Adding Incomprehension

Summary: It's common knowledge that Sora sucks at math, so his mom tries to help by getting him a home tutor. Well, too bad she hired Riku Hayashi, the most popular and obnoxious guy in school. – AU. RiSo with a side order of AkuRoku. Enjoy.

Disclaimer: Not mine, sadly.

"So, Sora. I understand that you are having… Trouble with math," the stern voice of the principal reached his ears, and the brunette boy sunk in his chair. His blue eyes looked from the older man to his calm, pale math teacher. The principal cleared his throat audibly. "Well?"

"I…" He started, looking at his hands for a second, his fingers playing nervously with each other. "Well. I think I have been improving… Right?" He asked, uncertain. His serious speech sounded foreign to his ears, his tongue itching with the unwonted formality.

The man sighed and opened a file on top of the table, his pale, blond hair partially shadowing his face. He rummaged there for only a second, before retrieving three sheets of paper, mostly covered with red marks.

"As you can see, Sora, here are your marks," he spread the tests before the boy's eyes. The blue eyes scanned the already known marks, the lowest one being the one in the middle – 23% - and the highest one being the one on the right – 31%. "I believe that you know how much effort you will need to be allowed to go to your next grade."

"Uh…" Sora started. Actually, he didn't know. He hadn't even bothered to make the count. He was pretty sure he would get it wrong, anyway, and he already knew it was a pretty high mark.

"I don't know how you can make such mistakes, Sora. Your homework is always almost right," his teacher said, a sigh escaping her pink lips.

That's 'cause I copy it from Kairi. Sora thought bitterly. He lowered his eyes again, not being able to face the disappointment in his teacher's eyes.

"You leave me no choice, Sora, but to contact your parents," the principal started, gathering the tests and putting them once again in the file.

Sora's blue eyes shot up, wide with horror. "No! You can't! They'll kill me!" The principal's eyes narrowed only slightly, and the student swallowed audibly. "I-I mean… There's no need for that, Mr. Ansem. I promise I'll improve."

"Unfortunately, that is not enough, Sora. I will call them before you leave school, and that should leave them enough time to figure out the best solution. I am sure you are a good student, Sora, you just need to focus more."

"B-But…" Sora started, trying to argue. It was an understatement to say that he would be dead if his parents found out. Dead was what his dog was when he peed in the living room. He would have his head cut off and be served as an appetizer for the guests in his parent's anniversary, that's what would happen to him.

Ansem raised his hand, effectively silencing the small boy. "That should be it. You should return to lunch, Sora, otherwise you will not have time to eat."

His shoulders dropped in defeat, and his expression turned into one of total depression. He got up and, when exiting the office, his feet dragged pathetically on the floor. He couldn't believe that his last day alive would be a Monday.

"Sora, there you are! So, how was it?" He looked up slowly at the sound of Kairi's voice, still too caught up in thinking about his last will to actually look happy.

"Man, you look awful. I mean, worse than usual. What happened?" Hayner asked, his chin comfortably resting on Roxas' shoulder. The pale blond roughly shook him off before returning his attention to his book.

"My parents are going to exterminate me! Ansem is going to call them and tell them I'm failing in math unless I turn into a super genius or something!" Sora said dramatically, throwing himself on an empty chair and hitting his face on the table.

"Oh, honey. I hate to tell you this, but I told you," Kairi said sympathetically, patting him on the head. The brunette boy grunted, pressing his face harder against the table.

"Hey, cheer up, Sora. We bought you lunch," Pence said cheerfully, his big, black camera dangling on his neck like a medal.

Sora's eyes instantly peered up, the happy glow slowly coming back to them. He smiled bright when he saw the small mountain of food waiting for him and, without second thoughts, he dug in.

"Told you he'd forget about everything if we bought him food," Hayner said with a grin on his thin lips, casting a side glance at Roxas. "Seems like I know your brother better than you do, Roxy baby."

