Of course this was just her luck. Of all the damn times to have the fire alarm go off. Clarke had just got home to her small studio apartment not two hours ago from a shift at the hospital, when a blaring siren decided that now was a good time to wake the entire city. Clarke jolted out of bed, glancing at the time as she hurriedly pulled on a sweater and some sandals. The red glow of the digital clock on her nightstand indicated 3:06 . Just fucking lovely, Clarke thought.

Quickly locking her door, Clarke headed for the nearest staircase. Running down the six flights of stairs and out the door, Clarke was hit with a wall of cold air. It was mid-October in New York City, so it wasn't exactly the warmest weather outside, during the night.

Across the street, the other tenants of the apartment building were patiently waiting, arms wrapped around torsos attempting to block out some of the chilly autumn air. Clarke was walking over to the group of tenants when she noticed her neighbour, that hot new guy from apartment 6C, sitting on the sidewalk away from the others, and half nude. Well, if I wasn't awake before, I most definitely am now, Clarke thought.

She had to admit her new neighbour was extremely attractive; short and curly dark hair, really tall, a toned body, tan skin, warm brown eyes and a smattering of freckles was a downright dangerous combination. He just screamed rebel. And the fact that he was not ten feet away from her in nothing but a pair of plaid boxers was a little hard to ignore. Fully enraptured in her perusal, Clarke didn't notice he had seen her staring at him.

"Hey 6B! You like what you see?" her neighbour asked with a smirk, now walking toward her. Uh-oh.

Flustered, Clarke rolled her eyes, attempting to putt on a confident air. "More like, wondering how you don't have frost bite yet." she replied.

"Sure, Princess." he said with a wicked grin.

"I'm serious! Did you not have time to even grab a shirt? Or shoes?" Clarke exclaimed.

He just scoffed. "No actually I didn't. Why? You worried you won't be able to control yourself around me without a shirt on? I saw you checking me out earlier."

Exasperated and tired, Clarke just sighed, "You know what? Never mind. I was just trying to be friendly with my new neighbour, but whatever."

As it turns out the fire alarm had been a false alarm, so the tenants were already heading back inside. Clarke turned and began walking away from her half naked neighbour, when she heard footsteps catch up behind her and a hand reached out and grabbed her forearm.

"Hey Princess, I'm sorry. I didn't mean that. I can just be an asshole sometimes. Plus I think we're all a little tired and irritated. That alarm woke me up after I had just fallen asleep, and I hate getting my sleep interrupted. And to top it off, I'm freezing my ass off out here." Her neighbour was looking down at her with a genuine, shy smile and big, brown, puppy dog eyes - much different from his previous demeanor.

Clarke turned back to him, and let out a small laugh. "All right, one more chance." They began walking up the six flights back to their apartments.

At the doors to their apartments, he turned to Clarke. "Let's start over. Hi, I'm Bellamy Blake, your new neighbour in apartment 6C." Bellamy extended his hand to Clarke.

She shook his hand and replied. "Hey Bellamy. Clarke Griffin."

Bellamy smiled, "Not that I don't like the nickname Princess, but it's good to know you're real name. So Clarke Griffin, how about I buy you a drink Friday night, you know to make up for my behaviour earlier.

Clarke smirked, "Well, I did say one more chance, didn't I?" She unlocked her apartment and headed inside, leaving Bellamy standing in the hall grinning at her, still in his underwear.

Years later, lying in Bellamy's bed on his chest, Clarke smiled to herself thinking about the story they told to their families regarding the day they met, and how their (now) five-year relationship all started with a 3 A.M fire alarm.
