Senpai! You're Mine [Killua x reader]

Teaching the Kouhais

(Y/n)'s P.O.V
It's already 2 days since our break up and that remarking event. Knowing that my past memories have already awaken, my feelings for Ryuji led to confusion......

and I even used to call him, Yu-kun.... Those puppy love days though. I shook my head, feeling all stressed out. I tried to call my mom, but she wasn't responding. I guess this weekend, I have no choice but to go there myself.

"Hey. Are you listening?" Ryuji waves the paper right on my face. Did he also have an amnesia or something? It seems like he doesn't recognise me, even though my name's (Y/n) (L/n) which is the same with his dear childhood friend's name. Maybe he forgot. It's been a couple of years after all.

"Y-yeah." I've been avoiding meeting his gaze since then.

He clicked his tongue. "Right. Goodluck then." He went ahead, downstairs.

He's making me conscious and all sensitive and I can't help it, coz I've known him before and now that I regained everything, it was damn awkward, but I'll adjust very soon....

Like how can I act normal around him after knowing all that?

Should I ask him about--

.....Alright, maybe next time. (?)

I slid the door open, entering the junior's classroom. In all of those classrooms why did it have to be his classroom?

For this day....

I'll be discussing a certain subject.

A subject which I don't hate..

Yet a subject I also don't like much...

Their teacher wanted me as his substitute and it's a part of our individual performance task as well. I can feel that this will gonna be tough. A teacher's job is not a joke after all.

"Hey guys. Guess what? .... I'm given a task to teach you math just for today." I greeted them with a lively aura. "I'm (Y/n) (L/n) and as you can see... I'm your senior." Well obviously cuz I'm wearing a senior uniform.....

I am trembling so much internally, wishing to end this day already.

They all beamed up, acting too casual. "Heck yeah!!" "This is great!" "Nice to meet yah!" They continued to cheer while clapping their hands. I think they're just happy about the fact that their original adviser won't be able to lecture them— He's pretty strict after all...

I sweat-dropped.

"SHUUUT UP!"

They all automatically went dead silent after a certain girl stood up on her own desk as her dominating personality gushes out.

O.o 

Anna??

From the looks of it, I guess she's the junior's rumoured— Evil President.

Gon immediately swooped her off the table while the others wore frightened expressions except for Michi......and.....Killua...who is SLEEPING.

Rude...

My hand reflexively grabbed the black board eraser and I threw it directly at him. He lifted a hand and easily caught it, slowly raising his head afterwards. "What the hell was that fo--" His expression changed into a surprised one, dropping the eraser. "(Y/n)?" ...

*ahem* "Please refrain from sleeping on my class." I narrowed my eyes and walked towards him, getting the eraser back. 'I would like to take this as an advantage and give him some nasty punishments ....for personal reasons...'

I sighed. No can do...

"H-hai" he replied, still confused.

*Time-skips*
*Lesson begins....*

"So as you can see, just transpose the 'X' in order to simplify the equation." I discussed while writing on the board. "Like this and then square the--"

A hand was raised up.

"Yes?"

"Why does it always have to be our 'X'??" Shizuka spoke with her signitured smug look. I forgot.... she's also in this class... not to metion, Killua's seat-mate. Is she implying something? Now that he's my ex....

Her imprudent question entertains and encouraged others to open some irrelevant topics.

I'm beginning to feel flustered. "Do you have an 'X'?" A guy asked from the right side. "Don't you get tired from solving just to find your 'X'?" Someone from the left also asked while they're wearing cheeky grins.

The evil prez seemed to burst out again.

"Enough." A sharp tone sliced through the noise. It came from the silverette who toned them down instead.

"Mhn... Oh come on, we are just having a bit of fun since the lesson is becoming boring~" the b*tch beside him poked his cheeks. "Yeah, you'll really get bored....... Since you're too dumb to understand this topic." He replied bluntly, embarrassing her from the whole class as they laugh.

'Burn'

He shifts his gaze upon me and his lips curved up into a half smile. I unconsciously smiled back. "T-that's mean!" She jolted up, getting pissed, storming out of the classroom just as the bell rang.

"So..... That's it for today. Thanks for participating well!" I flashed a bright smile, dismissing them.

Wait... No. Why am I suddenly in a good mood?

"Senpai!" The brunette tackled me for a hug. "Hehe~ serves her right." She whispered.

"Anna..." Gon sweat-dropped.

Author's P.O.V
"But it was trueee... I know you agree as well!" She insists, holding both his hands with her eyes on fire.

Gon backed away. "Uumm...... Ah, where is senpai?"

Anna turned around. "Eh? She's gone." She pouted.

"Didn't you guys noticed? Killua stole her just now." Michi butted in.

"Hey.... Hey...I said Hey!" You squirmed. He's carrying you on his right shoulder with no sweat at all. "Stop! They're all looking.." You half shouted. "I. Don't. Care." He spanked your ass. "Quit it or you'll fall." He added.

You gasped, making him smirk. "Y-you. Quit. This." You growled. "Why are you doing this??" He finally placed you down on the ground. "Let's end our sufferings." The tormented male embraced you, letting you feel how much he wanted you. "I'm at the verge of getting insane." He whispered.

"But.... This is selfish of you." You began to tear up. "Let's run away." He cupped your cheeks, caressing it lightly and saying words like that too lightly.

"I wish it's that simple...but...It's impossible...just stop." I peeled his hands off my cheeks and walked away from the desperate guy.

"We're done." I gritted my teeth.

(Y/n)'s P.O.V
*pat*

A hand was placed on my shoulder. Ryu's hand. "(Y/n) what are you doing let's--"

I ran away from him.

I don't want to deal with these two anymore.... I can't deal with these emotions, issues or anything right now!