Roxas only rolled his eyes at that, not even looking up from his book. "You know he will be depressed once again when the food is over."

"Then we'll just buy him more." The dirty-haired blond said with a shrug, and waited two seconds before trying to steal the book from his friend.

"Hey, guys! Look who finally showed up!" Kairi whispered excitedly, pointing her finger at something. No one really looked up, Pence eating a piece of cake while Sora devoured his food like a starving beast, and Roxas and Hayner still on their battle over the book. The only set of eyes that looked up was Olette's, the only female at the table except from Kairi.

"Oh!" The brunette girl covered her mouth with her hands, her eyes shining with excitement. "I thought he wouldn't show up! I mean, he usually never comes on Mondays…" She stated, her voice barely containing her happiness.

"I know, right?" Kairi said, as excited as her friend. They started then a whispering battle, one speaking faster than the other, along with hundreds of other whispers.

"I think this is where we should run." Hayner said, finally giving up on the book, eyeing the two girls with apprehension.

"Nah, they'll go back to normal after a while. Just don't make any sudden movements." Roxas said all too loud, closing his book and setting it on the table.

"Shh!" Kairi and Olette said at the same time, putting their index finger in front of their mouths for effect, and then went back to their whispered conversation.

"I swear I don't know why we are friends with them." Hayner said in a low tone, too afraid to speak up.

"Wach aw chei chalkin' about?" Sora asked, his mouth half full and half chewed food flying over the table.

"Ew, seriously? Gross." Hayner said, backing away from Sora.

"Well, what else could they be talking about?" Roxas said disinterested, indicating a direction with his face. His brother's blue eyes followed that direction, landing on a tall, elegant figure in the center of the cafeteria, seating at the best table available.

It was hard to describe Riku Hayashi, but it was also fairly easy. He had the most beautiful silver hair that ever existed, and even Sora could list at least ten girls that would kill for that hair, and his eyes were of an aquamarine complexion, a rare color for a Japanese person. His pale skin was weird considering the tropical place they lived in, but it suited him inexplicably. His body was muscular without overdoing it, and he could wear nothing but a leopard thong and still look gorgeous. It was easy to understand all those whispers, and why everyone would kill to be in his circle of friends.

Unfortunately for Sora and his friends, they were far away from it.

"Riku sure is cool, though." He said, after swallowing his food.

"You're kidding, right?" Hayner asked, completely perplexed.

"I mean. He is really pretty, and he seems really nice." Sora added timidly, averting his eyes from the beauty in the center of the room.

"He is, isn't he?" Kairi asked, her voice an octave higher than normal, clapping her hands once and keeping them together. "It's like… He is this hot model! Maybe I should get an autograph now before he gets to famous for us to get close to him!"

"Oh God, no. Please don't embarrass us more than you already have." Hayner muttered, not really trying to hide his disgust, just trying to stay low on Olette's radar. Unfortunately for him, he couldn't make it.

"Hayner! Be nice!" The brunette girl warned, a flash momentarily blinding them.

"Sorry. Just thought it would be nice to save a picture of this as one of our high school memories." Pence said, scratching the back of his head with one of his hands.

Olette huffed, trying then to steal the camera from his friend, saying that she must look horrible in the photo. Sora laughed shortly before shooting Riku a quick glance, getting his last sight for the day. It wasn't like he was obsessed with the boy or anything. He didn't even like him. It was just... This harmless jealousy. How Sora wished he was more like Riku, with his perfect grades and perfect life.

When classes were over, Sora wished he could suddenly become a marksman's target, or be hit by a meteor. Anything to stop him from going home. He even tried to beg Kairi and Olette to take him to the mall, but they said it was a girls' afternoon and no boy would interrupt it.

"Can I go with you guys?" Sora asked, pleading eyes staring at equal ones, then chocolate ones, then brown ones.

"Sora, the longer you take to get home, the worse things will get," Roxas warned, crossing his arms in front of his chest.

"There's no way things can get any worse!" The brunette said, pulling desperately at his brown spikes.

