The rest of his first week in school passed in a blur and before he knew it he was waking up to a brand new Monday morning. He had no more lessons with Dean till this day and up to now, Dean had been ignoring him. He was ignoring him, briefly speaking to him, and going in a different direction when he saw him.

Castiel walked into the classroom that early Monday morning to see Dean rubbing his forehead nursing a headache looking down at his desk. Castiel frowned sliding into his desk and staring at the man who was deliberately not looking into his direction.

All in all, his first week at Cardozo had been a nice experience, he was enjoying his time, he only wished he could enjoy a lot better.

"So, let's begin!" Dean said brightly to his class and turned his back to the blackboard. Castiel sighed slumping in his seat and turned his gaze to outside, it was a cold and miserable day matching his mood. Home was not a pleasant time at all with Gabriel constantly snapping at Anna who retaliated back with her own comments.

"Castiel, is there something outside more interesting than my lesson?" Dean said startling him out of his daydream.

"No…sir" he said with a raised eyebrow indicated only for him. Dean's eyes narrowed slightly before he started up his lesson again. Castiel sighed picking up his pen and lounging back rolling it across the edge of his lip and into his mouth; he barely noticed that Dean had set them to a task. He sucked on the end gently watching the rain fall slowly from the window till he felt green eyes watching him and turned to meet them.

Dean watched as the pen slid into his mouth and ran across the bottom lip slowly feeling dizziness and a weight in his stomach.

Castiel noticed and his brow furrowed confused to the nervous look in his eyes as he watched the pen.

Dean watched as he smirked and drew it out tilting his head to the side in question. He sniffed deeply looking down at the sheet and drew in a shaky breath.

"Get a grip" he muttered under his breath scribbling down furiously on a piece of paper.

Castiel chuckled under his breath; he was very confused but amused by this little turn of events.

He looked over the class to see Jo looking at him questionably. He shrugged at her and looked down at his work flipping open the text book and beginning.

Fifty minutes flew by and before he knew it the bell was ringing for next lesson. He sighed collecting his things together very slowly waiting till every person left before sliding up to him at his desk.

"Cas, how can I help you?" Dean said in a polite, formal, tone that made Castiel want to punch him hard.

"I was wondering if those extra lessons were still happening tonight."

"Yes of course, but only if you want too. I wouldn't want to take away your free time"

"No, no, I want this"

"Good, then I will see you again at the library" he said softly.

"I look forward to it" Castiel replied with a small smirk that made Dean's heart give a little jolt as he watched him walk out. The door clicked shut behind him and Dean pressed a hand over his eyes taking in deep calming breaths.

"What is happening to me?" he whispered opening his drawer and popping two pills into his mouth to numb the headache and hangover from last night. He hadn't meant to drink but the thought of coming in and having to look into those alluring blue eyes for a whole hour drove him to the beer.

Castiel ran down the corridor till he reached his locker and opened it up throwing his bag inside.

"It's a Monday morning, calm the fuck down" Pamela said noticing him.

"I am calm" he said taking in the sunglasses she was wearing indoors. "It's raining, Pamela"

"These lights kill my eyes!" she hissed glancing up and sighing. "Anyway, why are you so fucking happy?"

"I'm not, I just liked the lesson"

"History? The only good thing about that history lesson is when Mr Winchester bends over and I get a good look at that ass" she said with a sigh pulling out her bottle of water sipping it. "But apart from that"

Castiel hummed slamming his locker when a hand moved out to stop him.

"Wait, I was talking with Jo about you and we have one little question for our new friend…"

"Okay?"

"Are you gay?"

"What?"

"Only because you agree with us when we say that Dean Winchester is gorgeous, has a perfect ass, and it's totally fine with us if you are because…being gay is normal, I guess" Pamela said awkwardly shaking her curls. "Just…are you?"

Castiel scratched the back of his neck and shrugged. "Maybe…look I don't really want to discuss it"

"That maybe is a yes, well thank you for clearing that up" Pamela said with a relieved sigh. "I'll go tell Jo"

"No! Wait, Pamela…" he said trailing off when she walked away and swallowing nervously. Sudden anxiety picked at him and he turned his back rushing into the toilets feeling a wave of sickness. He hadn't felt this bad since it happened. Waves of pain, sickness, and the desire to block it all out just washed over him as he stared at himself in the mirror. His eyes had become wet and watery, and he let out a pathetic sound as he turned his back knowing he was now very late for lesson.

