Preview: Urushihara doesn't get along with anyone; that's why when he started taking an interest in the new neighbour, he surprised even himself. A new friendship and a budding romance is enough to make anyone happy, but does he deserve happiness after everything he's done? M for later chapters

AN: Alright, so I've been planning this fanfic for awhile now to be honest. I am so obsessed with my OC x Lucifer pairing that I can't even be bothered to think of anything else. I ship this paring so hard that it literally hurts to know my OC isn't a real character... is that bad? I've even contemplated starting a petition to have her put in the series... Okay... enough fangirling. I hope you fall in love with this pairing as much as I have XD ~ Enjoy 3

Chapter 1: Our weird neighbour

click click click click...

The sound of fingers typing quickly on a keyboard echoed through the silent apartment, drowning out any hope for peace and quiet. With every finger tap that was made came a small clicking noise that resonated throughout the entire room; the sound being annoying enough to drive even the sanest person mad. The apartment was small in size; an average apartment for low-class living and extremely clean, yet empty, consisting of only a small table in the middle of the floor, a small kitchen, a door leading towards a very cramped bathroom, a small book case and computer desk with a laptop. The floors were lined with bamboo mats and bright green curtains hung down in front of the windows, blocking any sunlight from entering the room. A small-statured male sat at the computer desk, one of his purple eyes fixated on the screen as he played an MMORPG, rapidly tapping on the keyboard as he typed commands for his characters to follow while his other eye hid behind his long, dark purple bangs as it covered the one side of his face. He stopped typing only for a moment to reach his hand into a bag of potato chips bag, putting out a few chips to pop into his mouth before going back to typing; ignoring the greasy marks he left on the keys. The boy was clad in a loose-fitting white tee with pale purple sleeves and purple trimming with black gym shorts that had two red stripes running down the side of material; the perfect outfit for someone who stayed at home all day not socializing.

Some activity outside his door caused him to finally pull his eyes away from the screen and turn around. He gazed over at his door for a moment, listening to the strange voices outside before standing up and making his way over to it, opening it slowly and peering out into the hallway. Two large men carrying boxes walked past his door the moment he opened it, disappearing into the house that resided beside his. He watched as the two men emerged from the apartment and waited for them to leave the building before making his way over to the apartment next door, leaning against the door frame and peering into the room. He looked around the dim apartment in confusion for a moment before stepping in uninvited and looking around.

'Did Suzuno by stuff online?' He wondered silently to himself, gazing around the apartment as he looked for the blue-haired female. 'I didn't strike her as the type to buy things online, especially this much stuff.'

He walked further into the apartment, eyeing the boxes as he went, secretly wondering what were in them. Unable to contain his curiosity any longer, he turned towards the closest box and began to pull it open, ignoring the loud sound he made as the tape ripped away from the cardboard. He peered inside the box once he had it open and blinked curiously at the contents. He straightened up as he lost interested in what was in the box and made his way over to the next one. He was about to rip that box open as well, but a figure caught his eye, causing him to stop.

"Hey! Suzuno, what is with all this stuff?" he called, turning towards the figure he had seen in his perpetual vision, resting his hand on his hip. The figure stood in the open doorway, gazing into the house. Whoever it was lingered there for a moment, standing in silence. It took him a moment to realize that whoever was standing there wasn't Suzuno like he had initially thought.

A small girl stood in the doorway peering in at him, her arms held up to her chest protectively. She took a step towards him, being careful not to step too close.

"W-Who are you?" she called to him, keeping a lot of distance between them.

Urushihara blinked and let his arm fall to his side. He took a step closer to her, trying to get a better look at the strange girl. She appeared to be a bit shorter than him, which was strange since he was abnormally short, and was clad in a black sweater that exposed her shoulders, a white pleated skirt with thigh-high black stockings and white boots. Her long black hair reached the mid of her back with black bangs that swept across her forehead and a large white bow in her hair. It obvious that the girl wasn't Suzuno, and it left him feeling completely confused. He felt his body tense up as his awkwardness began to kick in, shifting uncomfortably where he stood.

"I... um... I..." was all he was able to manage, unsure what to say to the strange girl.

"Why are you I-in my a-apartment?" she stammered back, struggling with the question. It was apparent that the girl was just as equally and nervous and shy as he was. He was taken off guard by her question, looking over at her with a confused expression.

"Huh? Your apartment?" he asked in confusion, taking another step forward. The girl took a step back, leaning back up against the door frame. She cowered slightly as he took another step closer, causing him to stop moving entirely as to not frighten the girl.

"I... I just moved in... so...um... please don't rob me... I don't have much," she said, her tone soft despite her obvious nervousness, causing him to become even more confused than he already was. He couldn't recall Suzuno moving out of the apartment building, but then again, he didn't know much about anything since he cooped himself up in the apartment all day long. He put his hands up in surrender and looked over .

