William grimaced and let an annoyed sigh slip from his lips, fed up beyond belief with his coworker. He was used to Grell skipping work. He did it often enough, it might have been part of a routine for him. Sleep in like a lazy ass, make sure your ass is as high in the air as it can be when William T. Spears is forced to step inside and get you up, and proceed to cling onto his arm with a vicious grip as you follow him to work, a merry grin on your face all the while. William swore Grell had to have this ridiculous plan written down somewhere..

Adjusting his glasses, William picked up his pace, eyes gazing down upon the streets of London as he hopped across rooftops at an inhuman speed. This time, however, Grell would have to receive more severe punishment than a few stern words (which he ignored) and a smack across the head (which he whined nonstop about), no, Grell Sutcliff had been absent a record 15 days, and the department was now requiring William to hunt him down. With Grell's psychotic tendencies, very visibly serious death threats to the rookies, and viciously evil death scythe, they had been more than a little concerned when they learned he'd up and left without notifying anybody. William had gone to check his home, and, surprisingly, he wasn't lounging there. In fact, it looked as though he'd been gone quite a few days, from the state the rooms were in.

So, William had been sent out to search for him, much to his disdain. Honestly, if they were so disturbed by his disappearance, surely they'd be willing to go after him themselves.. But it was a direct order from his superiors. William couldn't just ignore it. No, he wasn't Grell Sutcliff, he was a better worker than that.

Coming to a stop when he reached the busy center of London, William carefully hopped down into an empty alleyway. He'd have to use the streets here, it was far too risky to hop across the rooftops when there were so many humans milling about.. Sighing as he straightened his coat and adjusted his glasses, William nodded slightly to himself and stepped out onto the main sidewalk, starting to walk again, keeping a careful eye on the humans around him. As though he'd be difficult to spot..not with all that re-

William's thoughts were cut off as something slammed into him, knocking him to the ground and causing his glasses to fall onto the concrete. Despite himself, William let out a weak-sounding gasp, damning himself for it even though it was justified. The Something on top of him's weight shifted several times before he heard someone fumbling around, and the cool metal of his glasses reached his face once again rather suddenly, and he turned to see his attacker with a slightly annoyed sigh.

The man was small, perhaps as much, if not more so, as Grell was. He had a round, very cute face, accentuated further by his dark brown hair tied back into a low ponytail with a plush pink ribbon. His wide green eyes darted around as he continued to look utterly apologetic and distraught, obviously quite sorry for knocking William over. His mouth, slightly parted, showed straight, white teeth, though he seemed to try not to show them when he spoke.

'He's just like a mouse.' William couldn't help but think, an unfamiliar warmth rising to his chest.

No. Oh, no.

Ba-dum, ba-dum.

Was this...was this what they called a crush? Love, even? He knew Grell had always ranted about "Love at First Sight" and similar topics, and William had listened closely even if he hadn't made it obvious, as he would have liked to know if they were true, but he had never thought such things would happen to him.

Still, here he was, face slightly flushed, heart beating heavily as the feminine man in front of him continued to squirm and stare at him pleadingly. William managed to compose himself after a moment, closing his eyes and clearing his throat to get his words straight in his head. "I'm perfectly fine, sir..but would you mind getting up off of me?"

William opened his eyes once again as the man squeaked another apology and stood, still kneeling next to William. William took the hand that was offered to him and let himself be helped up, brushing off his clothing and adjusting his glasses. He saw the man nod when he was proven to be alright, kneeling back down to gather something. The brunette noticed with a slight wince that he was putting together what he assumed to be purchases from shopping, several bags worth, and he went over to gather the items near another bag.

"Ah!" The small man called after him. "Ah, sir, you don't h-have to, I've got it.." The voice sounded somewhat familiar, yet entirely unfamiliar at the same time. His voice was high-pitched, though fairly quiet, and his anxiety was quite obvious in every word he spoke.