Castiel walked out of the toilets looking at the history door and wandered over to see if Dean was still there. He glanced inside to see him alone in an empty classroom reading something in his hand; he looked over at him to see he was wearing normal fitted jeans and a shirt over a t-shirt. Castiel sighed looking over the tanned skin and wondered just for one moment what it would taste like. Dean turned abruptly and caught sight of him and frowned.

"Shit!"

Castiel moved away hurrying down the corridor.

"Cas!" Dean called after him. Castiel ignored him as he turned to corner opening a door and hiding inside it to closing his eyes; he waited with baited breath listening intently for the sound of footsteps. He breathed out when there was nothing and glanced around to see he was in the janitor's closet.

"Typical" he murmured opening the door carefully and sliding out only to stop and stare at Dean. Dean was leaning against the lockers, arms folded, and waiting for him to come out.

"Coming out of the closet?" Dean said innocently but there was a flare of amusement in his eyes.

"Hilarious" Castiel said shutting the door.

"Why are out of class?"

"I couldn't stomach it, literally, I feel ill"

"Then why have you not gone to the nurse?"

"I was going too!" he snapped and felt guilty straight after when Dean's eyes narrowed.

"Sorry, I was going too"

"But instead chose to look into my window?"

Castiel flushed pink looking down at his shoes, Dean licked his bottom lip staring at the rosiness of his cheeks and felt a shame of disgust at how it made him feel.

"Go to class or go to the nurse, Cas"

"Class" Castiel said hurrying away without a backward glance for him. Dean watched him walk away as usual and sighed unclenching his tight fist and inhaled letting it out in a big puff of air. This was going to really test him.

~0~

The final bell rang and he sighed in relief when he realised he would be spending the entire hour with Dean doing history. Jo looked over at him as they walked out of art together.

"You have been a ball of sunshine all day" she commented.

"So?" he murmured with a smirk pulling his jacket around him tighter. "I rarely find something happy but when I do, I cling onto it"

"Okay" Jo said with a smile. "I'll see you tomorrow, enjoy history all over again"

Castiel nodded at her walking up the stairs towards the library, he glanced inside and looked around with wide eyes. It was huge with tables and chairs all around surrounded by computers and books.

"Cas" Dean said and he looked over to him in the corner. Castiel smiled at him before walking over and grimacing at the books on the table.

"You see this is why I hate history, all this reading" Castiel murmured picking up a book and throwing it down.

"I want to ask you a few basic questions" Dean said turning to face him. Castiel eyed the distance between them and nodded.

"World War 1?"

"1914 to 1918"

"World War 2?"

"1939 till 1945"

"Well done" Dean muttered. "When was Kennedy shot?"

"I don't know, do you know?"

"You are supposed to be answering the question"

Castiel smirked leaning on his hand looking up at him. "Was it you?"

"Was what me?"

"Did you kill Kennedy?"

Dean rolled his eyes pushing the book towards him. "It was in 1963 and no…it wasn't me, I'm 26 years old and was not even born"

Castiel smirked softly at him. "I have to say this, Dean, you are quite nervous around me"

"Oh really?" Dean questioned flicking through a book.

"Want me to suck my pen again?" he whispered into his ear and pulled back with a playful grin when he spluttered glaring at him.

"Are you just going to mess around teasing or am I just wasting my time being here"

"No, I'm sorry" Castiel said pulling the book towards him. "I just love history so much"

Dean raised his eyes to the heavens hearing his sarcastic tone and ignored the warm feeling flooding inside him, he liked Castiel, he was different, nothing like the other students and it unnevered Dean very much. Dean couldn't deny for one second that Castiel wasn't gorgeous, soft black hair, pale skin that flushed beautifully pink when he was embarrassed and the most beautiful blue eyes he had ever seen. So it was no surprise to Dean as he watched him closely that he wished he was older, he wished more than anything he was in his late twenties like he was and he could take full advantage of him.

