A/N: Hello everyone! I'm so glad I finally came up with something to write about with Bon and Rin because they are a pairing I love so soo much. I'd been thinking and thinking forever and thought up this story. I'll be honest, I don't know how long it's going to be, but I guess we'll find that out together! xD

I'm giving it a T rating for now, but if you're familiar with my work, it will eventually change to M.

Please read and submit a review, lovely readers!

All the Right Reasons in this Beautiful Season

Arguments and Invitations

To say Rin Okumura was 'out of it' would have been an understatement.

While sitting in class listening to Yukio, his younger twin brother, lecture about the history of the Kraken, he had to keep himself from falling asleep. It didn't help that it was after two o'clock, meaning it was almost time for class to end. Plus it was Friday. If he didn't live with his teacher, he would have considered skipping out on class today.

Looking out the classroom window to the blue, cloud-filled sky, he smiled. It was almost the end of the academic year, and that meant summer vacation was on its way.

Grinning eagerly, he began thinking up a list of things he planned to do while school was out.

Like going to the beach, surfing, exploring, having tons of fun, and maybe going on a date… if that came up.

Subtly turning to his right, he observed Shiemi Moriyama, a pretty and very youthful blonde girl who happened to be one of the first people he met at this academy, as she rushed to take as many notes as possible. Her devotion to this even though her grades weren't necessarily the best was something Rin admired about her. They often failed a test or two together, but somehow managed to make up for that with homework assignments and an occasional passing test grade.

Dating Shiemi had been on his mind ever since he saw her in her garden, and that desire grew even stronger when she came out of her shell more and started wearing an actual uniform… which showed off her attractive figure, proving she wasn't just a little kid. That innocent face of hers made it hard to imagine doing anything… naughty with her, though. So Rin eventually put the idea of dating Shiemi on the back burner, and he made sure the heat was off.

When she turned and looked at him with her emerald green eyes, he jumped.

"Rin? Are you okay?" the girl asked with a smile.

Jeez, she really was innocent…

"I'm fine. Thanks for asking. I guess… I'm just a bit tired." Rin whispered back, making sure to carry on a dialogue with her while Yukio wasn't looking.

"Hm. Okay. You should get more sleep at night, that way you'll feel much more energized in class."

"Right."

Rin's deep blue eyes wandered past Shiemi to the dark-haired girl who was seated off by herself.

Izumo Kamiki.

She was a year older than he was, and had a wavering chip on her shoulder for other people to boot. Often times, she was the first to arrive in class and tried her best to be the first to leave. That kind of anti-social attitude was both repelling and inviting. Nobody wants to date the person who is always busy or always with someone, but still, she could make more of an effort to get closer with everyone. They'd all been through so much together.

"Why am I thinking about dating polka-brows?" the pointy-eared boy thought.

Moving on from her datability, Rin honestly started to wonder what she would be doing this summer. She didn't usually talk about her home, or family for that matter. In fact, she remained distant from everyone in those respects.

At hearing a laugh coming from the back of the classroom, the boy turned and looked over his shoulder at the three only other guys in the classroom… apart from the puppet-holding guy, Nemu Takara.

Renzō Shima, Konekomaru Miwa, and Ryūji Suguro.

The three of them were a trio that was seldom seen separated. They had a close friendship, and Rin was a little jealous that he didn't really have that. Only the tiniest bit, though.

Each one of them had very different personalities, which had been a little strange to him at first. It wasn't until their trip to Kyoto that he learned the three of them practically grew up together. He knew from then they would always be close, no matter what.

The laugh he'd heard came from Shima, of course. Shima was always laughing about something, and it occasionally got him into trouble.

"It's not funny…" Suguro said with his eyes closed.

"Sorry, sorry." Shima apologized, and then crumpled up a piece of paper.

"Is there something we should know about?" Yukio asked, now looking at the trio.

"Absolutely not, sir!" Shima answered seriously.

Konekomaru seemed like the only one of them being attentive and respectful.

Rin raised an eyebrow when he saw the glasses-wearing boy trying to hide a smile.

So he was in on whatever joke Shima made, too, huh?

"Well anyway…" Yukio said, and then looked down to the watch on his wrist. "I guess that's it for today." He continued. And immediately after he said that, the bell rang, signaling the end of class for the day.

"Yes!" Rin shouted excitedly.

The weekend had officially begun.

After packing his briefcase and heading over to the classroom door, Yukio turned. "Please don't forget about the final next week, you all. Study hard so you can do well!" he said, then turned and exited the classroom.

"F-final?!" Rin echoed.

Shiemi looked at him curiously. "Did you forget, Rin?"