William simply shook his head, walking back over when the bag was gathered. "..It's no trouble, I wasn't looking where I was going, and I'd hate for you to be stolen from.." Thinking for a moment, William came up with a plan. Considering his search plan hadn't worked out so far, and the fact that Grell could not only move nearly twice as fast as him when threatened but could also be anywhere in London, it wouldn't hurt.."Allow me to help you carry them, Mister.."

The man seemed immediately flustered, panicked even, a dark blush adorning his face as he ducked his head, hands twitching nervously and tightening on the bag in his hands. "I-I...I-If you want to you may..I..my name..It..I-Isn't important.." He stammered, shaking his head a bit, presumably to try to collect himself. "I'm only a butler..So..I-I'm hardly ever called by name anyways..So..You can just call me..Mister or whatever you prefer."

William raised an eyebrow at him, thinking for a moment before smiling slightly as the man seemed to calm down, no longer shaking or looking terribly scared, though he did still have an ever-present shy look. So unlike Grell..William found it adorable. "Souris? Would it be alright if I called you Souris?"

Owlish eyes blinked up at William, a thin eyebrow raising slightly before a smile broke across the smaller man's face, his eyes lighting up like the emeralds they had the color of. "..You speak French, then?"

William shrugged. "Only some basic phrases...I have a coworker that goes off into rants in French if he gets irritated, and I thought it would be useful to know the language, and see if it calms him down more..I haven't had the chance to try it, though." William explained calmly, watching as the man let out a small giggle.

"So you're going to be calling me a mouse?"

"...You resemble one. Not like the revolting rodents that tend to roam Whitechapel, though..The way mouses are drawn in picture books." William blushed lightly, forcing the word which he would never use to describe anything before he met this man. "...Cute."

Souris's face lit up a rosy color, nodding as he reached his hand out for William. "..If..we're exchanging compliments, you're quite handsome. Souris is fine..I love it. And you are?"

"..William. William T. Spears." He offered, entwining his hand with the younger man's, though he was quite inexperienced with any physical contact. Thankfully, Souris didn't seem to mind, squeezing his hand lightly as he led William toward the manor.

"Thank you, William..The manor is a bit far away."

"I don't mind. I've not much to do, and you look like you'd need some help carrying everything."

Souris shrugged lightly. "..I'm used to it..My madam isn't a slave driver by any means, but I am her butler, so I do have to do quite a bit of everything for her...though.." The man bit his lip a bit, and William's eyebrow rose in his own show of concern.

"Though..?"

"I hardly ever get praise. Usually it's just a slap to the face, but, I do deserve it..I'm..incompetent beyond words and horribly unskilled at anything." Souris admitted, glancing up at William. "I'm earnestly surprised she still allows me to work for her.."

William could only stare at the smaller man, a horrible feeling of deja vu rising in his stomach. That couldn't be the way Grell thought of him, could it? No, he was always smiling, flirting, no matter what, there was no way he could be sad..

But, with a sickening twinge of guilt, he realized Souris had been just a moment ago, too. William honestly couldn't remember the last time anyone truly praised Grell, and he couldn't just deflect all the harsh words and actions like a human shield for his heart... That couldn't be why he had run away without a word.

But William had a feeling that what he was telling himself was all too wrong.

========================================================================

And that's chapter 1! More of a prologue or introduction than anything, but I still quite like it regardless.

If you aren't able to guess, Souris is Grell in his butler disguise. And souris does translate to mouse in French. I thought William would probably be able to be a casanova as such, but only for a moment.

Now, as far as updates go, I will try to update this fanfiction fairly quickly! As I write this, I have about half of this story actually done and completely written up. Due to this, I will try to update every day or every other day, depending on how quickly I am able to write upcoming chapters. As I only have one other end-of-year test coming up in about three weeks, I doubt school will get in the way of my writing, though writer's block is a different beast entirely. The first few chapters will almost definitely be updated within a day of each other, but I might start leaving a day's space when the story begins to pick up. I can't give you guys a cliffhanger and not use it to my advantage. ;)

I hope you guys all enjoyed, please rate and review if you have the time! Those are the two biggest things you can do to encourage me!
