the back of his head.

"I am successful!" he cried loudly.

"I didn't say you weren't! Watch your game, you are such a child sometimes" he muttered.

"I am 23 years old give me some credit, I'll grow up when you grow up"

"I am grown up!"

Dean rolled his eyes sipping his beer; he turned back to his game with a sigh.

"What has the lovely Anna got to say about this?"

"Nothing, she supports me like any room-mate would, unlike some" he muttered as Dean turned towards him shocked.

"I do! I'm just saying it is slightly daft that's all; don't go all huffy on me Cas"

Castiel ignored him and carried on working.

Silence grew between them for a good 20 minutes when Dean stretched loudly and went over to stand next to him.

"I need to tell you something…I want you to promise me you will keep it a secret because it is only an idea".

Castiel swallowed hard glancing up at his excited expression.

"What?"

He pulled something out of his pocket and passed it to him with a wide grin. Castiel looked down at the small box in fear, he knew what it was going to be and his heart nearly stopped in dread. He opened it to reveal a crystal white diamond engagement ring.

"Are you proposing to me, Dean?" he said in a small voice but looked up at him with amused eyes to tell him he was joking.

"No, don't need to, you are already mine" he said with a sly wink. "No, this is for Lisa…it's our 2 year anniversary next week and I plan to make her the proposal she will never forget".

Castiel cleared his throat feeling his heart pound loudly in his chest. "Wow, she…she will love it"

"No mentioning this to Anna! Understand me? She will tell her since them two are thick as thieves"

"Not a word" he whispered handing it back.

Dean glanced up at the time and grimaced in shock, he hadn't realised.

"Shit, its 6 already? Gotta go!" he said ruffling the top of his hair playfully.

Castiel swatted him away and smiled forcefully as Dean whistled a tune walking out of his flat. He looked down at his keyboard feeling his heart clench painfully at the thought of him settling down.

Dean and Lisa met 2 years ago after he helped mend her car one day, he never expected it to reach this moment but it was here and he hated it.

Anna walked in at that moment returning from work.

"Hey you!" she cried with a big smile and kissed his cheek as he greeted her.

"How was work?"

Anna collapsed on the sofa with a wince whilst taking off her high heels. "So tiring, who knew running around after business men would be such a task! I mean seriously, why am I secretary to these dicks again?"

"Because you love your job" he stated.

"Yes, remind me why?" she muttered and laughing to herself.

She suddenly sniffed the air and nodded. "Was Dean here? I can smell that aftershave"

"His aftershave is nice" he said with a frown and then realised how it sounded.

Anna smiled knowingly and nodded at him. "I know… how are you doing with that by the way?"

"Anna" he warned.

Anna had found out his secret whilst interrogating while he was drunk, he spilled the beans about everything and she wouldn't let it go.

"I just want to know! I care about you and you are harbouring very deep feelings for the bloke now, aren't you?"

"Yes! But they are invalid and not of import anymore…"

"Why?"

He shook his head and saved his work before slamming the screen down with a loud bang.

"He told me not to tell you"

"What? No, no, you cannot say something like that and shut me out! I promise with everything I own, I won't tell a soul"

He grimaced and stared at her for a long moment, she batted her eyes at him.

"Fine! He is proposing and I will know if she finds out!"

Anna gasped and squealed underneath her hand.

"I'm sorry for you of course but so happy for them!"

"Same" he whispered.

Anna sighed and stood up wrapping an arm around his shoulder. "I am sorry Castiel, really I am, but…maybe it's time to move on"

"Move on? Anna, I have been trying for nearly 7 years! Is it my fault I fell in love with him? I can't…I can't help it, he's everything" he whispered brokenly.

She wrapped her other arm and hugged him close. "Oh sweetheart"

He sighed and hugged her back. "How did it come to this?"

~0~

"Lisa? I'm back!" he called as she smiled at him from the kitchen.

"Hey babe! You hungry?"

"Starving"

He sat down and watched as she served up his favourite ham burger and chips.

"You are a darling" he muttered biting a big chunk out of it.

