You're only in my way (Nagisa x Assassin! Reader)

Class Full of Idiots

(y/n)'s POV

I wake up, already being annoyed. Gosh. Irina walks inside the room, to check if I am already awake.

"Good morning (y/n)- san" she says smiling.
"Good morning, Irina. How did you sleep?"
"pretty well. Oh, I have a request"
"Yes?"
"I asked already headmaster Asano, but could you help me with english classes. I am good, indeed, but-"
"Of course you are"
"-but they seem to hate me, and not so much you, so you maybe could make them listen and behave? Just sometimes, because I know how much you hate them, and I don't want to cause you too much trouble. Please?"
"it's you who asks, so fine, but only once in a week, if even that."
"Thank you, (y/n)- san!" she smiles, and gives a hug to me.
"Then, shall we eat breakfast?" Irina asks.

I dress up, and go to the kitchen. Eggs, bread, and pancakes. It's weird to eat food like this in Japan, I guess, but well, I'm not Japanese, and if I remember right, she's not either. I eat peacefully talking food with her, and after I'm ready, I take my schoolbag, and leave to school.

"Wait for me!" Irina yells, so I stop. She comes to me, and we walk to main campus together, since my first classes are anyway here. English lesson is the last class of the day, so that's fine. I anyway am the second best, so no one cares if I'm not in some lessons, especially if principal says it's fine.

I have five lessons today. They are
Japanese
Biology
Geography
Music(chosen lesson)
English (should be still music)

So maybe I'll survive.

I get many requests for helping at breaks, and I help, though I might send them to Asano, who's at my class. And when the first lesson of music is over, I go to the mountain, all the way to class E. I hate this.

When I'm at my destination, one of them comes to me, saying hi. But guess what? I ignore her. Like, no, I don't want to talk with you.

I go straight to Irina, and see Karasuma-sama as well.
"Hi, Karasuma-sama. How have you been?" I ask, but without any kind of smile.
"pretty well." he says, and turns then to Irina. "your lesson begins soon, tell miss (L/n) what she has to do", Karasuma-sama continues.
"Could you please decide are you calling me (l/n)- chan or miss (L/n) for this job. It's annoying when you change the way you call me."

Karasuma-sama ignores me, and Irina begins explaining what I have to do. So, I have to get everyone to listen, and if they don't, I will start teaching. They will regret everything they've done, if I have to do it. Which means, I will stop caring if they don't listen to me, and in the end of the lesson, give them a test that's difficult, but I will teach everything of it in the lesson. And everyone who gets over 90 points, I will buy one thing, anything they want, as long as it costs under 100 euros, because they won't get.

Well, lesson begins, and I watch over them, studying music at the same time. It didn't take even five minutes, before class is starting to be restless, and by that I mean they are starting to bother me. Gosh. Anyway, after they've gotten on my nerves about ten minutes, I stand up, and slam my hand on the table. Now, the class is quiet.
"You, be quiet, do whatever Irina-san gave for you to do and listen to her, or I will start teaching you once every week, and that's when you will start pitying yourselves, and regret what you're doing right now. Did you understand?", I practically yell at them. "And if even one of you continues talking at the class, or getting on my nerves, I promise the whole class will suffer", I continue, looking especially at Akabane and Terasaka. Then I sit down, and continue reading.

This class never learns its lesson. They're talking again. I stand up again, and walk to be in front of the class. "quiet! Let's start this lesson again. I don't care if you don't listen to me, but for your own good, listen to me Anyway", I say, but the 3-E doesn't even listen to me. Oh well, their problem. I begin explaining things, and after they have 15 minutes of school left, I hand over tests for everyone. "Okay pupils, do the test, anyone who doesn't pass will be here after school in detention. Understood? And anyone who passes with over 90 points, will get anything that costs under 100 euros, which I will buy. And if you think the test is too hard, think about how much easier it would look like if you'd have listened to me, since I taught everything of it"
