Author's Note:The second part of the story! We still have a ways to go though~ By the way, I should probably have mentioned this in the first part, but I made the Reader and Koganegawa are senpai and kouhai because of a wonderful drawing by the wonderful shoucheeky (on tumblr), who very kindly also let me write a drabble to accompany that awesome picture! Please check it out! I hope you enjoy~

You flip through the papers in your hand, going over them forthe third time. You're watchful eyes pass over every inch of them, each a test or assignment that Koganegawa had been graded on. Since school has barely started the stack in your hands is relatively light, but they're very useful in showing you where Koganegawa's problems lie.

The first thing you notice is that Koganegawa is actually quite sharp, and he understands the material pretty well. The answers he puts down are pretty detailed and have a fair amount of thought put into them. The problem is the vast majority of the time that he writes those good answers, they're in response to a question complete different from the one actually being asked.

It had quickly become apparent that Koganegawa rushed through everything, often times not reading the question completely and either putting in an answer that is half right (or only answers half of the question) or starts writing about a subject completely different from the one being asked about. That's not to mention that his writing is hurried and sloppy, and had he lost many marks just from what he was writing being completely illegible.

There are a few subjects that he's obviously misunderstanding, as well as some questions he clearly can't remember what the answer is or how to arrive at it. Still, he tries his best on every question, even ones where he clearly has no idea what to put. His determination and refusal to give up impresses you, and gives you very high hopes for his future grades.

You finally look up to see Koganegawa anxiously squirming in his seat. He'd become…relatively calm, at least compared to when he first arrived.

The moment he'd stepped into your house, less than an hour ago now, he'd practically been bouncing with excitement and seemed to have no control over the volume of his voice. You'd heard so many shouts of "Senpai!", among a long string of non-stop questions about your home and family, that you had to sit him down and gently (but firmly) tell him he needed to calm himself if you were going to get anything done. He'd agreed, nodding his head enthusiastically as you could see how determined he was to stay quiet.

He really did try his best at everything.

It had obviously unnerved him when he entered your room though. He'd stood in the hallway just outside your bedroom door for a full minute after you entered, blushing bright red as he stared into your room. You'd looked around, wondering if you'd missed cleaning up something and had a stray piece of underwear around, but there was nothing like that to be seen.

It was then that he suddenly piped up that he'd never been in a girl's room before, at least not one that belonged to someone outside of his family. You couldn't help but laugh, although you'd quickly covered it up, as you grabbed his arm and gently (but once again, firmly) pulled his large body into your room. He'd stumbled as he stepped in, clearly still nervous. You'd led him over to a table low to the ground, with some soft pillows as seats. You'd sat down across from him, setting out all the supplies, as he looked around anxiously. You wish you could have said something that might have calmed him down, but you needed some quiet time to go through his tests anyways, so letting him stare wide-eyed and silent at a bottle of body lotion on your dresser (even though his face was so red you could practically feel the heat emanating from your seat across from him) seemed to be a fair choice.

Now, you put the papers in your hand down and pick up a few pages from the large pile of notes Koganegawa had given you. Just glancing quickly, you can see that he writes good notes and pays attention…some of the time. There are some large gaps in material, and they also coincide with Koganegawa writing down what you can only assume are volleyball attack names ('two attack' was a particular favourite of his) and ideas for cool new moves he could try.

Still, 'pay more attention in class' is a lot easier to help him with than 'actually start paying attention in class instead of imagining what bra the girl in front of you is wearing', an issue your friend had with her also a first year brother.

"Okay!" You say loudly, and Koganegawa jumps in his seat.

"SHOWER!" He yells out loud in response. You're both silent for a few moments as you try to understand what he means. Meanwhile, Koganegawa looks horrified, his hands balled into tight fists and pressed strongly against his thighs.