"Don't say that, Sora. Maybe your mom isn't as mad as you think," Pence offered, a sympathetic smile on his face.

"Right. I'm just glad I'm not you, Sora," Hayner laughed, waving at Sora before turning on his heels. "Let's go, guys, the movie will start before we get there!"

"Good luck, Sora! Call us if anything happens!" Pence smiled one last time and ran off, joining his two blond friends.

Sora bit his lips and said nothing, waving good-bye to them and going not too willingly to his death sentence.

He entered his house as quickly as possible, tip-toeing to the stairs with the ability one only got when they were in extreme trouble. Unfortunately for him, his mother's abilities to sense him were greater than his abilities to remain unseen.

"Young man, stop right there," her soft yet severe voice called. Sora stopped as if frozen from head to toe, turning back slowly. His eyes rested on his mother, arms crossed over her small chest, apron on and baby blue eyes narrowed dangerously.

His mother was, in simple words, small and delicate. She had the incredible ability of being smaller than her two sons, her straight brown hair resting delicately on her shoulders and giving her sort of a toy appearance. But Sora knew better. Being raised with four older brothers, his mother could be worse than the devil when she wanted. And now was one of those moments.

"H-Hi mom," the son said weakly, swallowing audibly.

"Don't 'hi mom' me," she warned and, unfolding her arms, pointed to the couch, "sit."

Obediently, Sora sat without saying a word, his bag still hanging on his left shoulder, but not heavier than the panic that was consuming him. His life was over, that was certain.

"I got an interesting call from the principal of your school today, Soras" his mother began, standing in front the couch, glaring at him. "He said you are almost failing maths. Almost. Failing." She said, each word separated by a breath, just for dramatic effect. "What do you have to say in your defense?"

"Um…" Sora started, looking at his mother's face, her shoulders, her nose, anywhere but her piercing eyes. They made him feel incredibly guilty. "Math is not my strength?" He offered reluctantly.

"Not your strength?" The mother repeated, clearly exasperated. "Sora, you had more than half a year to work on this, and the only excuse you have is that math is not your strength?"

Sora whimpered, trying to blend with the couch, shrinking more and more as his mother spoke. His eyes were closed, and opened again when she stopped speaking, visibly taking a deep breath and counting to ten. Or maybe twenty. As long as she needed to regain her calm.

"You, young man, are in deep trouble," she started again, her voice low and still dangerous. "No video-games, no TV, no movies, no going out with your friends. You are grounded until you get your grades better, maybe even further than that for not saying anything or asking for help! And God help me, if you fail, I'm sending you to military school!"

Her son remained quiet listening to his death sentence, knowing better than to interrupt his mother or counter her when she was this mad. She was usually a very calm and composed person, except when she got irritated.

"I will also get you a home tutor. The principal has recommended me a few names from your school, I'll contact them and you get you one by tomorrow," and with that, she left the room, going back to the kitchen and leaving no room for argument. "And go to your room study!" She yelled a few seconds later, seeing that her son was still on the couch, looking dejected like a lost puppy.

"So I guess you are screwed?" Hayner asked, picking disinterestedly at his food.

"Hayner! Language!" Olette warned, sending him a dirty look.

"What? It's true, isn't it?" The boy retorted, looking at her for a second before turning his attention back to the brunette boy.

"My life is over," Sora mumbled, looking down.

"No, it's not. You just have to get a really high mark on the final test, and then you'll be happy and ready to move on with your life, right?" Kairi asked, trying to sound positive but no quite reaching there.

"But that's impossible! I tried studying yesterday and it was like I was reading Greek or something! I didn't understand any of it!"

"Well, you have a home tutor going to your house, right? He'll help you!" Pence offered in his usual cheerful tone.

"Or maybe Sora is a lost cause," Hayner said, grinning in his mocking way.

"Hayner!" Olette called his attention again, trying to open a whole in his head with her look.

