Tick... Tock... Tick... Tock...

You block out the white noise that encompasses the entirety of the classroom; the white noise being⁠—in your vocabulary⁠—your Math teacher, Mr. Ishikawa. You couldn't be bothered to listen to his discussion anymore, seeing that you've been so lost in thought for at most the initial 15 minutes of his class that you practically cannot catch up with the rest of the students. So why not spend the remaining hour doodling and watching as the clock hand goes by? And that, you did.

The middle-aged teacher had noticed your aloofness from the corner of his eyes. He knew that you weren't paying any attention to the lesson at hand, not to mention that you were in contrast to the sea of students who had their heads buried deep in their textbooks. Your [e/c] irises were blankly staring at the wall clock located at the front of the class, just above the board. If others were to observe, they would be convinced that you were paying attention to the mathematical equations scribbled on the chalkboard. In a nutshell, you stuck out like a sore thumb.

The man sighed, easing his headache by gently massaging his temple. The midterms were coming right up, and he feared that his students wouldn't have enough time to prepare and study for the test. To say that he's slightly concerned is an understatement; he's anxious for them. The majority of students had problems with the Math lessons this semester, and he couldn't blame them. Imagine having to memorize more than 10 formulas and being expected for to stay with you until you use it on exam day. And that's not all, you also have to familiarize yourself with the terms used and avoid confusing it with another.

He knew that his students would pay attention to the lesson and try to catch up as much as possible, but what he didn't expect was you be absentminded and have your head up in the clouds in his subject: Mathematics. Mr. Ishikawa never doubted your intelligence as a student; you are averaging and have no problems with Math, though a bit confused at times, but nothing that you couldn't get your head around. However, at a critical time like this, he can't help but reprimand your behavior later.

Ding... Ding... Ding... Dong...

Finally, the awaited hour at last. The school bel⁠l's chimes resonated around the whole campus, enveloping the students and faculty members alike with its gentle, relaxing tune. A sigh escaped your pink lips as you glanced at the time for the last time. 3:15 in the afternoon, meaning, the dreaded period has ended and you can finally go on to your merry way. Mr. Ishikawa stood up from his seat and faced the students, addressing his concerns about the upcoming exams. After, he had dismissed your class.

You immediately fixed your belongings inside your black shoulder bag⁠—not that you have a lot to return inside since you zoned out from the last period⁠—and stood up from your seat. Bringing the strap over your shoulder, you watched as your classmates headed out from the back door, leaving only a few, you included, inside. You were about to take a step towards the exit when a stern voice called you.

"Miss [L/n]."

You visibly flinched at the tone of his voice—serious and firm. It was the usual setting between student and teacher, although the way that it was delivered to you made you unsettled. It's like you've been caught red-handed by your parents, only this time, you didn't even know what you did wrong.

You whipped your head back to the older male at his table, dark blue eyes boring holes into your soul. You were tense but still decided to wear a convincing confused front, masking your anxiety effectively.

"Yes, sensei?"

"Please come here for a second. I need to address you about something."

The way that he motioned you over or the fact that he had his finger on his temple didn't look like it was going to be good news of some sort. You swallow a small lump in your throat as you saunter to where the teacher is. You surely didn't get into trouble, right?

"What it is you wanted to talk about, sensei?" You cautiously queried, becoming more anxious than you already were.

"Miss [L/n], I know that you're a hardworking student and your grades in Math aren't that bad. However⁠," Mr. Ishikawa spared a glance at his student, observing your bodily cues. "⁠—it seems that you weren't paying attention in class today. Is something the matter? I know that lessons this semester are quite difficult, but please be aware that midterms are approaching. I don't want your grades to be in danger, especially in my subject."

You pursed your lips at his words. You didn't hate him or his subject in any way. Although Math has given you quite the difficulty⁠—no, wait, scratch that⁠. It is literal hell⁠—you still manage to bring your grades up even just a bit. You consider yourself as just average in the subject, not that smart to constantly have an achievement, nor dumb to fail. It's just so-so, enough to let you pass. However, it seems that your grades are suffering and on the verge of failing.

You weren't so sure what the cause might be, or if you were to blame in this situation. Nevertheless, the news is certainly not good for your ears to hear. You glanced at the oakwood floor for a while, before returning your attention to the teacher.

"I'm sorry, sensei. There's nothing wrong. I just feel overwhelmed with the subject that I tend to space out," giving a sincere bow, you explained your reasoning.

Mr. Ishikawa's calculating gaze didn't leave you for a bit, making you shuffle slightly in your spot. He then let out an exasperated sigh, his hand waving dismissively. "No matter, it doesn't change the fact about your grades and midterms. If things were to continue like this, you'd surely fail my subject. I'd recommend that you have someone to tutor you in the meantime, in that way, you won't fail."

