Desperate people that don't want to study do desperate things... like writing a drabble when they are supposed to be studying.
This one actually my own idea (yay for that!). No beta.
Song of the drabble: Up In Flames by Icon For Hire

Marco grit his teeth as he wrote an equation on the whiteboard. The whole class diligently wrote it down after him except for one person, Portgas D Ace, who had the guts to sleep in his class. Marco wasn't a monster, he knew that the students had other problems besides his math and he looked the other way when students from time to time brought other subjects to his class. However one certain individual thought that Marco's lessons were a wonderful place for a nap. He would have ignored it if it happened once or twice but not every single bloody lesson! Today was the last drop into Marco's already full cup of patience.

"Mr. Portgas, would you be so kind as to get over here and solve this?" the blond said in a strict voice.

He rarely used that voice in class, reserving it only for times when he was really pissed. The students knew that already so the whispered conversations throughout the classroom stopped abruptly. Everyone looked at the person dumb enough to piss Marco off. After a couple of months with their new math teacher they quickly learned that making Marco angry was not an option.

Portgas D Ace remained blissfully oblivious as he continued sleeping without any indication that he heard what the teacher said. A blond friend of the annoying student roughly shoved his friend to wake him up.

"Wha...? Is it over?" the sleepy student said with a yawn.

Marco's eyebrow twitched in anger making the students in the front row shrink in their seats.

"Mr. Portgas, would you be so kind as to get over here and solve this?" the teacher repeated in a voice that left no room for argument.

"Why me?" the idiot student said defiantly.

"Now."

Marco didn't raise his voice but even the worst troublemakers in this class stopped grinning, knowing that their teacher was one step away from unleashing nine plagues of Egypt on the entire class. Portgas' blond friend shoved his stupid and (depending on whether or not he'll piss off Marco even more) maybe former best friend out of his seat. The newly awoken maybe former best friend glared at his also maybe former best friend, but moved to the whiteboard where Marco handed him a marker.

"What am I supposed to do with this?" the annoying student pointed at the equation with the marker.

"Simplify it," Marco went to the teacher's desk and sat in his chair. "The rest of the class please do it quietly in your notebooks."

Students quickly started scribbling in their notebooks. Portgas D Ace was staring at the whiteboard as if he saw it for the first time in his entire life. Marco stared at it as well. The equation wasn't very simple if you slept through the time when he explained a similar one.

"Is this your last class for today?" Marco asked his students who nodded enthusiastically. "When you're done with this equation, do the homework you got at the beginning of this class and bring me your notebook for checking. If everything is right – you are free to go."

His students nodded even more enthusiastically – everyone wanted to finish early on a Friday. Portgas kept staring at the whiteboard, frowning thoughtfully. He started writing something, erased it and started again. So far he was on the right track, maybe Marco was wrong about him.

(^_^)

Ace stared at the monster on the whiteboard – he had no idea what to do with that stupid equation. What the hell got into Marco today? After some more thinking and staring, Ace saw one thing he could do with the equation. What he wrote down seemed legit so he tried to see what to do next. It wasn't going too well – he didn't have a slightest idea.

Meanwhile other students started coming up to Marco to get their homework checked. The teacher quickly scanned it with his eyes and quickly signed it with a red pen, allowing Sabo (treacherous bastard!) to finish early. Ace doubted that he would be leaving the school before he solved the stupid thing. One by one his classmates were leaving; some had to go back to their places to redo something, others got the green light on the first try. And then there was he, feeling like a complete idiot.

Finally the bell rang so Ace moved away from the whiteboard.

"Where are you going, Mr. Portgas?" said the teacher that in half an hour went from being Ace's favourite to the worst teacher ever.

"The bell..."

"You are not going anywhere until you solve that equation," Marco said sweetly with a happy smile on his face.

"But..."

"No buts, less talking more solving," the teacher said cheerfully; Ace have never seen his teacher so happy – he looked like a cat that ate a whole bucket of cream.

"You can't be serious!"

"Now, now, I can be whatever I want to be. You, on the other hand, are not leaving the school until you are done. I'm not in a hurry, I can stay here all night and a whole weekend, but you, I assume, don't want that. So, less talking more solving," Marco looked so smug Ace wanted to punch him in the face.

With a growl under his breath Ace returned to the dumb equation. After two hours of writing and erasing stuff, he turned to his teacher who was comfortably reading a book with his feet on the teacher's desk.

"I don't know how to solve this," he admitted begrudgingly.

"Pity," Marco said without lifting his eyes from the book. "I guess we'll be staying here for the weekend."

"You don't have the right to keep me here!"

"Your guardian already allowed me to keep you here as long as necessary. Less talking, more solving – you were on the right track before you erased it," the sadistic teacher turned a page in his book; Ace grimaced at the mention of Garp – he had no doubts that the old man gave Marco permission to do whatever he wanted to Ace.

"Can I at least go to the bathroom?"

"Of course, just leave your phone here," Marco still haven't looked up from his book.

"It's in my bag," Ace lied.

"Don't make me get up and take it from you by force," the blond put out his hand palm up, waiting for Ace to give him his phone. "Thank you, you can go to the bathroom now," he said when Ace forcefully put his phone in his hand.

Ace stormed off to the bathroom cursing and swearing at the teacher he used to like. Who knew that jerk was so sadistic?! When he unwillingly returned to the classroom, the Sadist just finished talking on the phone to someone.

"I ordered us some take-out since it looks like we'll be camping here for a long time."

"Can't you just give me a hint or something?" Ace said angrily, ignoring his growling stomach.

"Oh, I gave you a hint. I solved an equation just like this one on the board in front of entire class. Too bad you weren't paying attention," the Jerk returned to his book. "If you're not done with this by eight I'll have to make a call to get a couple of sleeping bags here."

"You can't be serious!"

"Less talking more solving."

"I don't know how, okay?! Happy now?!" Ace yelled.

"I'll be happy when you will solve it, less talking more solving," Bastard waved his hand dismissingly at Ace.

"I don't know how!"

"And that is my fault because?" the Sadist finally looked up at his student.

"What the hell got into you today?"

"I'd watch your tongue if I were you," his teacher said calmly, returning to reading. "I could give you a couple more equations."

"Is that the worst you've got?" Ace sneered, thoroughly pissed off.

"Or I can make sure your body is never found, your pick," Marco smiled pleasantly at Ace making the latter wish he never opened his mouth. Or better yet – paid attention in class because somehow he believed without a doubt that he'll never be found. "Now, less talking more what?" the Psychopath looked at Ace to finish the sentence.

"Solving..." Ace sighed, returning to staring at the board.

For those interested I actually have an equation taken from a website of my previous math teacher:
(9x^3 - 16x)/(9x^2 - 24x + 16)
I was actually planning on putting it somewhere in the drabble XD
Thanks for reading :D
