This is absolutely OOC because somehow, I see Kagura becoming all girly and tsundere-like when she grows up and when it comes to boys.

This didn't come from a prompt, btw :

Kagura was getting dizzy with all the reviewers that screamed different types of formulas in her face.

She couldn't understand Mechanical Physics wherein she had to memorize and analyze A TON of equations. It was all basic, really, but she couldn't help but question the significance of these figures and how it would affect her career as a future business woman. She wouldn't really need to know how fast a car was moving or the amount of torque present if said car was driving on an inclined plane when she would graduate. Really, what was the purpose?

"Why are these formulas the same? How did I end up getting this?" she chanted more questions to herself. Ultimately, they remained unanswered questions. She was so engrossed in figuring it out that she hadn't realized that someone was awfully close to her.

"China…" the voice whispered into her ear. She paid it no attention. But the owner of the voice soon snaked his arms around her waist and brushed their lips on her neck. "Maybe you should take a break? You can do that later." He said, against her skin. As a result, she shakily let go of her pen and turned her head to the clinger

"Stop it, you Sadist! I'm trying to concentrate here." She hissed accompanied with a deadly glare. "It's easy for you, you're the one who teaches the course!"

Okita clicked his tongue. Technically, he didn't teach the course to their class. He just came in as a substitute teacher for the sophomores and would just manage the students and check their papers. But that didn't mean he didn't know the subject. He was smart, a genius even, and had graduated early from college and was now taking up jobs for experience when he found out that his childhood friend would be one of the students he would manage.

It wasn't long before some kind of tension developed between them. To be fair, the tension was already there from the years before, it just hadn't manifested yet. At first they really thought they hated each other and thus resulted to fighting and name-calling. But, that didn't stop them from harboring some romantic feeling towards the other. By the time they knew it wasn't hate, they were already secretly making out in a lecture room during one of their coinciding breaks.

"Come on," he pleaded. "Just take a break. You can do that later!" Kagura frowned and he took the opportunity by capturing her lips with his. He could vaguely taste the flavor of sukonbu in her mouth and reminded himself to convince her to switch to another type of snack. Kagura wasn't protesting and proceeded to lock her arms around his neck, deepening their kiss.

He lowered his hand to roam the soft skin of her legs until it crept up to the hem of her skirt. He was slowly lifting it when Kagura suddenly broke the kiss, staring at him as though she saw a ghost.

"MOMENTUM AND FORCE!" she shouted.

Kagura pushed her lover aside, not really caring whether it was the floor he was now kissing, and proceeded to scribble down sets of formulas. She was absolutely focused that someone would think she might actually punch a hole through the table just by writing. Within a few more minutes, she raised her paper and announced that she was done.

"Oh, is that right?" Okita grimly said.

He pressed his knuckles on either side of her head and started turning his fists. Kagura let out a sharp cry before trying to pry off his hands from her temple.

"You sadist! What was that for?" she rubbed her aching head. She was almost sure that whatever she had studied were squeezed out when he did that.

Okita was about to start arguing when he decided that it would be best to stay calm. They were in his apartment and his neighbors might not think highly of him anymore if they heard them. If they found out that he was dating one of his students (albeit just his temporary student), gossip would spread like wildfire and his chances at working at a bigger place would become slim, all because he couldn't keep it in his pants.

He let out a sigh. "You were supposed to take a break with me, weren't you?" Okita tried to keep his cool. He couldn't help but long for her when her attention had been glued to her books and reviewers for weeks, preparing for her midterms. Even the most obvious show of affectionate didn't seem to get to her, and he wasn't a very affectionate man. He rested his elbow on the low table and dropped his forehead on his palm. "Couldn't you just give me a bit of attention? You've been at it for weeks!"

Kagura organizes the papers scattered, "That's easy for you to say, I'm the one who's going to take the exam, not you." She gets an annoyed and then defeated expression from him. She felt a bit sorry for him, really. She had been ignoring him in favor of studying for a while. But she had to! If she didn't give her best, even with the minor courses, she'd have a hard time in graduating. She sighs. "I promise, after the midterms, I'm all yours. We'll do whatever you want."

If Okita was delighted with her offer or annoyed by the fact he had to wait, he didn't show. He took one of her textbooks and flipped through the pages. "Is this what you're studying?" Kagura nods and he grabs the pen from her, doing away with some of the exercises in the book.

"What are you doing?" she scoffs.

He didn't look up, "Obviously, I'm going to tutor you if you're really hell-bent on acing that, might I add, easy test." She pouts but accepts his offer. Who better to tutor her than a "genius" and the substitute teacher?

A week of pulling all-nighters and standing the taste of coffee made Kagura feel so dead inside. All she could really process right now were all the things she had studied from the weeks before. It didn't stop there. She could physically feel the toll of studying and the ache in her back from arching on the desk. So this was the real life of a student.

She comes out of the room, her final test taken, and all she wanted was just to lie down, even on the school floor. She couldn't understand what her best friend, Soyo, was blabbering on about just after the test. Where was her friend's energy coming from?