The male before you gave you a knowing look. You weren't quite fond of having a tutor, to say the least, especially when if it's someone you don't know. But, what other options do you have? It's not like you want to fail in your second year of high school. So with a squeamish heart, you spoke, "...Alright."

"Great. I'm sure that Mister Ishigami won't mind tutoring you," with that said, Mr. Ishikawa flashed you a smile as he fixed his books.

Pink flushed across your cheeks at the mention of the student. Sure, you and the leek-haired genius were friends for like, years. But just pondering about the thought of him tutoring you sent you into overdrive. You secretly had a crush on the male since but didn't have enough courage to confess the feelings. Just acting normal was tough when every time, you're being assaulted by your hormones to do something intimate to him. So spending time with him tutoring you was something you haven't imagined, even in your wildest dreams.

The sudden screech of metal against the wooden floor broke you out of your trance. Facing the teacher once again, he patted you on the shoulder and stepped out of his seat, pushing the chair further into the work desk.

"I'll be leaving now. Be careful on your way home, Miss [L/n]. And please don't forget our discussion, alright?"

You bowed your head. "Yes, sensei."

"Good," a smile etched on his aged face.

Your gaze trailed upon Mr. Ishikawa's back as he walked out the front door, probably heading back to the faculty room. You let your eyes linger on the closed sliding door, before releasing a huff of annoyance. Gripping your bag strap, you trudged over the aperture and exited the classroom.

The hallway was seemingly empty, considering that your earlier discussion took more than five minutes. Your [e/c] eyes observed the surroundings as you walked⁠—cream-colored walls, wooden oak floorboards, metal plaque located above each room to indicate the room name, and sliding doors with windows. You muttered in each room as you passed by them, boredom lacing in your tone.

"Class 2-2, class 2-3, literature club, library..." An exasperated sigh escaped your lips after, noticing that there was no more classroom by the end of the hall.

Your feet immediately turned a swift left into another hallway, only this time, you were met with a familiar person. You recognized the skinny young man with his iconic anti-gravity leek hair with two locks that drape over his face. He had his hands in his pockets while staring at the floorboard, seemingly lost in thought⁠—you noted. Yet, despite him not noticing you, just the sight of the teenager made your face flush.

Eventually, the student turned his gaze to the front, landing on nothing else but you. The surprise was written over his expression, but he nevertheless smirked at the sight of his best friend. "Well, isn't this a surprise? I was 10 billion percent sure that you're on your way home right now."

You playfully rolled your eyes at him, stopping just a meter from your best friend. "Well, apparently, your calculations were off since I'm here right now."

"Let me guess, waiting for me?" the male said, placing his hand on his chin as if thinking. Though the smirk on his face never left, making your blush redden.

"Sorry, but I wasn't boy genius," you let out a scoff, crossing your arms as you tried to cool down your cheeks. "I would be delighted if that's the case since you're nowhere to be seen during the last period. Speaking of which, where were you during Math?"

"Since the school's Science competition is nearing, every teacher gave us, the Science club, permission to spend the last period preparing for the competition," Senku explained, placing his hands on his hips as he did so. "So being the club president, I was at our club room for the hour."

You nodded in understanding. But soon, your lips contorted into a pout, eyebrows creasing to accentuate your hidden indignation. "How nice. I wish I could escape the Math period as well."

"Silly," without warning, Senku flicked your forehead which earned him a surprised yelp. "You know that you can't just skip the subject. So tell me, what makes you upset this time?"

Despite Senku's remarks and occasional forehead flicking, you knew that he was genuinely concerned about you, especially your studies. Sure, he would appear arrogant and overbearing, often annoying you about your oh-so-average grades, but there isn't just a moment when he didn't help you improve. Not to mention that he's so observant about you that he can point out your cues and even know what you're feeling at the moment. That's why you admire the boy so much.

A frown replaced your pouting lips at his words, slumping your shoulder a bit. "I was held back to discuss something with Ishikawa-sensei."

"And that is?" he quirked a brow, prodding you to explain further.

"Ishikawa-sensei told me about my grades, and apparently, it's suffering. So for me to pass the upcoming tests, he advised that I should get someone to tutor me in the meantime," an annoyed sigh escaped your lips after that statement.

"If that's your concern then you don't have to worry about it too much. Overthinking might lead to losing more brain cells."

"Hey!" you shouted at him, offended by his sarcastic remarks.

"No need to shout at me, [Name]. Geez! I was only joking," he pulled up his hands in surrender. "Besides, you already have me. Who else helps you study, silly?"

Your [e/c] hues stared at the male's face, still not quite convinced. A pout graced your lips while your cheeks were red in embarrassment. Eyebrows still creased up, indicating your agitation. Senku didn't bother to move an inch under your heated stare. The boy knew all too well about your tendencies and antics, and this one of them.

