Except for one devil, everyone in math class is paying attention to the subject. She didn't really attend class with other students because of her childhood years, so it makes sense that she would be thrilled about this, but shockingly, she is bored to death.

She is confused by what is occurring and what the teacher is saying, which reminds her that she is the devil and must perform devilish acts, such as compelling a human to engage in activity that is, in this instance, counterproductive. She chuckles amusingly and turns to face the person seated next to her.

"Hey hey Yuan, why don't you sketch amusing stuff in your notebook instead of studying?"

Yuan vaguely answers, "Ah yeah..um," as his head slowly drops on his desk.

Levia went "eh?" as she looked at the guy next to her.

Yuan is soundly dozing off at his desk, his head resting on both of his hands in a sideways position. His breathing is regular. It reminds her of the time she slept in the afternoon when she was a kid.

In an instant, Levia tried to wake him up since she believed that dozing was going too far.

"U-ui, why are you sleeping? I didn't instruct you to go that far!" but her hands merely flowed through him. Not long after her, Rikko, the person next to him, begins mumbling his name in an attempt to wake him up as well, Yuan's teacher notices what's happening and begins to approach him.

"Oh no," Levia exclaimed, covering her eyes as if she is going to watch a public execution.

The teacher shouted "AHEM!" so loudly that even Rikko, sitting next to Yuan, was frightened. Yuan unwillingly sits up as he opens his eyes.

*yawn*

He put the marker on his face and said, "Yuan, you have the arrogance to sleep in my class AGAIN; it's safe to say that you already know what I'm teaching; now if you would go to the board and solve the problem." Yuan approaches the board with the marker in hand.

Levia screamed in horror, "awa waw w aaw," looking at Yuan with a worried expression.

But in contrast to Levias, Yuan solves the problem on the board without difficulty and returns to his chair.

While the class is still in session, the teacher glances at the answer on the board and exclaims angrily, "Correct, I'll let you off the hook today, but don't do it again." Yuan answers "Yes" as he walks back to his seat and gives a small sigh.

Levia looks at him, saying, "What is this hatred I feel towards you?" to which Yuan meekly replies, "That's called jealousy."

Levia pouts as they continue the rest of their day in class.

**

That evening, in Yuan's bedroom

Yuan asks in a very sluggish tone, reflecting how he really feels about this supposed mission, "So... what should I do?"

That's right, as a reward for answering Yuan's questions earlier this morning, he must assist her in completing her mission, which entails carrying out a heinous deed, or what Levia generally referred to as pulling a prank.

If you encounter this narrative on Amazon, note that it's taken without the author's consent. Report it.

This girl doesn't know that in order to achieve her goal, she must repeatedly say it to me in a way that is just like the way the devils below the stairs do it, compelling me to act on a need that came from my deepest desires. At least, that's what I believe.

However, what we are doing at this time is not at all what I want or even consider doing. If you look at it more simply, the right or usual method is for me to do something that, despite my initial reluctance, I ultimately don't mind doing. However, since it is currently coming from her rather than from me, the entire situation is flawed from the start.

"OK! "Let's start our operation!" Levia energetically punches the sky.

Yuan smirked at the naive girl's adorable face, contemplating whether to tell her the truth and put an end to her misery or to just enjoy the show.

"Okay. Let's do this, prank," he chose the latter.

She gave a thumbs up and said, "Oh, so you're starting to get into it as well."

"Now for our first prank! Let's go with the classics, and let's DO SOME PRANK CALLS!"

Yuan holds his laughter as Levia gets onto the bed and sits close to Yuan, she glances at him eagerly.

"prank calls Huh…, did you ever do this?" He wondered because he had never made any prank calls before, Levia briefly turned her head away from him before turning it back toward him.

Her face reddened a little and said, "Let's ignore the little details and just do it." In response, Yuan narrowed his eyes in return before he sighed in resignation. He gazed at her while grabbing his phone from the table.

"So... "Who are we going to prank call?" Yuan asked as Levia answered,

"your mom?"

Yuan closed his eyes with an annoyed expression, saying, "Take this seriously."

In the end, they decided to prank call one of Yuan's friends(very few friends), Rikko.

*ring ring*Yuan stares at the devil girl seated next to him, whose ear is close to the phone in his ear. If Levia is a human, they may feel the warmth of each other's faces because they are so close next to each other.

"I will put the phone on speaker so that you can hear the discussion even if you don't put your ear close to the device—I mean, I will change the settings so that you can hear it; furthermore, aren't you embarrassed about this?... I mean.."

Levia pulls away from Yuan, and she flushes as she becomes aware of how close they are to one another.

"S-say that in the first place. And I know what a speaker is: "

*beep*

"Hello, this is Yan resident. How may I help you?" On the phone speaker, there is a soft feminine voice with undertones of maturity.

The sudden, unexpected voice that was different from what they were expecting stunned them both on the spot. Yuan turned the call to speaker

Levia went, "That's not your friend," as Yuan answered, "It's his mom."

"Come on, tell her yabadabado, then hang up!" She giggles excitedly while Yuan looks at her with a face saying, 'Are you a kid?'

Yuan clears his throat. "Ahem."

Levia's face brightened up as her long-awaited prank call was about to happen. As she turned to face the young man seated next to her, she noticed a small grin on his face.

with a deep and mature voice "Hello, this is the Tights Fanatic Department, or TFD for short. Is this Mr. Rikko Yan speaking? I'm here to inform you about the delivery of your shipment,"

Rikko's mother uttered "t-tights?" while Levias' brain instantly shuts down like a computer *insert windows shutting down sound effect*

He replied confidently, "Yes, tights," in contrast to Rikko's mother, who was agitated.

"T- This is Rikko's mother and my name is Stella. Maybe this is a gift for me?" as she assumed that was the case.

Yuan almost chuckles at Stella's response, "I see."

"Anyway, your son ordered three packages, saying he is especially hungry for tights."

"eh h-hungry!? Does my son eat tights?!"

Even over the phone, Yuan can picture her pacing back and forth before continuing as she begins to fear.

"Yes, ma'am, he claimed that was his favorite, especially when it comes from a matured."

"EHHH!" Her loud voice echoed in the room.

"C-Can you cancel the order?" she asks desperately, gripping the telephone even tighter.

Yuan grabs his shirt, trying not to laugh and maintaining his mature, professional voice. "Cancel?, Why? Do you want the booty package instead? "

"NO! What I mean is, I already have plenty of tights. "

Yuan made a sound, indicating that he understands what she is trying to express. "So you're saying that you will provide your tights to your son instead?"

"Huh? NO! I'M SAYING THAT WE DON'T NEED IT!" She exclaims out of impulse.

"No offense, ma'am, but I believe the tights made by our company are considerably more appetizing than yours."

"EXCUSE ME!" Yuan almost laughed at her reply as he was enjoying this prank, but he thought that perhaps he was pushing it a little too far and that it was time to end it.

"Look, ma'am, these chicken thighs are already cooked, so we can't really cancel the order, but if you're that upset, I guess I can do something about it."

"…..c-chicken?"

"yes ma'am anyway good day to you"

*beep* and with that, the call ends.