"And so, I'm really at war with myself whether I should've answered A or B. What did you choose, Kagura?"

"I chose the Charmander…" she drawled, her eyes drooping.

Soyo just giggled and patted her back. She understood just how tired Kagura was and how she deserves a well-earned rest.

"You can't sleep yet, Kagura." She said. "Mr. Okita asked for you to come by the Physics room after your last test. I think it has to do something about your Physics results? I'm not sure."

At the words "Physics results", Kagura eyes snapped open and she could feel the weight of everything become even heavier. Her heart was racing. Did she get a high mark that he simply had to congratulate her? No, it wasn't like that. She must've failed the test, and she knows Okita would be mad at her. Why else would he call for her? He'd be so annoyed and all she'd hear from him was how he wasted his time when she was going to fail anyway.

She composes herself. Better get it over with. She gives her thanks and leave to Soyo and heads for the third floor of the next building.

Kagura took her time in walking. She had to plan how she would explain herself to him.

"I was so distracted by you…" or

"I didn't learn jack-shit from you!"

Either way, he'd still be mad at her. And she actually hates it when he gets mad. She feels all guilty inside and she was very annoyed by it so she refrained from angering him all the time.

Once she arrives at the hallway that had the room, Okita was already waiting outside, sporting his usual deadpan expression. But to Kagura, it seemed as though he was not very happy. He sees her and beckons for her to come inside the room.

This is it. I better kiss my vacation and love life goodbye!

He closes the door behind them and slowly approaches her. With his hand on his chin and his other hand in his pocket, she was sure that she was getting a sermon far worse than what her Papi would tell her.

"Okay, I'm really sorry if I―" she was stopped when he suddenly pulled her face to plant a small kiss on her lips. "―disappointed you?"

He didn't respond and, instead, joined their lips once more. She was really confused at this point but decided to go along with it. Hell, this was better than a sermon. Okita's hands guided her arms to be wrapped around his neck and then had her hook her legs on his waist. He easily carried her towards the rectangular table on the platform, in front of the room, and had her sit on the edge of it.

She felt a bit guilty that she was taking advantage of his thirst for her and spoke up once more when his lips were on her neck.

"I'm really sorry," he sucks on a certain spot. "I should've passed the test." He still doesn't respond and proceeds to unbutton her white blouse, granting him access to more of her skin. "Please, don't be mad at me."

She felt her skin feel a bit cold upon the loss of contact. Okita looks her straight in the eye, annoyed and confused. "What are you talking about?"

Kagura could feel the heat rush to her cheeks. "The test! I know I failed and I know you're disappointed but I was using the fact that you wanted to spend some time…" she blabbered on. The confusion in his face finally left when he rolled his eyes.

"Ah, the test." he deadpanned. His arm reached for the stack of papers behind her, which she hadn't noticed, and held up a test that had her name on it. "See? You got an eighty-percent mark. Still pretty low, if you asked me. It should've been a hundred-percent."

Kagura's blue eyes became like saucers as she took the paper from him. "We did this?" she asked herself. She was so amazed at the mark she got. She was half expecting a failing grade and a fifty-percent at the most. But eighty? Wow, just, wow.

She giggled and gave him a hug by enveloping his neck. "You're pretty useful, after all, huh, Sadist?" She felt so indebted to him at that moment. All his sacrifice and the time he had to endure her endless questioning felt so… loving. Maybe a hug and an insult wasn't enough?

She pulls away a bit, "But, seriously," her cheeks grew hotter. "T-thank you." She locks her lips with his in a passionate and long kiss. She didn't have to give him any long-ass thank you message. This was enough.

He didn't want to break the kiss, but they had to. He keeps his hands on her waist as she marvels, again, at the paper she received from him.

She looked so happy just by looking at what they had accomplished and he felt so contented just by looking at her smile. Yes, he had been waiting for a rather steamier and sexy time with her, but all of those went out the window when she said thank you and gave him a kiss. It wasn't just a kiss. He felt like he was finding out all over again that she had also liked him for a very long time now and that this was their first kiss.

In his mind, he laughs at himself. He sounded like a girl.

He gives her a peck on the forehead and buttons up her blouse. He also fixes her hair, settling it down with his palm, and smoothens the creases on her clothes. "Come on, let's get out of here."

Kagura jumps off the table. "We're not having sex?" she asks, more out of curiosity than disappointment. Okita had to close his eyes, restraining himself from scolding her unfiltered mouth.

"Oh, we're having sex, alright." He smiles at her. "Just not now. And besides, this is a miracle that we need to celebrate." He points at her test paper and proceeds to gather his things.

"Oh, so you're treating me?" excitement laced her voice. "Can other people come, too? Like Gin-chan?"

He felt a vein pop on his temple at the perm head's name. "NO." he simply replied and he chuckles at the way she pouts.

Damn it, China. You've really done some damage on me.

Hihi I kinda liked this one…