The moment lasted for another minute when Senku broke your trance with his iconic smirk. This made you blink in surprise as realization fell on you; you'd been staring at your best friend's devilishly attractive features for too long. You instantly flared at this, moving your head back while averting your gaze somewhere but him.

God, couldn't you be a little more cautious around him? You're ogling him in front of his face! Isn't that super embarrassing? Whatever excuse your head came up with, you couldn't justify your earlier action by any means. So instead of speaking, you decided to remain silent until he spoke first. Damn, your teenage hormones.

"What? Too embarrassed to have me as your tutor?" Senku mused. Despite you being unable to see his face, just hearing the teasing tone of his voice is enough to know that a smirk was still on his face.

You were close to snapping back at him, but you held your tongue back at the realization. It dawned on you a moment after his claim that he was volunteering to tutor you in Math. You were beyond baffled. Sure, the two of you occasionally spend time reviewing and studying, but that was way too long ago. Considering that he's always busy in his club and studies, you concluded that you should just leave him be⁠—not bothering to ask him to help you study.

"Wai⁠—w-what?" you whipped your head back at him, face covered in a red hue.

Senku just sighed. "You told me about your grade problem, right? So to help you study, I'll be tutoring you starting today."

Your eyes widened at his claim. Surely, your mind isn't just making up the scenario, right? Admittedly, due to your annoying hormones, you once imagined being tutored by this leek genius at school in private⁠. And not only that, but your dirty mind also added another scenario following that. But we'll never speak of it any further.

"Can't it be tomorrow?" you whined, pleading him with your puppy eyes to at least let him save you from further embarrassment. Who might know? Your hormones might initiate something you wouldn't want to happen.

"No, the earlier, the better," he retorted, grabbing your hand and dragged you inside an empty, unused classroom. "You will improve quickly this way, I'm 10 billion percent certain."

You just swallowed a lump in your throat as he led the way, nervous sweat rolling down from your forehead as your heart sped up. Your head was swirling with dirty thoughts and different scenarios. Once the two of you entered the room, you shook your head, ridding yourself of those thoughts, and tried to focus on the situation at hand.

Your eyes observed the classroom⁠—even though it was unused, it wasn't overall bad. The room had a total of 20 desks with five chairs in each row, a rather small chalkboard on the front, a shelf that stores personal belongings at the back, and a storage cabinet at the farthest corner. You sat on an empty chair in the front row as you were instructed to. Taking out a notebook, the Math textbook, and a pen, you then set down your belongings on the table while placing the bag on the ground.

A frown made unto your face at the idea. Sure, you wanted help with your current problem, but you aren't that obliged to start the tutoring session right away. You thought that maybe you could have a day or two without worrying about your brain exploding from information overload. Though it seems that Lady Luck has long abandoned you.

A comfortable silence settled between you two. Senku scanned the vicinity to find⁠—what you guessed as⁠—chalks while you were watching him. You hadn't noticed it earlier, but now you knew that the male wasn't wearing the usual uniform, nor his iconic lab coat.

"Why aren't you in your uniform, Senku?" you asked, trying to spark up a casual conversation before getting down to studying.

"We made a miscalculation with the project, and then one thing leads to another, then kaboom⁠—" the leek-haired replied, rummaging through the storage cabinet and found the item he's looking for. "⁠—We're all covered in dust that's why I decided to change."

"Oh."

"Anyways, let's start," Senku announced as he made his way to the front. "I'm guessing that the lesson is still about 'Estimation of Parameters', right?"

You nodded in reply, opening the textbook to what you assumed was the last lesson discussed. "Ishikawa-sensei discussed 'Calculating the Confidence Interval', I think. I wasn't listening."

Your best friend let out a disapproving sigh. "No wonder you need a tutor."

"Eh, not my fault that Math's scummy and difficult to understand," you scoffed, rolling your eyes at him.

"No, it isn't. You're just not paying attention during lessons," he deadpanned.

"No. And yes, I'm paying attention. Why do I even pass the exams if I wasn't?" you quipped back.

"Who knows? Maybe it's just your abundant amount of sheer luck," the male shrugged before facing the board. "Anyway, I don't have even a millimeter of interest arguing with you. So please listen to me as I review the basics of this unit. We don't want you to fail now, do we?"

The deliberate side glance Senku gave you made you huff in annoyance. You were about to resort to another snappy remark earlier if it wasn't for his immediate interruption. You two knew all too well that once either of you started something, it wouldn't be the end of it. So instead of a peaceful study session, it might've ended up in a full-blown squabble between you two. Slumping deep in your seat, you watched as Senku scribbled formulas and definitions on the board with a blank look on your face.

