Hello again! As I promised here's a multi-chapter malec AU. This is a very short and hopefully sweet fic. I've had this idea in mind for some time and I decided to explore it. For this fic I will be following the TV show dynamics so keep that in mind. I'll still use some stuff and characters from the books, but the interaction between Magnus and Alec (plus the other characters) will be more show-like.

Anyway, this story is different from what I've written so far. I usually write 4-5 scenes per chapter when I'm writing multi-chapter fics to help explain the plot and stuff, but I think that this story doesn't need it and therefore each chapter will have just one scene (1K to 2K words). The plot is quite simple, so I hope you like it. I will be updating the tags and characters as the story progresses, I don't want to spoil anything just yet.

Enjoy!

Chapter 1

College life was good and Alec loved it, well, he loved it most of the time. He was an English major at the University of Idris, one of the most prestigious universities in New York City. People referred to it as the new Yale, and Alec couldn't be prouder to be one of its privileged students. It was the best thing that had happened to him in a very long time and he was grateful for the opportunity he had received.

It was like a dream come true, but just like in any dream there was this small detail that threatened to turn it all into a nightmare; and that detail was Alec's roommate: Magnus Bane—Fashion Design student, eccentric extraordinaire, and the human version of a headache.

Alec hated that guy with all his soul. He was cocky, self-centered and loud, very, very loud. There were times when Alec just wanted to throw him out the window or punch him in the face, anything to silence him.

It hadn't always been like that, though. At first Alec had actually liked Magnus, like really, really liked him. His first impression of the guy had been that he was...well, easy on the eye, but mostly a nice person. Magnus was weird and quirky, with all his colorful clothes and bizarre makeup, but Alec couldn't deny that despite all that, he actually liked him.

During their first week they had talked about everything and nothing. They had asked each other all sorts of questions, some of them personal, some other trivial, but all seemed to be fine between them. Well, as fine as it could be between two people who had just met and were bound to live under the same roof for months. But then, after a week or so of knowing each other, Magnus had started to flirt with Alec. Alec didn't have a lot of experience in that field; he had just come out to his family about a year ago, so it was safe to say that he hadn't experienced a lot of dating during high school. In fact, he hadn't experienced it at all. So naturally, when Magnus had started to show some kind of more-than-friends interest, Alec hadn't known what to do and he had found himself just trying to go with the flow and laughing at Magnus's silly attempts to hit on him.

At first Alec had liked the attention Magnus seemed to have on him. He was always asking him questions, some of them plain stupid, some others quite personal. Magnus could go from 'how was the weather' to 'what was Alec's biggest ambition' in the blink of an eye. Alec answered some of them, some others, he just remained silent. Alec knew that he was awkward. He had always been, that was nothing new. He loved to read and get lost in his books. He had never been much of a talker, he considered himself a solitary man, but Magnus didn't seem to mind any of that, on the contrary, he seemed to actually like all that about Alec. Magnus seemed to understand him on a level that Alec didn't even think it was possible. He gave him his space, he didn't interrupt him and most importantly, he made Alec feel special.

For a couple of days Alec felt like walking on clouds. For the first time in all his life there was a hot guy who was interested in him, and Alec liked that. He liked that very, very much. Until well, he realized who Magnus Bane really was, and everything changed.

Alec never felt uncomfortable with the flirting game Magnus was playing. He liked it. The problem was that his roommate did that with, literally, everyone on campus—boys and girls alike. Magnus Bane was the biggest flirt to ever flirt on this planet, and Alec hated him for that. He hated him for making him feel special even if it was only for a couple of days. He hated him because he was so open, and free, and extravagant. And he hated him even more because he no longer looked at Alec like he used to.

It had been two months. Two months, and what at first had seemed to be the beginning of a very good friendship now was, well, Alec didn't even know what it was, but of one thing he was sure: they couldn't stand each other. They literally fought all the time. Day and night, they were always fighting. Magnus loved to make fun of Alec's lack of social life, and Alec found extremely enjoyable to just make fun of Magnus in general. He criticized his appearance, his extravagant clothes, his voice, and even his personality. They simply couldn't remain silent for more than five minutes. Slurs went back and forth between them naturally, almost like breathing.