"Anyway," Roxas cut in, rolling his eyes and putting his book on the table, "you try and focus, Sora. Seriously. Mom is pissed."

"I know! And I don't want to fail!" He said dramatically, covering his face with his hands momentarily. "I don't want to go to a military school! They have dorms there, and I'll be away from home, and get bedtime! Bedtime!"

"You're getting bedtime now, Sora," his brother said, matter-of-factly.

"Ugh! Don't remind me," and the he hit his head on the table, groaning loudly.

"Hey, cheer up, man. Maybe your home tutor will be a hot chick or something!" Hayner said, leaning a little on the table, his grin wider than before.

"Yeah, or maybe she will be a mean bitch that doesn't know how to teach at all." Roxas said, matching grins with Hayner.

"Rox! You're my brother! You're supposed to be helping!" Sora cried out exasperated, his eyes tearful.

"I'm the younger brother. It's my job to ruin your life," the blond brother stated, resting his chin on his hand.

Sora groaned again, clearly defeated, mumbling something that sounded like 'I'm definitely going to military school'.

Sora stood in front of his front door, staring challengingly to the offensive wood, his bag heavy on his shoulders. He had two options.

Option A, he could just go inside, meet his terrifying new tutor, and get it over with. Certainly it would be a traumatic afternoon, but quiet enough, without bigger incidents.

Or option B, he could go inside, throw himself to his mother's feet and beg her to cancel his tutoring sessions, claiming that he would be good and surely get a good enough grade on his own.

Clearly option A was the best; there was no way that he would get a good mark studying by himself. And maybe, just maybe, his tutor wouldn't be so bad. Maybe he could get a new friend. Yep, option A was definitely going to win.

"Are you going to stare at the door all day long or are you actually going to ring the doorbell?" A smooth voice asked from behind him. Sora squealed in a very manly way and turned fast on his heels, his sight going momentarily black from the sudden movement. And when he could see, his baby blue eyes grew wide with shock.

His mouth opened and closed several times, like a fish outside of the water, but no sound would come out. He had never actually imagined that scene, Riku Hayashi right in front of him. Right in front of his house.

One perfect silver eyebrow rose at his odd reaction, and again that smooth voice came, calm and composed.

"Listen, I need to ring the doorbell, so if you don't mind stepping aside." Riku said, a small smile gracing his features, making him look just a little smug, but perfect none the less.

"I… I…" Sora started, his brain suddenly incapable of forming cohesive sentences for his mouth to say, making him look like an idiot. He reached back, his hands groping for the doorknob, finally finding it and turning it rather harshly. Sora pushed the door open and stepped back until he was finally inside his house, his theoretically comfort zone.

"You live here?" Riku asked, seeming quite perplexed.

"I…" Sora repeated, feeling pathetic. It was just a simple yes or no question. It couldn't be possible that he couldn't answer that. "Y-Yeah. I live here." He finally said, his voice sounding a bit hoarse. The brunette swallowed audibly, trying to get more comfortable.

"Okay." The silverette said slowly, eyebrow still arched, maybe doubting the smaller boy. "I'm here to tutor Sora Kayaki, his mother hired me."

Sora's heart skipped a bit. Oh God, was Riku going to be his home tutor?

"Sora! What are you doing there at the front door?" His mother's voice resounded through his ears, suddenly bringing him back to reality. "Close the door, Sora!" Her voice sounded much closer now, along with her steps, which suddenly stopped. "Oh my. Are you a friend of Sora?"

"I assume you are Sora's mother?" Riku asked, his voice all polite. "We spoke on the phone. I'm Riku Hayashi, I'm here to be Sora's home tutor."

"Oh, that's right! I didn't expect you to arrive this soon. Please, come in!" She said, her voice delicate and soft. Sora, however, didn't move out of the way to let the older boy come through. "Sora, honey, step aside." His mother asked, her voice just a little less calm.

Sora did as he was told in an automatic manner, not really realizing what was going on, still stuck on the fact that Riku Hayashi was going to be his home tutor!