"I know" she said smirking.

She sat in front of him and picked at her pasta watching him closely.

"So where have you been?"

"Cas' all day" he murmured swallowing his food.

"Speaking of Castiel, I was thinking…"

"Oh that can't be a good sign" he grinned as she kicked at him.

"Shut it, no, I was thinking of match-making"

He stopped at that and looked up at her. "Match-making?"

"Yes! I mean, Dean, the guy hasn't had a girlfriend in over 2 years! When was the last time you seen him date one let alone talk to a girl!"

He swallowed and stared at her for a long moment before shrugging and noticing his stomach had turned horribly at the thought of Cas being with anyone. Yes, he had noticed he hadn't been with anyone else but he kinda liked it that way.

"But he's fine"

"Dean, no he isn't, he needs a woman and not Anna at his beck and call! I will find someone for him" she said determined and happily ate her pasta.

Dean dropped his burger and bit his lip listening to his heart scream internally NO at him.

"He's your best friend though? Doesn't he deserve to be happy?" his brain told him making him silently agree even though the thought still made him ill.

That night he walked into his local bar and greeted Jo warmly.

"Hey" she said handing him his usual. "Where is Cas?"

"On his way" he muttered and heard the door open to see him stroll in.

Dean smiled at him warmly and slapped him on the back gently.

"Finished that paper?"

"Nearly, why did you call me? Miss me already?" he said playfully grabbing his beer and swallowing it down.

"Oh of course" he said laughing and looking down at the bar. "No, I wanted to warn you against my girlfriend"

"Why?" he said fearfully.

"She is match-making!"

He blinked at him confused looking to Jo who shrugged as she stood in front of them interested.

"For you! She brought it up before"

"I…I don't need someone to match-make for me, no, Dean tell her I said no!" he protested biting his lip hard.

"But, why? I mean she is right, you do need a girl"

Castiel shook his head and looked away from him wishing he could tell him that he didn't want a girl because he didn't find them attractive at all, he was into men, one in particular and one he could never have.

"Because I don't want to date!" he hissed at him.

"Why?"

"Dean, you can't force him to" Jo said intervening as she saw the anger rise in Cas' eyes and his knuckles whiten.

"I'm not! We want to help"

Castiel scoffed dropping his beer and stood up.

"Whoa! Where are you going?"

"Away from you!" he cried slamming out the pub.

Dean looked to Jo who stared back in equal shock. "Did I say something wrong?"

"No idea, go after him though"

Grabbing his jacket, he rushed out after him and saw Cas hurrying up the road in the distance.

"Cas! Wait!" he shouted running up to him and grabbing his arm. "What the hell dude! Did I do something wrong?"

"No! Leave me alone, Dean" he cried tugging his arm away and glared at him.

"Was it the match-making shit? Okay, I'll tell her, but there is no need for the dramatic exit and this shit Cas!"

"You don't understand and that is the problem! You never fucking will" he shouted angrily at him.

"What?" he said taken back by his sudden outburst of anger.

"If I wanted to find a girlfriend or someone to date, I would! I do not need your help or Lisa's at all understand?"

Dean nodded quickly desperate not to leave this in a fight, he hated more than anything to argue and fight with him.

"I'm sorry, okay?"

"Yes" he whispered looking down at his feet.

The silence grew between them until Dean let out a frustrated groan. "Come here"

He pulled him into a tight hug holding him in his warm embrace; Castiel leaned against his shoulder breathing in the smell of his cologne, oil and leather. This was his favourite smell of all because it was, Dean.

Dean rubbed a hand up and down his back before letting go and looking down at him.

"I better go, call me tomorrow yeah? Don't leave here hating me"

"Impossible" he murmured letting go of him.

"I know, right, see you tomorrow" he cried and walked back the way he came, Castiel again watching his retreating back with a heavy heart.

He could still smell him on him and his heart beat a broken beat again, he hated this feeling more than anything. Love hurts, it really, really hurts and he wished he didn't but there it was.

He was hopelessly in love with his best mate Dean Winchester and once you fall, that's it, there is no going back.