"Um…maybe wait until you go home, Koganegawa-kun?" You say gently. "After all, we still have some work to do…"

"N—No, I didn't mean—! I—I…er…" Koganegawa stammers as his face turns even redder than before, and he hunches down in his seat like he wants the ground to swallow him up. You feel a bit bad for him (it's not easy for a boy over six feet to make himself look that small), so you scootch over, pulling your little pillow with you, so you can sit beside him. You smile as you pat his arm, trying to comfort him. It doesn't seem to help in calming him down, but he does look a little less depressed.

"Don't be nervous, Koganegawa-kun. The problems you have with your schoolwork aren't that difficult to fix, and I promised I'd help you, right?" You say softly. This seems to help, and Koganegawa's colour starts to go back to normal as he looks down at you beside him.

"T—Thank you, Senpai." He says quietly. Your words must have really been helping, since that was the quietest voice you'd ever heard him use.

You begin to explain all the issues you'd seen, while Koganegawa hurriedly writes down notes, nodding untiringly after every point you make. You try not to think about how cute he is, looking so determined and studious at the same time. It's a short explanation, but Koganegawa looks like he's hanging off of your every word.

"So, in short, you really only have a few problem areas, and they're not too difficult to fix. You understand the material well. However," you pause, and look at him seriously. "The material gets harder throughout the year, and it often builds on the material before it. If you don't understand something, it's very important that you ask questions, and have someone explain it to you. If you're too nervous to talk to your teacher, than talk to me. Okay?"

"Understood!" Koganegawa replies excitedly, giving you a strong, firm nod of acknowledgement.

"Good." You say, giving him a bright smile. "So, are you ready to begin?"

"Yes, Senpai!" Koganegawa grins happily. "Always ready!"

"Alright, then let's go!"

—-

"Ah! Good job, Koganegawa-kun!" You exclaim cheerfully, clapping your hands. "That was a tough one, and you answered it perfectly."

"T—Thanks." Koganegawa replies sheepishly as he shyly rubs the back of his neck. His ears are red, and you can tell he's really happy to be praised.

"Don't be shy. You worked hard, you should be proud!" You encourage him. He's still looking down, blushing, and the black spikes of his hair are sticking up haphazardly. You can't help yourself, and affectionately pet his hair.

"Good job, Koganegawa-kun." You say softly.

"T—THANK YOU SENPAI!" He yells so loudly you jump, nearly falling on your back. You stare at him as your hand retreats, and he can only look back at you in embarrassment. You gaze him in surprise, and then laugh.

"You're welcome, Koganegawa-kun." You say, straightening up. Koganegawa smiles in relief, looking down at you appreciatively. It almost seems as if he's very happy that his over-enthusiasm doesn't seem to annoy or upset you at all. He nods joyfully, and you watch him contentedly as he immediately goes back to his homework, his brow furrowing in concentration as he continues to work hard.

When he focuses, he really can do wonders. Although he still makes a few mistakes, not always able to understand what to do, he never hesitates to ask you, and you make sure to explain everything to him thoroughly. Soon, he's getting almost every question correct. You congratulate him each time, encouraging him, but each time he just seems to get even more anxious, fidgeting and staring at you meaningfully. Finally, when you confirm he got one of the most difficult questions right, he blurts out what he wants before you can even praise him again.

"S—Senpai! C—Can you do—do it again?" He stammers eagerly. You blink in confusion, and then he slightly tilts his head down. He's looking away, his face tinged with dark red, as he squirms anxiously in his seat. He looks so shy and hopeful and sweet, you can't help but feel a warm, happy feeling in your chest at how incredibly cute he is.

You understand what he wants you to do.

"Mmm…Koganegawa-kun, you must not get this a lot, because you're so tall, hmm?" You tease him, as you once again pat and ruffle his hair affectionately. He gives a small nod, still not looking at you as his entire face turns a bright red. When you pull your head back slightly, he immediately pushes his head forward, not wanting you to stop.

"Pfft!" You have to stifle your laughter, and you can see that even his ears are red by now, but he's still very happily enjoying being pet. Still, you have work to do, and after a few moments you pull your hand back. Koganegawa tries to follow with his head, and ends up overbalancing and falling on his side on the floor.