"I… I don't even remember hearing about it!"

"Of course we're having a final, silly. I've been studying for it already… There's so much material to cover." The blonde girl continued, looking down to her notes.

"Well, I'm not gonna let some test bum me out! Summer's almost here, so I'm definitely gonna live it up as best I can!" Rin said with a grin. "Oi, Shiemi? What are you gonna do this summer?" he asked, seemingly putting the exam out of his mind that easily.

"Me? Well, I'll probably end up working at the shop with my mom."

"Hmm? Sounds totally boring."

"It's okay. I'm fine with it. And what about you?"

"I… uh… I don't know just yet." The navy-haired boy answered sincerely.

Having overheard the conversation between Rin and Shiemi, Shima walked up with his booksack on his back. "What are you knocking her plans for when you don't even know what you'll be doing?" he asked.

"Hey, I didn't tell her to jump off a bridge or anything! I just said it sounded a little boring."

"You shouldn't give Moriyama hell for having plans if you don't even know what you're gonna do." Suguro said, coming up next to Shima with his bag over his shoulder to look down at Rin.

"Can we drop it, guys? It wasn't that big a deal." Rin turned from Shima and Suguro and looked at Shiemi. "I'm sorry for calling you plans boring, Shiemi."

"It's fine! I know working all the time isn't the most interesting thing to do."

Rin quickly turned back to Shima and Suguro. "There, we made up. It was honestly none of you guys' business to begin with though…"

"That's not the point, baka!" Suguro shouted.

Konekomaru quickly came over and put a hand on Suguro's shoulder. "Bon… Please, come on. You shouldn't be arguing with Okumura."

"Yeah, he's not worth the time or the headache…" the Mohawk-haired man said, and then continued on his way out of the classroom.

"Putting that behind us," Shima began with a smile, "See you guys next week!" he said. When he saw Izumo heading to the door, he hurried over to her side. "Izumo-chan! Do you need someone to walk you to your dorm?!"

"No. Jeez. You sure are a persistent fellow." The dark-haired girl said, and then left the room.

"Izumo-chaaaaan… You're so cooold." Shima's voice echoed in the hallway.

After retrieving his bag from his table, Konekomaru made to follow after Shima. He stopped however, when he got in front of Rin and Shiemi's table. "Sorry about Bon. I know we're all friends and all, but it seems like you two still can't go too long without arguing. Don't read too much into it, though. He means well." He said to Rin, and then left the classroom.

Shiemi turned. "Rin…"

Said boy picked up his booksack and got up. "Shiemi, do you need me to walk you back to your place?" he asked.

"Huh? Oh! No! I'll be fine on my own!" the blonde replied.

"You sure?"

"Yup! I've always got Nii-chan with me if something bad happens! You should go home and study! Don't worry about me!"

Rin smiled down at Shiemi and nodded. "Okay. I'll see you later, then." He said, and then left the classroom.

He was pretty glad it was the weekend. Now he could finally relax.

"Oi, Rin. Shouldn't you be studying for the final exam next week?" Yukio asked, looking up from his paperwork to his lazing brother.

"I'm going to. I promise." Rin responded, lying on his bed with his hands behind his head nonchalantly.

"This is no joke, Rin. I'd like for you to pass the exam, so you'd best be doing all you can to prepare."

"You could give me the answers. That'd help a lot, haha. ...Though even if you did, somehow I doubt I'd get anything higher than a 'C'." Rin said.

"Rin, I mean it-"

"Okay, okay I'm doing it."

Rin sat up and got off his bed, then opened his booksack that he had left on the floor when he'd first gotten back to the room. After pulling out his notebook, he stood up and walked to the door.

"Where are you going?" Yukio asked.

"To study on the roof. I can't be cooped up in here while reading or I'll end up falling asleep."

There was some truth in that statement, but honestly he really didn't want to feel pressured by Yukio's presence.

"Okay, but don't slack off. It's a cumulative exam, you know?"

"Yeah, yeah."

While walking through the dormitory, Rin couldn't help but wonder if he would just end up spending his entire summer here doing absolutely nothing.

Right before he reached the stairs, Kuro, his familiar, seemingly came out of nowhere and started rubbing up against his leg.

"Kuro? What's wrong? You hungry?" he asked, kind of hoping he could start cooking. Perfect excuse to not have to study.

"No, I want to play! Let's go outside, Rin!" the cat replied eagerly.

"I'd love to, but I have to study. Mole-face won't stop bugging me about it. We can play together later on though, okay?" the boy said, waving his notebook in the air.

"Okay! Guess I'll go play by myself for now!" Kuro said, and then headed to the front door.