Dean bit his lip not thinking of the consequences if he did otherwise. Castiel sighed flicking through it and looked over to Dean resting his cheek in his palm.

"What?" he murmured gently.

"Nothing, anyway, why are reading the Gulf War?"

"It's interesting actually and it's a recent war"

"If you are interested about the wars, read the world wars instead"

"I have, they are so boring, why don't you make it more fun" he purred in a teasing voice.

Dean gritted his teeth moving away and fixing him with a hard look. "Stop that"

"Stop what?"

"You know what!" Dean hissed at him pinching his bridge wishing he had taken some more headache tablets.

"I am doing nothing, Dean" Castiel said with a puzzled look.

"Flirting" Dean whispered under his breath.

Castiel blinked looking up and away from him amazed.

"You think I am flirting with you?" he whispered when Dean glanced at him.

"You're not?"

"If I was, would it be so bad?"

"Cas, stop it, okay?" Dean said feeling tired all of the sudden. "Now can we focus and stop playing these silly little games, I would remind you that you gave me an E essay and I am doing this out of the goodness of my heart"

Castiel nodded slowly leaning back in his seat listening to Dean as he cleared his throat and began talking about the First World War.

"I thought we were doing U.S history?"

"We are, well the class is, you are not"

"What? Demeaning me already!" Castiel said horrified sitting up a little straighter.

"The students in my class are working towards, A's and B's, Cas, I can't settle you on that just yet but we will get there" Dean reassured. "We have a good few months"

"You are sticking with me for a good few months?"

"Of course, Cas, I am here to help you no matter what. I will help you; I will get you that grade you want so much"

Castiel stared into the green abyss of his eyes feeling his breath against his cheek and bit his lip, Dean's eyes flew down towards it and back up to his shocked at what he had just done. Castiel could hear his heartbeat in his ears and swallowed hard forcing the nerves and the lump in his throat back down.

"Is he going to kiss me? Am I going to kiss him? Oh no, what am I doing?" Castiel thought when his own eyes looked down the full bottom lip and fought the urge to drag his teeth across it and kiss him hard. His stomach lurched at the thought and before he even thought what he was doing, who was looking, and the consequences, Castiel leaned over pressing his lips against Dean's.

Dean drew back immediately with a gasp staring at him with horrified and appalled eyes.

"What the hell do you think you are doing?" Dean whispered outraged looking around the library thankful to see it empty and they were hidden in the corner. "Are you…Cas, what the hell was that? I am your teacher!"

Castiel touched his lips and recoiled back knocking over his chair.

"I am so sorry, oh my…I am so sorry, Dean, I don't know why I did that" he lied grabbing his stuff and sprinting out of the library, down the stairs and out of the front doors not looking back till he hit the path and collapsed against an oak tree trembling. His heart raced, his lungs burned, and his lips tingled under his fingertips. Castiel closed his eyes in horror, he had just kissed his teacher, his older teacher, his mature, supposedly straight teacher who he liked the thought of and enjoyed teasing.

Castiel covered his face slumping to the ground and burying his head in his hands in shame and disgust.

"I'm disgusting" he whispered shamefully burying his face into his knees letting out a small whimper.

~0~

Dean returned back to his classroom dumping the books and running a hand over his eyes and stubble feeling like the biggest fool to walk the planet. A week into this school he was already thinking inappropriate thoughts that would get him sent to jail about a student, leading said student to extra lessons and now letting him kiss him. Dean rubbed his lips together and dropped down on the seat fearing a big mess in front of him.

"Ignore him, ignore "it", and ignore everything. Nothing happened and everything is fine, life is just normal" Dean said out loud to no one and nodded. He could live with that, he could live with the fact that only after a week he was breaking the boundaries plus the rules.

A text message alerted him and he pulled it out to see one new message from Sam.

Sam.

Hospital now! It's urgent, I think this is it, Dean.

Dean dropped the phone, grabbing his car keys, and hurtling out of the door towards the hospital forgetting Castiel for that one moment. It was a tiny bit of relief. This school year was set to be the biggest mess of his life or maybe the greatest. Who knew?
