A/N: This is based off a tumblr post that had a list of great AUs. This is a "sat down in the wrong class" AU.

Ryuko ran as fast as she could toward the science building, which happened to be a mile or so away from her apartment. She didn't want to be late on her first day of class, though sliding in half a minute before class started seemed to be what was going to happen. Luckily, the sidewalks were clear, making her run take less time.

The halls of the science building were full, making it difficult for Ryuko to navigate through. She glanced down at her schedule before entering the room to her right. It was a large lecture hall, though most of the students had already arrived, taking up every available seat. Except for two up front, both on either side of a woman sitting front and center.

Ryuko hurried to the front, taking the seat to the right of the woman. She glanced at her phone, two minutes before class, and the professor wasn't even there yet. That counted as a win, she supposed as she unzipped her backpack and pulled out her notebook. She sneaked a glance at the woman beside her, just barely stopping her jaw from dropping

Her hair was pin straight and her clothes, which may have cost more than Ryuko's books, were without a wrinkle. Her posture was perfect, too straight to be comfortable even. She wore a frown on her face as she stared straight ahead, her blue eyes cold and focused. She had sharp features and large eyebrows, though Ryuko had to admit that they complimented her face well. This woman was gorgeous. Ryuko didn't even know her name, but she knew that she hated this woman.

The woman beside her turned ever so slightly, her frown deepening at the sight of Ryuko's notebook. "You have the wrong room." She said in a monotone.

"What?" Ryuko hissed, her eyes meeting the other woman's cold ones.

"This isn't Math 215." She said, sounding impatient. "This is Business Law 323." She glanced toward the back of the room as the professor wandered in. "You have the wrong room." She paused for a moment. "You have the wrong building."

"Shit." Ryuko made a move to grab her bag, but the professor was already writing his name on the board.

The professor was old and looked like he didn't want to be there, something Ryuko was sure they had in common. But the glare that he sent the students made her freeze in her seat and open her notebook.

I guess I'm taking business law today. She thought bitterly, pulling out her pen.

Business law was the dullest thing that Ryuko had ever experienced. The professor droned on and on for nearly three hours, not even bothering to go over the syllabus that he was supposed to pass out. Ryuko hated him. She hated him, and she hated the woman beside her who seemed to understand everything that he was droning on about.

Ryuko turned and watched the woman beside her. Her eyes bore into the professor, looking through him rather than at him. She looked incredibly bored, but there was no doubting her attentiveness. Especially considering the speeds in which her pen flew across the paper of her notebook. Ryuko would have watched her more, if not for the fact that the woman spared her a glance. Which soon turned glare after realizing that Ryuko had been watching her.

Ryuko spent the rest of the class with her head down, only looking up to sneak a peek at the woman beside her. She was sure that the feeling in her gut was that of pure hatred, it had to be. Everything about the other woman was infuriating, even the way she held her pen. No. Especially the way she held her pen.

At the two hour and fifty minute mark, the professor set them free. He told them that they could pick up a copy of the syllabus on the back table, before hurrying out. Ryuko felt it wise to follow his example and made a move to escape, only to run head first into what felt like a brick wall… with pillows?

"Watch where you're walking." An authoritative voice snapped, making Ryuko look up. It was the woman who sat beside her during the class. She scowled down at Ryuko, looking as if the shorter woman were road kill rather than a fellow student.

"Watch where you're… standing!" Ryuko shot back, making the taller woman's brows furrow.

"That didn't make sense." She replied, her frown deepening as she moved past Ryuko. "Now, if you'll excuse me, I have to get my syllabus."

"Yeah, you do that." Ryuko said, mentally slapping herself at the taller woman stepped by her.

The other woman didn't seem to feel the need to respond as she walked away. Ryuko was strangely thankful for that as she watched her walk away.

Ryuko turned her heel and left the room, stuffing her hands in her pockets as she went.

The walk back to her apartment was quick enough, though it was nothing compared to her sprint to the wrong building. She hurried into her building and hopped into the elevator, there was no way that she'd be walking up seven flights of stairs. Her best friend and roommate, Mako, was still there when she opened the door. High School Musical was playing on their shared television.

"How was class?" Mako asked, not looking away from her movie.

"I ended up in the wrong building." Ryuko replied, sitting down on the faux leather sofa and frowning at the television.

"No math then?"

"Nope. Business law."

"Oh… that sounds awful." Mako turned to face Ryuko, a frown forming. "Did you make any friends? You were gone a while."

"It was a three hour lecture." Ryuko's frown deepened. "Three hours of boredom!"

"Terrible."

"And the chick next to me was taking notes all perfectly! She acted like it was the most interesting thing on earth!"

"Maybe it is for her?"

"No one in the universe is that boring."

"Sorry your class sucked." Mako leaned over and engulfed Ryuko in a tight hug. "But Troy and Gabriella get are about to sing their big duet… Will that cheer you up?"

Probably not. Ryuko smiled in spite of herself. "I'm sure it will."

"I knew it!" Mako turned her attention back to the movie. "Maybe tomorrow will be better…"
