Kimetsu Academy's Love Triangle ( Muinezu & Zennezu )

< Prologue ⭐️

"All clear. You're dismissed. Next."

First Year student, Zenitsu Agatsuma, mourned in boredom as he unwillingly checked the uniforms of his peers. As a student officer of the Disciplinary Committee, his job is to check the uniforms of the students of Kimetsu Academy at the school's gates everyday to ensure that they are wearing the uniforms properly and correctly. Though, he never wanted to be in this position in the first place but somehow managed to get a job like this anyway.

In the corner of his eyes, he sees a familiar blur of burgundy and black. He whips his head around to see his best friend, Tanjiro Kamado.

"Tanjiroooo!" Zenitsu cried upon seeing Tanjiro approach him. "Please save me from this misery! I don't know why they made me have this type of job, you know. I'm getting tired of checking school uniforms every morning!"

Tanjiro smiled at him and laughed a bit. "Oh, Zenitsu, cheer up. I think it is admirable of you to be taking up such a responsible job every morning. It really shows how much of a good man you are!"

"Ah, y-you really think so?" Zenitsu sheepishly smiled and blushed upon hearing Tanjiro's kind words. "Oh, you are so nice, Tanjiro! I can't believe we are friends."

He then looked around. Tanjiro was alone. Usually Tanjiro would be walking to school with his younger sister, Nezuko, but it appears she is not with him today. "Eh? Tanjiro, where's Nezuko? Is she staying home sick today?"

"Hm? Nezuko? Oh, she is walking with a friend to school today. I figured that I'd let her and her new friend walk together because I felt like I may interrupt something between the two since they are both Second Year students after all."

Zenitsu perked up. New friend? Zenitsu was sure he knew all of Nezuko's friends. Like Aoi, Ume, Kanao, Genya, Senjuro, and many more. He couldn't help but begin to wonder who her new friend could possibly be.

Oh well, not like it was a problem anyway. Since he has the job of the Disciplinary Committee officer, he will eventually end up seeing Nezuko and her new friend coming up to the school gates. So until then, he'll just have to wait for their arrival.

"Oh, okay. I was just wondering. Let me take a look at your uniform, Tanjiro.."

It has been 7 minutes later since he has checked and sent off Tanjiro to class, and he finally saw the familiar lovely kin of Tanjiro.

Nezuko.

"Ah! Nezuko is finally here!"

But then he saw who was walking beside her. His jaw dropped.

"Who is THAT?"

Nezuko's presumably new friend was a boy, slightly taller than her, with beautiful long silky black hair with a mint hue on the tips of his strands. Zenitsu could see the boy smile at Nezuko and despite a piece of bread covering Nezuko's mouth, he could tell that she had giggled. For some reason, he began to develop some sort of a heavy feeling ache in his heart.

And even though he was the school's uniform checker, he most definitely must have checked that mint boy's uniform before, but he still did not know who he is nor recognized him. Well, that is because he doesn't really pay attention to people's faces when checking the uniforms.

"Nezukooooo!" Zenitsu wailed as Nezuko and the boy approached him. "Who is this? Is this a new friend? I have never seen him before!"

Nezuko was about to respond when her mint-haired friend spoke first.

"I'm Muichiro Tokito. Do you not remember me? You're the same man who checks my uniform every morning."

Zenitsu stood there dumbfounded, staring at the boy, 'Muichiro Tokito' , with a nervous smile plastered on his face. "M-Muichiro Tokito? Oh, sorry, but I don't think I really remember you.." But that name did stand out to him. Zenitsu could recall all the times he had heard that name.

Like that one time these group of Second Year girls he walked by were gossiping about how cute Muichiro was.

And another time was when he overheard that Muichiro received many love letters and gifts from girls on Valentines Day.

And he heard that-

"Wait a second. Why does all of the times I could remember this guy was when there were girls being all over him?"

"GAHHHHHH! It's not fair! I want girls to like me too!"

Beginning to be filled with jealousy, Zenitsu slowly crooked his head away from Muichiro to avoid any eye contact with the younger boy. He then shifted his attention back to Nezuko. Looking at how cute she was replaced the burning feeling in his stomach with a warm-fluttery one.

"Nezuko! You're so cute today! As always!"

Nezuko smiled at him and nodded her head as a way to thank him for his compliment, making "mmph mmph!" sounds with the bread in her mouth.

She then pointed her finger to herself, and at Muichiro, trying to signal something.

"Hm? What is it, Nezuko?"

"She wants you to check our uniforms so we could get to class." Muichiro spoke up.

Zenitsu furrowed his eyebrows. "Huh? And how would you know that? You don't speak for Nezuko! She should only speak for herself!" He yapped with a scowl.

"Agh, seriously! Who does this guy think he is anyway? Just because he is popular with the girls doesn't mean he could speak for them too!"

Nezuko nodded in agreement with Muichiro's statement. She indeed did want to hurry to class before the bell rang, and she was sure Muichiro felt the same way too, being that he was a good student after all.

Zenitsu sighed. "Fine, fine. Let me take a look.."

He scanned both of the Second Year students' uniforms. Everything seemed to be tucked in and in order. Nezuko's bow and Muichiro's tie was tied correctly. His eyes then shifted to their bags. Nothing peculiar here. Nezuko's bag was decorated with stickers, pins, and cute keychains, meanwhile Muichiro's bag was plain and was not decorated with anything.

Or so he thought.

Because as soon as Muichiro handed Zenitsu his bag to be checked, he saw the exact same kind of pin that Zenitsu himself had on his bag. It was the same pin Nezuko had gifted him a few weeks ago, but just in a different color. The pin Nezuko gave him was just a yellow shaped rabbit and Zenitsu cherished that pin like it was a very rare ticket to get into a popular singer's concert.

But the pin on Muichiro's bag was a mint colored rabbit.

"Who gave this to you?" Zenitsu asked, his finger pointed right at the mint rabbit pin.

Muichiro tilted his head in confusion, finding his question to be a bit random and absolutely irrelevant. "Nezuko gifted me this pin. Why'd you ask?"

Zenitsu felt his world exploding. He knew that Nezuko shared those pins only with people she considered really close to her, such as Tanjiro, Inosuke, and himself. And apparently, that meant that Muichiro was really close to her.

"Nothing. You guys are dismissed.." he grumbled.

Nezuko and Muichiro walked past him and dispersed into the crowd where the rest of the students were at in the school. Zenitsu sighed again, his fingers tracing the yellow rabbit pin that was pinned onto his bag.

"Nezuko couldn't possibly like Muichiro like that, right?"