"I... I am not going to rob you," he said awkwardly, making himself sound more like a criminal than anything else, "my friend used to live here and I didn't know she moved out. Um... can I leave, or are you holding me hostage here?"

The girl seemed to tense up as he spoke, unsure whether to believe him or not. Awkwardly, she moved away from the door, keeping her eyes on the male. He slowly approached; trying not to startle her before exiting her apartment and walking out into the hallway. She immediately shut and locked the door behind him, making Urushihara hang his head in shame. He honestly and truly felt like an idiot as he stood outside her door, but after a moment, he headed back over to his apartment, his head still hung as he walked in shame. He opened the door and stepped in, blinking at how bright the room was. He recalled having had the lights off when he first left, but decided to ignore it. He slipped his sandals off his feet and entered further into the apartment.

"Where were you?" a voice asked, causing him to jump up in surprise. He moved his eyes to gaze upon the light-haired male that sat at the table staring back at him.

"Over at the neighbour's, dude... Why didn't you tell me Suzuno moved out?"

Ashiya looked over at the much shorter male, giving him an incredulous look before shaking his head and turning his gaze back over to the book he had been reading prior.

"I told you many times, Urushihara, but you were too busy with your computer. She even said goodbye the day she left and you just grunted in response."

The purple-hair male stood there for a moment, trying to rack his brain but to surprise (not), he had no recollection of that ever happening. He shrugged it off though, not really caring too much about being out of the loop. She was a nice person to be around sometimes, he could admit that, but they had never really been close so the loss didn't matter too much to him. She was more Ashiya and Maou's friend than she was his anyways, just like everyone else that seemed to hang around.

"Whatever dude, it isn't like it bothers me or anything, I was just shocked when I walked into the apartment next door, expecting Suzuno to be there, then finding out it was some other random chick living there," he told the other male nonchalantly, making his way back over to the computer.

"There is another tenant living next door now?" Ashiya asked in surprise. He hadn't heard any word about any new people moving into the building from the landlord, so he was thoroughly surprised to hear the new news.

"Yeah, some black haired chick; I scared her because I walked into her apartment. It's cool though, I was able to get some magic from her."

Ashiya looked over at him and shook his head in disgust, sighing at how un-classy the other male was. He was about to open his mouth to speak when the sound of someone knocking on the door cut him off. He looked over at Urushihara who had turned to look at him. They exchanged a few glances before Urushihara sighed and stood up.

"Don't get up or anything because, you know, someone knocking at the door is not something you get up for," he grumbled, making his way over to the door and opening it up. Standing in the doorway was the girl from next door, standing nervously in front of his with a cake in her hands. His eyes immediately when down to the cake, secretly hoping she had brought it over for them. He could feel his mouth water as he imagined eating a piece of it.

"U-Um... I brought this over... for...for..." she began, stumbling over her words as she shyly tried to justify why she was there, "... you and everyone else... it's... um... a welcoming gift... um... PLEASE DON'T ROB ME!"

The girl's sudden shot made Urushihara jump back in a panic, looking up at her with a wide-eyed expression. She pulled the cake close to her chest and turned away from him, bolting back to her apartment and shutting the door. Urushihara stood in the doorway, a dumbfounded expression plastered on his face. He stood there for a moment, trying to figure out what had happened before turning around slowly and walked back into his apartment, shutting the door behind him.

Ashiya had looked up from his book when he had heard the girl scream, looking over at them with a confused looked drawn on his face. He watched as Urushihara turned back around and shut the door, giving him a strange expression.

"What was that all about?" he asked in confusion.

"I am not entirely sure..." Urushihara admitting, rubbing the back of his head, "The next door neighbour brought us over a cake apparently and then she stole it back, but not before yelling at me not to rob her..." He sat back down at the computer desk, propping his elbow up on the surface and resting his head in his palm. He stared at the blank computer screen, replaying the events over in his head again, trying to comprehend what had happened. He felt a bit bad for scaring her earlier, but couldn't understand why she had been so jumpy when she came to the door. He shook his head, trying to push the thought out of his mind.

He looked up as the front door opened and watched as Maou walked into the apartment, a cake in his arms. The dark green-haired male looked down at the cake in confusion before looking over at the other two men who watched him.
"Someone left this..." he said, holding the cake out to show the other two.

Urushihara jumped to his feet, his finger pointing at the cake in Maou's hand.

"Did that neighbour give it to you?!" he asked loudly, causing Maou to give him a look of confusion.

"No..." he said slowly.

"That's the cake that the new neighbour brought!" Urushihara said, walking over to where Maou stood and took the cake out of his hands, looking down at it while Maou looked over at Ashiya, clearly confused about what was going on.

"Urushihara scared the new neighbour, she came over with a cake of us as a welcoming gift, got scared and stole the cake back. I guess she brought it back and left it outside," Ashiya told him, summing up everything that had happened.

Maou looked down at the cake in his hands then looked over at Urushihara, giving him a strange look.

"Our neighbour is weird..."