"Have fun, Kuro." Rin said. He then turned and climbed the stairs. Reaching the door that led out to the roof of the building, he unlocked it with his key and put his hand on the door handle. After opening it, he stepped out into the fresh air and inhaled deeply. Thankfully, it wasn't very hot out. There were a lot of white, harmless clouds out today, after all.

"Guess I'd better get this show on the road." He said while walking over to a corner of the roof. Getting down onto his stomach, he opened his notebook and sighed deeply.

It was a daunting task, reading over his scribbled notes, but he would try anyway.

…

Catching himself from falling forward onto his notebook, Rin shook his head and then slapped his cheeks with his hands. "Man, this is sooo boring… I'm fallin' asleep and I've barely even started studying." He said.

Flipping through the dozens and dozens of pages covered in ink in his notebook, he couldn't help but become a little nervous. Yukio mentioned something about it being cumulative, which was always encouraging…

"I'd be lucky to get even a handful of questions right." He lamented.

After a while, the boy realized he was just blankly staring at his notebook. He yawned and decided he should stop for the day. It would do him no good to just keep overwhelming himself like this, anyway.

It was when he got up and stretched that he heard voices off in the distance.

Walking over to the edge of the roof, he was surprised to see Shima and Konekomaru coming towards his and Yukio's dorm. They were talking about something, but he couldn't tell what it was.

After sticking his pointed ears out, he could make out what they were saying.

He raised an eyebrow when he heard them debating about whether or not inviting him and Yukio to study would be a good idea.

"But why Yukio? He's the teacher. Meaning he doesn't have to take the exam." Shima commented.

"Still, he could help us. He's a wealth of knowledge, so not inviting him would be a bad idea. Besides, things might go better if the two of them showed up together, and not just Okumura. This was your idea, Shima. So at least think about ways to go about it that will make it easier on everyone... especially Bon." Konekomaru answered.

"...I guess you've got a point there. Maybe he'll give us some answers, heh."

With a smile, Rin quickly hurried over to the door that led inside. He slid down the rails along the stairs, excited over the thought of hanging out with people. Not to mention getting to study when things weren't so boring.

Even though he'd made it to the front door quickly, the doorbell didn't ring.

Putting his ear to the door, Rin couldn't believe it when he heard Shima and Konekomaru still debating about whether they should do it or not.

Then things grew quiet.

Suddenly, the doorbell rang out from the hallway, and the boy smiled, showing off his straight rows of teeth. They had obviously decided to go through with it.

Rin took a second to calm himself down a bit, then opened the front door.

"O-Okumura…" Konekomaru muttered.

"Huh?"

"That was… kinda fast." Shima said with an amused look on his face.

"Oh, well I was on my way out to play with Kuro. He's been outside for about an hour playing by himself, and I was getting kind of tired of studying." Rin said.

"Kuro?" Konekomaru echoed. "I want to play with-"

Shima cleared his throat and looked at his shorter companion. "Remember why we came here, Koneko."

"Oh, right."

"We came here to invite you and Okumura-san to a study group tomorrow. Wanna come?" Shima asked.

Rin's blue eyes gleamed for a second, and his tail started wagging from his excitement. "Sure!" he replied.

"Cool, cool. Meet us at the library tomorrow around noon. We'll be on the second floor, kay?"

"Okay!"

"Can you ask your brother if he will come too?" Konekomaru added.

"Sure! I'll definitely get him to come. But he has a lot of paperwork to do, so I doubt he can stay for too long. And... thanks for inviting us, guys."

Raising his hands, Konekomaru smiled. "No, thank you. You guys are helping us, too. If we can get Okumura-san for even just a while, that'll be great."

"Well, I'll see you guys tomorrow then!" Rin said with a smile.

Shima turned and waved his hand. "Alright. See you then." He said.

"Take care, Okumura."

"You guys, too."

As Shima and Konekomaru left the dorm, Shima looked up to the sky. "Hm, looks like some storm clouds are coming…"

"Hey, Shima." The shorter boy called quietly.

"Hm?"

"Are you sure this is okay… I mean… inviting Okumura and all… Bon might not be in a mood to study with him."

"It'll be fine! What Bon doesn't know won't hurt him. Besides, it's not like he'll be the only other person there. We managed to get the girls to come too."

"I'm still not so sure…"

"Like I said, it'll be fine. Now let's hurry and get back to our dorm before we get caught in the rain. Those storm clouds are practically coming out of nowhere." The pink-haired boy said, before he started fast-walking.

"O-okay! I'm coming!" Konekomaru said, and then hurried after his friend.