"I hope you can help Sora, you see, he needs a lot of help. I do hope you can still remember what you learned, since you are a year older than him…" The women started, talking in a rushed way. "But the principal did give me your contact number, so I'm hoping this will be alright? You boys can study up there in his room, it's a lot calmer there. I'll go up in a while to bring you guys some snacks." She finished then, looking at Sora who was still in automatic pilot. "Sora, honey, go study in your room." His mother said, voice rougher than before.

The brunette boy blinked once before finally going back to his senses. "Right! Study! Um…" He looked at his Riku, their eyes meeting momentarily, then back to his own feet. "T-This way." He said weakly, balancing his bag on his left shoulder and going to the stairs, climbing it slowly with Riku's silent steps following close behind, not saying a word.

They entered the smaller boy's bedroom, surprisingly neat since his mother made him clean it the day before due to his tutoring sessions. He put his bag on the bed, then slowly turned to look at Riku standing in the doorway.

"You can… Um… Put your bag in the bed. I'll go get you a chair." He said, not waiting for an answer to pass the older boy and go to his brother's bedroom, getting his chair and pushing it all the way to his bedroom, finding Riku still standing but with bag on the bed. "You can sit here." Sora mentioned to the chair and went over to his bag, picking up his notebook and pencil case, noticing that Riku was silently doing the same, his face expressionless.

They sat on the chairs in front of the desk and, suddenly, Riku put Sora's tests on the wooden surface.

"Ansem gave me a copy of your tests so that I could see what you have trouble with." The silverette suddenly started, not quite looking Sora in the eyes. "You suck at math, you know that?"

"I…" Sora didn't know what to say. Okay, sure, he was bad at math, but he didn't need someone telling him that, being it Riku or not!

"You can't even get multiplication right. The only questions you got right were out of luck. I'm surprised you even got your name right." Riku continued, clearly ignoring the younger boy, still not looking him in the eyes.

"H-Hey!" Sora protested, blushing in embarrassment and anger. "You don't have to be rude!"

"Now you listen to me." Riku said suddenly, pointing his index finger at Sora's chest but far away from touching it. "The only reason why I'm doing this is because my parents and Ansem asked me to. I'm not doing this for you." He said with some disgust before continuing. "I have a reputation to keep, so I'll tell you only once: you better get a good mark on the final test or I'll castrate you with my own hands. Is that clear?" He said in a threatening way, with his tone low and beautiful eyes narrowed.

Sora didn't answer, of course. He was too shocked for that. Where was that cool guy he saw at lunch, who smiled to everyone and chatted and looked so kind? The one who had the best reputation at school and people would die for to get close to him? Did Riku have an evil twin brother?

"Is. That. Clear?" Riku asked again after what was like five seconds of non-response.

The younger boy swallowed and gave a shake nod, too afraid and shocked to talk.

"Good." And then Riku leaned back on the chair, just the exact moment his mother came through the door, snacks and glasses in one hand and cranberry juice in the other.

"Here it is boys. If you need anything, Riku, just ask, okay?"

"Sure, Mrs. Kayaki. Thank you for having me here." He replied in a gentle voice, getting up and helping Sora's mom put the things on the desk, looking completely different from before, leaving Sora dizzy and confused. Maybe Riku was bipolar?

When his mother left, Riku stared at him again with those cold eyes, making a shiver run down his spine.

Sora was beginning to think that option B was better.

So here it is. My first RikuSora. No beta, probably lots of mistakes. I hope you guys like it.

The title is from Brazilian writer Clarice Lispector's story, Forgiving God. It's a quote that goes like this:

"Because I made from love a wrong mathematic calculation: I thought that, by adding the comprehension, I loved. I didn't know that, by adding the incomprehension is that you truly love. Because I, only by having affection, thought that it was easy to love."

Read and please review. Critics or just a "it's good!" would be totally awesome.

Thanks!

Beijos, Clem.