Senku started to re-discuss the lesson shortly after, with you trying to catch up with his explanation and take some notes as he continued. The male would often pause or slow down his speech as he waited for you to comprehend the lecture. He would also approach you and inspect your progress, checking out any errors that you've made and aid you with some tips for the solution. At first, it didn't seem so bad, until you came to a certain point where your brain could not grasp the new information anymore.

It didn't take you an hour to zone out from the seemingly long lecture. The fact that the young scientist was busy writing down the next sample problem gave you the spare time to take a trip to fantasy land. The scraping of the white chalk against the wooden board was the only sound that you could hear.

"First, identify the variables before substituting the formula. It's crucial to know which is the mean, standard deviation, and the sample size," the teenage male instructed, writing down the solutions with his left hand resting on his hip.

You began to tune out his voice by this point, boredom was visible on your blank [e/c] irises that were staring downward. You propped up against your right elbow on the table, resting your cheek on the base of your palm. Holding up the pen in your left hand, you let your thumb graze the tip before pushing it down.

Click! Click! Click!

Senku turned around at the soft sound that distracted him, his crimson hues landing upon the female he was tutoring. He noticed that you've let out a disinterested sigh, continuing your small ministration. Senku's eyebrow twitched a bit, silently face-palming—you will surely be the end of him.

Tap. Tap. Tap.

Footsteps echoed inside the room as a certain male trudged over to where his best friend sat. Once he's in front of your desk, he gently—but still making sure to produce enough sound to alert the girl—slammed his right hand on the wooden table while the other made its way under your chin. Placing his thumb below your parted lips and folded index finger below your chin, he slowly lifts your head, forcing you to make eye contact with his mesmerizing ruby jewels.

Your cheeks heated up at the unexpected intimate gestures; your eyes were wide as saucers as you willingly stared at Senku, your soft lips were parted out of shock, your heart racing inside of your chest, while your brain could not comprehend the situation at hand. Senku's face was just a few inches from yours, making it accessible for you to observe his flawless features; the stray locks of greenish-white hair that gently draped over his face as his eyebrows were scrunched up in a frown, crimson orbs contained disappointment and concern. You could've sworn that you weren't even breathing at this point due to the unexpected turn of events.

"[Name]..." he started, voice gentle as he chided you. "How can you pass the upcoming exam if you don't pay attention to me?"

You could've sworn that your brain interpreted that differently. Surely, he only meant about him explaining the lesson, right? But then why did the red hue across your cheeks darken? And most importantly, when did he start to sound so concerned about you? If you could remember correctly, never did he ever do this kind of thing to you. Like ever. So why the change? Honestly, your mind was brewing a lot of questions that you're pretty sure wouldn't get answered at all.

The two of you stared at each other's eyes for another minute before you broke the interaction by shyly averting your gaze away. You pursed your quivering lips, the sound of your heartbeat ringing in your ears. Senku disregarded your initial reaction and decided to pull back. He isn't an idiot; he knew that you were a bit uncomfortable and flustered at his action.

"[Name], you need to pay attention when I'm teaching. Or else you won't pass the midterms," the male sighed, pulling a nearby chair and setting it beside the girl, sitting on it after. "Maybe it's better if I teach you this way."

However, you didn't respond to his remark, feeling your face flush red at this proximity. Senku resumed tutoring you—his whole attention on you and your notes which you found embarrassing. You didn't hate this setup, however, it made it difficult for you to focus on the lecture when your [e/c] hues kept stealing glances at your crush.

An hour later, the young genius eventually ended the session. Both of you prepared to go home—you fixed your things while Senku erased the writings on the board. After that, the two of you exited the room and walked in a comfortable silence through the halls. Your [e/c] hues glanced outside the window, witnessing the sun descending behind the horizon. The palette of orange, yellow, pink, and violet decorated the evening sky, providing you a sense of warmth and serenity. Your mind wandered back to earlier events, a slight scarlet hue spread across your warm cheeks.

Letting out a contented sigh, you gaze back on the front. By this time, you've noticed that you and your best friend were out of the campus and heading home. Once more, you stole a glance at the male beside you. Senku was facing forward, his ruby orbs intently locked on the path both of you were heading. The way that the yellowish-orange rays adorned his features gave off a gentle glow. You didn't notice a small smile tugging at the corners of your lips at this sight.

"Well, this is home," you chirped once the two of you arrived at your street.

Senku halted at your announcement, his eyes landing on your petite back. You stayed standing for a moment before turning around to the male and stepping closer into his personal space. Senku closely watched you as you leaned in, pressing your soft lips against his pale cheeks. It happened so quickly that when the male finally registered the occurrence, you were already on your heel and ran away from him. His cheeks bloomed to a shade of scarlet at your bold gesture. Surely, he wasn't expecting this interaction to happen.

A smile adorned his handsome features, soft crimson hues staring at your faraway silhouette. "Well, this is exhilarating."