"Where's your oh-so famous roommate?" Izzy, Alec's sister, asked.

His siblings were visiting him. They had had a day off from high school and had decided to pay Alec a visit in the dorms.

"I don't know and I don't care." Alec muttered.

"Is this his?" Jace, his brother, asked, picking up a funny-looking hat with golden glitter all over it. Jace had been snooping around the room since they had returned from their tour through the campus. He had found extremely hilarious how the place was perfectly divided into two.

The room was not big, but it was spacious enough to allow each of its inhabitants to have some kind of personal space. The left side was covered from floor to ceiling with colorful posters and shiny ornaments. The right side, well, it was safe to say that it stood out for its cleanliness and order. There was a large bookshelf with thousands of books and a very well-organized desktop. It was obvious, to anyone who entered the room, that the two people sharing it were completely different. Like fire and ice, like day and night.

"Yes, it's his. And if I were you, I wouldn't be touching any of that. You'll just end up covered in glitter. All his stuff is so…glittery." Alec said, failing to find a different word to describe his roommate's stuff.

"Evidently." Jace said, putting the hat back where he had found it and moving on to snoop around Magnus's other belongings.

"I want to meet him." Izzy said, taking a seat on the edge of Alec's bed. "I mean, he's your sworn enemy, right? If something happens to you, it would be better if I knew who I have to punch."

Alec laughed. "He's harmless, Iz." He said. "I can take care of him if he tries anything, I am taller than him."

"Alec, no offense," Jace said, "but you're taller than almost everyone."

It was true. Alec was tall, like very, very tall. His more than 6' 2'' tall were definitely not average height.

In that moment the door of the room opened and a very dazzling Magnus walked in. He was wearing a blue shirt with glittering silver patterns. His hair had matching blue locks, and his eyes were perfectly outlined with soft touches of a sparkly dark blue eye-shadow.

"Having a little party and you didn't invite me, Alexander? How rude of you!" He exclaimed mockingly.

Alec didn't reply and just rolled his eyes, trying to show his discomfort with the arrival of his roommate.

"I'm Alec's sister, Isabelle Lightwood, but you can call me Izzy. Nice to meet you." Izzy immediately said, greeting Magnus with a lot of familiarity. Not that that surprised Alec, his sister was like that all the time.

"Well, the resemblance is striking." Magnus said. "Nice to meet you, Isabelle. I'm Magnus, Magnus Bane." He added, greeting her by the hand.

"Can I just say something?" Izzy said. "Your eyeshadow is so on point, I love it. And that shirt...well, it really fits you. I love your outfit!" His sister exclaimed, being her usual friendly self.

"Why, thank you...I can see that you have good taste in clothing too. I love your outfit. Dressed to impress, I like that." Magnus said.

Izzy grinned pleased with the sudden compliment and Magnus winked at her. Alec was hating this newfound relationship. Magnus was Alec's nemesis and therefore his sister should be trying to bring him down and not to become his friend.

"And, you are?" Magnus asked, noticing Jace.

Alec could see that Jace looked seriously confused with Magnus's personality. He had a puzzled expression on his face, as if uncertain whether the person who stood before him was real or not.

"Jace. I'm Alec's brother too." Jace said, extending his hand in a polite way.

Alec saw Magnus frowning in confusion. Surely he was questioning how it was possible that a blond, blue-eyed guy could be Alec's brother. Unlike with Isabelle, Alec and Jace looked nothing alike.

"Adoptive brother…it's a long story." Jace clarified.

"I see…" Magnus said, already ignoring Jace, "then, I'll just grab my stuff and leave. I wouldn't like to crash this lovely family reunion." He added, quickly gathering his stuff and walking away from the room. "Nice to meet you all." He waved goodbye.

"Remind me again, why do we hate him?" Izzy asked, as soon as the door of the room closed behind Magnus. "He seems nice, and smart...plus, he's super hot."

"Izzy!" Alec exclaimed almost horrified.

