Today was my first day at Pureureuk High School.

It was my first school as a teacher. I wasn't even used to the smell of new textbooks yet, and I had no idea what kind of students I would meet or what kind of colleagues I would work with. Nevertheless, I was more excited than anything.

I checked my supplies several times since the day before, picked out my outfit, and left home earlier than usual for fear of being late. That's how I finished my first commute, perfectly prepared in my own way.

After arriving at the school, I stood in front of the faculty office I was directed to.

I took a deep breath and reached for the doorknob.

At that moment.

Click.

Before I could even open the door, it opened from the inside.

And something walked out from beyond the door. At first, I wondered if it was even human.

He had an incredible physique. Extremely tall with broad shoulders—a massive frame that would immediately draw all eyes if he stood among the uniformed students.

On top of that, he was wearing a flashy patterned shirt with a few buttons naturally undone.

I instinctively looked up.

And the moment our faces met.

All thoughts stopped in my head.

Thick, dark eyebrows. Eyes looking down sharply. A rugged jawline and a blunt expression. He looked intimidating. Very.

No, to be honest, he was just terrifying.

With that massive size, scary face, and flashy shirt.

The tension of the first day and the wariness of a stranger surged all at once, and my instincts moved before my reason.

"Aaaah!! There's a mobster in the school!!!!"

My scream echoed through the hallway.

The man's movements stopped dead. A short silence followed. With one eyebrow raised very slightly, he slowly lowered his head.

A stranger was looking at him, pale with fright, reaching only up to his chest.

It was obvious at first glance that they were a new teacher.

The neat attire, the face full of tension. And the shocking word they had just spat out at him.

"Mobster?"

A low, dry voice echoed in the hallway. It was a flat voice with almost no emotion felt in it.

However, when that expressionless face and excessively low voice combined, the situation became even more chilling.

He tilted his head slightly with one hand in his pocket. His expression still hadn't changed. He looked as if he was seriously pondering why the person who just called him a mobster had reached that conclusion.

It was then.

"Ah, Teacher! There you are!"

Urgent footsteps were heard from afar.

The teacher who was supposed to guide me through the school came running, panting. And as soon as they stood between the two of us, they froze for a moment, seemingly grasping the situation.

"Ah..."

A short silence.

"Teacher, this person isn't a mobster..."

I swallowed hard.

"He's a teacher at our school."

In an instant, my mind went blank.

Staff.

Teacher.

Not a school mobster, just a teacher.

Only then did I realize what I had just said.

First day at work.

First meeting.

And the first words.

'There's a mobster in the school!!!!'

The guide teacher smiled awkwardly and hurried me away from the spot.

The massive man's gaze seemed to follow me for a while from behind.

I couldn't say a word even as I walked down the hallway. The previous situation just kept replaying in my head.

A new teacher who screamed "mobster" at a fellow teacher they met for the first time on their first day.

Could there be a more perfectly ruined first impression?

I thought to myself as I walked blankly down the hallway.

Wow.

I'm seriously screwed.