"Hey, you still need to work hard." You tell him, sighing. You try to sound stern, but it's a lost cause. Looking down at him, as he blinks up at you innocently from the floor, you can only think about how ridiculous it is that someone twice your size and a head taller than you is cute enough to have you make the same smile you normally reserve for when you see a baby animal.

"Remember? You want me to cheer for you." You rest your chin in the palm of your hand as you rest your elbow on the table, looking down at him. "I want to watch you play volleyball, Koganegawa-kun, but I won't be able to do so if your grades don't improve and you're thrown off the team. You can't relax yet."

Koganegawa immediately sits back up, nodding indomitably.

"Yes, Senpai! I promise you'll get to see me play! I'll work really hard!" Koganegawa promises. You grin, and he immediately returns your bright smile.

For the next few hours, Koganegawa really puts his all into studying. He asks questions, works hard, and puts all his determination and drive into learning the material. However, you can see the sun is slowly starting to set, and so you finally tap Koganegawa on the shoulder. He looks up at you in surprise, his head tilted slightly in confusion.

"I think that's enough for today, Koganegawa-kun. We can continue next week." You say, pulling your hand back to start cleaning up the papers on the table in front of you.

"Senpai! Please, just one more hour!" He asks you desperately, holding his hands together in a begging motion. You shake your head, and then lean back to stretch your tired limbs. You looks back to see Koganegawa staring away from you suddenly, his ears bright red, and you frown.

"Don't be mad." You say, flicking on of his black spikes of hair gently and making him jump. You sigh, and slowly rock to your feet, stretching your legs. "It's getting dark already. Come on, I'll walk you home."

"N—No!" Koganegawa shakes his head, standing up quickly. "I couldn't let you walk back home alone! So I'd have to escort you back! Although, if you really wanted to see my house, I would definitely—"

You shake your head, putting your hands up in surrender.

"No, that's fine, Koganegawa-kun. I'll let you walk home on your own, in that case." You let out a long exhale, putting your hands on your hips as you look at with an odd mixture of exasperation and affection.

He really is something else.

"Please send me a message when you get home, so I know you arrived safely." You tell him sternly. He nods enthusiastically, and then suddenly pauses.

"But…ah, Senpai I don't have…" He pauses, looking down at the phone you're now holding in your hand before him.

"Here, you can put your number in here." You say, as you hand it to him. He wastes no time in stuffing his into your hands, and you exchange numbers before you help him collect his things and walk him to your front door.

"Have a nice walk home Koganegawa-kun. Please be safe! And remember to go over the material that you were having trouble with today, alright?" You say, as you hold the door open for him.

"Right! Thank you, Senpai!" He says, flashing you an enthusiastic smile and a thumbs up.

He really is too cute.

"…You worked very hard today, Koganegawa-kun. I think if you continue working like this, you'll have some of the best grades in your class." You tell him, patting his shoulder assuredly.

"…Thank you." He respond softly. He's uncharacteristically quiet, and at first you're worried. But he's smiling at you, looking at you with a strange expression in his eyes. There are a few moments of silence before he coughs, rubbing the back of his neck awkwardly before he turns away and runs out the door.

"Goodbye, Senpai! I can't wait for next week!" He cries over his shoulder, as he disappears down the street. You stare at his fleeting form in surprise, and then shake your head, laughing pleasantly as you close your door.

Ten Minutes later…

You're just doing some studying of your own when your phone buzzes. You pick it up, and laugh as you read the message.

"Senpai, thank you very much for today! You're a great teacher! I'm so happy you're my tutor! Please continue to treat me well!"

And then, a moment after you finish reading it, your phone buzzes in your hands again.

"Oh, and I got home safely Senpai! I ran all the way home, so I could message you quickly and you wouldn't worry! Have a good night Senpai!"

You smile, as you put down your book to message him back.
