A/N: I've decided I need to post some of my backlog of unfinished stories, and this is one of them. This story won't be updated with any sort of regularity; instead of being on a schedule like my main stories, it will be updated whenever I feel like it. Basically, I'll update it based on how it's received. If you like it, please review it; I'm more likely to work on this story and update it if I feel like people want to read it.

As stated in the description, this story is a Modern AU, Yullen, with a female Allen, and there will be lemons. This story is going to have much shorter chapters than my others - averaging 1000 words a chapter rather than 2500 or 3000. There will also be hints of LavixLenalee, but as of right now, I have no intention to take it any further than just hints.

Allison Walker sighed as she checked the time on her phone. She shoved her books into her bag, threw on her coat, and made her way out of the library. With any luck, she'd be able to get to class without any of her friends making her late.

It was a stupid wish as she had the worst luck of anyone ever.

Lavi just happened to be entering the library right as she was leaving it. The moment he saw Allison, the redhead threw one arm around her shoulders and used the other to tousle her short white hair. "Yo, Allen! Whatcha up to?"

Allison tried to shrug off the embrace, silently groaning at the reminder that she was only liked around campus because everyone thought she was a boy. "I'm heading to class, Lavi. I don't want to be late and piss off my lab partner."

Lavi laughed and tightened his hold on his friend's shoulders. "Good luck with that. Everything pisses off Yuu-chan. You're upsetting him simply by being his lab partner."

"Do you think I don't know that?" Allison snorted. "If I could get out of it, I would. I don't want to be Kanda's partner any more than he wants to be mine. The guy's got a stick up his arse."

The redhead smartly pulled away when the younger's British accent came out. It didn't surface very often, but when it did, it was a sure fire sign that Allen was angry. And when Allen was angry, bad things happened.

Allison frowned to herself as she stalked away from Lavi and began her trek to the science building. The redhead had reminded her of her ongoing feud with the hottest guy on campus, and she was not happy about that. Because all that did was make her think about her crush on said lab partner and how nothing could ever happen between them. Because, like everyone else on campus, Kanda Yuu knew Allison Walker as Allen Walker.

When Allison finally navigated the maze-like halls of the science building and reached her classroom, the instructor was already at the white board, going over the instructions for the day's lab. She managed to slip in unnoticed by the teacher, quickly finding her seat next to the tall Japanese man who had been glaring at her from the moment she entered the room. "You're late, Moyashi."