"What? Don't tell me you didn't notice it. I mean, come on, Alec! You like boys, you can't be immune to his looks. From Jace I could understand, but from you? Don't disappoint me, big bro. You can't be «that» blind. You have to admit that he's hot. He's so…" she hesitated to find the word, "mysterious. Yes, that's it. He has this air of mystery that's extremely sexy."

"Well, sorry to disappoint you, but I do not find him attractive at all." Alec said, trying to sound sure of himself. Because he was sure of himself, of course.

"Do you have his number?" Izzy asked out of the blue.

"Isabelle!" Both Jace and Alec exclaimed at the same time.

"What? He's hot." She smiled, feigning innocence.

"Aren't you supposed to be dating Jace's girlfriend's best friend?" Alec asked.

"Clary, Alec, her name is Clary." Jace said, rolling his eyes.

"Well, her." Alec said. He didn't do it on purpose, but for some reason he always forgot the name of that little red-headed thing that followed Jace everywhere. "Aren't you supposed to be dating Clary's best friend?" He rephrased.

"His name is Simon, Alec, and yes, we are dating, but we're not exclusive." Izzy said.

"Well, maybe you should tell him that and remind yourself the same thing every now and then because you two act like real boyfriend and girlfriend, like all the time." Jace said. "You should have seen them yesterday, Alec. Clary invited us to see her art exhibition at her school and Izzy and Simon were all lovey-dovey the whole time. It was embarrassing. Clary and I, at least, showed some sort of self control, but these two?"

Izzy rolled her eyes. "Stop judging me, I'm allowed to have some fun. I like him, I'm just not sure if I want an official relationship at the moment."

"And, why is that?" Jace and Alec asked at the same time.

"When all this became a therapeutic session, huh? I thought we were talking about Alec's hot roommate and not my love life."

"We can cover both topics." Jace said.

"No, we can't." Alec intervened before his siblings could continue. He didn't want to discuss his roommate's apparent hotness or whatever. "I have homework to do and actually, now that I remember, I have to go to the library to pick up some books."

"Are you seriously asking us to leave?" Izzy asked offended.

"No, I'm just telling you that I have homework to do. You are more than welcome to stay and help me. In fact, I have to read and analyze three of Allan Poe's masterpieces. You can each help me with one and that way I can finish earlier."

Jace and Izzy looked at each other.

"I just remembered that we told mom we would be home early, right, Iz?" Jace said. "To help her with-with-"

"-to help her with Max." Izzy chimed in. "We are-we are...tutoring him. He's not doing so well at school, you know how our little brother is, he's all day reading those manga things and he never does his homework."

"Yeah, of course." Alec said with a smile. "Then, let me walk you out. We don't want you running late for your tutoring sessions with Max."

"We would have loved to help, you know that, right? I love Poe...one of my favorites." Jace said.

"Of course, Jace." Alec said, trying not to laugh. "Why would I think any different? It's not like you're practically running to avoid helping me with some poems."

Jace and Izzy gave him a look.

"What? I still love you. Even when you don't want to help me." Alec said.

"We love you too." Izzy said, hugging him. "We'll see you soon, okay?"

"Okay...have fun and behave, please!" Alec warned them. "I don't want mom calling me because you screwed up again."

"Us? Screwing up? I take that as an offense, Alec." Jace said with a smile. "We're the best behaved children in all New York."

"Yes, of course, especially you, Jace." Alec said, rolling his eyes at his brother. He couldn't even count how many times he had saved his sorry-ass in the past. There were troublemakers and then there was Jace. Alec still didn't know how, but his brother always managed to get himself immersed in the most dangerous and random situations. "Just be careful, okay?"

"We will." Jace said, walking out of the room.

"Bye, big bro...we'll talk soon, okay?" Izzy said, hugging him again. "And...I wasn't kidding. If you happen to have your roommate's number don't hesitate to send me a text."

Alec rolled his eyes. "You're impossible, Iz. Just get out of here." He said, laughing.

"On second thought? Keep it to yourself, maybe he's more your type than mine."

Alec rolled his eyes and closed the door of the room, trying really hard not to smile.

"He's not my type." He murmured to himself. "He is not."

Chapter 2 will be up soon ;) (probably tomorrow). Thanks for reading!
