Kakashi briefly registered a blur of pink flashing by his periphery. He briefly debated between trying to see what that was all about or just staying in his seat at the campus bench as he sipped his coffee. He decided on the latter. Mah. Kids these days are too full of energy. He sighed as he continued to grade his students' papers.

Kakashi was roused from grading Uzumaki Naruto's essay on the health benefits of ramen by a loud crash. It came from the fountain where there appeared to be a fight that was slowly gathering audience. The participants were a guy that Kakashi didn't recognize, which was suspicious in itself as this was a small school and he knew almost all students at least by face, and Haruno Sakura one of the most brilliant students who ever darkened the doorway of his classroom.

He had her when she was just a freshman taking up General Sciences and he was still a new professor. She was still on the thinner side back then, still not yet engaged in campus athleticism that buffed her up into a lean and muscled form. From his seat, he saw her friends, Naruto and Sasuke, hauling off her now unconscious opponent in the direction of the disciplinary office. In Kakashi's opinion, they should have brought the poor guy to the clinic first, as Sakura's fist looked like discipline enough for whatever transgression this outsider committed. He watched her slowly crouch down to retrieve something from the asphalt that must have fallen off during her scuffle. Wearing gym shorts and a racer-backed shirt that showed off her well-shaped back muscles and toned arms, she must have been in the middle of training. Kakashi watched, mesmerized at the way the sun glinted off the sweat coating her skin, before shaking himself off the act of ogling his past student.

He was about to return to his work when he found Sakura herself right in front of him. So engrossed was he in watching her that he didn't even notice that she approached him. She was fidgeting and had this look of uncertainty on her face. Up close, Kakashi noticed that her cheeks were flushed and she was panting slightly, probably from all that physical exertion. He, himself, was starting to feel awkward at their situation as well, with her staring at him and him trying to keep his eyes off the corded muscle of her forearms. He cleared his throat. "Ahem, can I help you with anything?"

That seemed to rouse Sakura from her self-induced stupor. She turned slightly redder, before nodding and extending her hands in between them. Kakashi, who finally had an excuse to openly stare at her arms, looked down slowly, tracing the visible sinews of her muscles starting from her elbow to her wrist, and finally found himself face to face with her open palms, holding a brown, nondescript leather wallet. He wondered what that was all about until he finally realized that that was his wallet. He quickly turned and dug around his bag to confirm, and indeed, his wallet was not in its proper place in his bag.

"It's yours." Sakura confirmed, seeing his bewildered look. "I saw him take it from your bag."

"Oh." Kakashi replied, as he retrieved his wallet back from her, "thank you for taking care of it, then. I knew that kid wasn't from around here."

He saw the corners of her lips turn upwards as she tried to fight a smile. "Our school really should step up the security. How did you know he wasn't from this school, Kakashi-sensei?"

Kakashi felt an unmistakeable thrill down his spine at the fact that she still remembers him. It was just one semester after all, and he really wasn't the interactive teaching type. "Konoha's a small university." Kakashi replied with an easy grin. "I know everybody."

A cat-like smile spread across Sakura's face, her previous shyness all but forgotten. "Really?" She asked, "then do you know me, sensei?" Her voice had changed from the demure one she was using earlier to something close to a seductive purr. Kakashi didn't know what to make of it.

"How could I ever forget the most brilliant student during my first year of teaching? How are you, Sakura-chan?" He said, using the nickname he heard her friends use often. Her grin turned wider.

"I'm great. I'm glad you haven't forgotten me, sensei."

"Like I said, I can't forget you." Kakashi said, as he watched her expression turn more pleased.

"I can't forget you too." She said in a whisper that Kakashi barely caught.

"What?" He said, can't believing what he just heard.

"I said, would you like to get coffee with me sometime?" She replied.

Oh. Coffee. He did mishear after all. She was just inviting him for coffee, wait, what? "Sakura-chan," Kakashi said carefully, "do you know what you're asking?"

Sakura nodded, "yes. I'm asking you for coffee. And then maybe we can reserve dinner for a second date."

Sakura's grin was tempting, and perhaps this was the reason why Eve fell for the forbidden fruit. How can one resist when the forbidden fruit, who looked so delicious, so mouth-watering, was offering herself up to you? Kakashi tried to shake of these thoughts and cleared his throat, "I don't think that would be acceptable, Sakura-chan."

She frowned. "Why not?"

Isn't it obvious? "I'm a professor in this school. You're a student. Even though I'm no longer teaching you, it still isn't right."

He thought this would discourage her and finally end this conversation. However, he saw her face collapse in relief. "Oh! I was scared you'd say I'm not your type or something." She said, her face splitting into an open grin.

Ha. As if any man in their right mind would refuse somebody as perfect as Haruno Sakura, class valedictorian and this school's star athlete. Not to mention eyes that are green as the leaves on the trees on a fine spring morning and lips that looked so soft, Kakashi would probably melt into them if he tried to kiss her. "If that's all," he heard her say, "then you totally wouldn't mind dating me if I'm no longer a student of this school?"

"I – guess?" Kakashi said carefully. He felt like she was leading him into a trap.

"It's a good thing I'm graduating this term, then." She looked like the cat who got the cream. "See you in a few weeks, Kakashi. Call me."

He watched her as she walked away from him, mesmerized at the sway of her hips. Slowly, he looked down at the wallet that turned this day from drab to what felt like the beginning of a new era. He saw a piece of paper sticking out from one of the folds and pulled. Scribbled onto a piece of stationery was Sakura's name and cellphone number. Kakashi smiled and folded the paper carefully, tucking it back inside his wallet for safekeeping. The end of term is in less than a month and he had a coffee date to plan.

The tumblr post was: "Someone took my wallet from my bag, and I didn't realize it until you start running after them and tackled them to the ground. You then proceed to hand it back to me and, oh wow you're really hot when you're out of breath." AU and I had to write something and of course it had to be KakaSaku
