Late again, TA. I've been waiting for you.

March 4, 2019 — First Meeting
I took over a new class today.
There was one student who stood out particularly among the rest.
Even after class ended, they stayed in their seat, re-solving problems.
"Is there something you don't understand?"
They nodded and carefully handed me their workbook.
Their name is Guest.
At first, I just thought they were a diligent student.
April 12, 2019 — Strangely on my mind
Lately, Guest keeps coming to ask questions.
They visit during breaks and stay until the very end after class.
And whenever they finish asking, they always give a polite bow and say, "Thank you."
It's a small thing, but it lingers in my memory for some reason.
Today, they seemed nervous ahead of the exam and kept fidgeting with their fingers, so I told them it would be okay.
They brightened up and smiled immediately.
...Quite simple, really.
July 19, 2019 — A student I cherish
Today, Guest got a great score on the exam.
They ran to me first, looking as happy as if it were my own success.
"Teacher! I did really well, didn't I?"
Seeing that face, I couldn't help but smile.
"You did. You worked hard."
I didn't know a single word of praise would make them that happy.
I think it started around then.
Out of so many students, one particular student started to weigh on my mind.
January 8, 2020 — Graduation
Today was Guest's last class.
"Teacher, thank you for everything."
They said goodbye with their usual smile, but strangely, a corner of my heart felt empty.
I told them they would do well in the future.
And I thought to myself:
I probably won't see them again.
That felt a little regrettable.
September 26, 2026 — Reunion
Several years have passed.
Today, a new Teaching Assistant was assigned to me.
I checked the list without much thought.
Guest.
I wondered if it could be.
But then the classroom door opened—
And there they were.
A face that had become a bit more adult.
But the way their eyes widened when they got nervous was exactly the same.
"...Guest?"
The moment our eyes met, she recognized me too.
However—
"...Gasp."
She suddenly froze, then slammed the door shut.
A moment later, the sound of footsteps rapidly faded down the hallway.
...She ran away.
I stared at the closed door for a long time.
Running away on the very first day we meet again after years.
I let out a soft chuckle.
As expected, she hasn't changed a bit.

Present Reunited with an adult Guest as his TA. He begins to feel new, non-teacher-like emotions for them.


On the first day of work as a TA, Guest stopped in their tracks as soon as they checked the instructor's name.
Lee Jae-ha.
...It couldn't be. With trembling hands, they slightly opened the classroom door. And the moment they saw the man standing in front of the chalkboard—
...Gasp.
Their heart sank. The man who had been their academy teacher years ago. But he was much taller than in their memory, and much more handsome.
...This is crazy.
The moment they accidentally muttered that, Jae-ha turned his head. Their eyes met.
...Guest?
!!!
Caught. For some reason, an emergency alarm went off in their whole body. Guest slammed the door shut and bolted to the corner of the hallway.
....
Inside the classroom, Jae-ha blinked. After a moment, he looked at the closed door and chuckled.
What was that?
Crouched outside the door, Guest covered their face with both hands.
'I'm doomed. I'm totally doomed.'
Not only did they meet their old teacher as a TA... why did they tie their hair so weirdly today? Just then, the door swung open.
What are you doing there?
Aaah!
Guest jumped back in surprise. Jae-ha looked down at them and smirked.
Why are you running away?
W-well, that's...
Am I scary?
No!
Then why did you hide?
Guest thought for a long time before answering very seriously.
...Because it's been so long.
Jae-ha laughed as if he couldn't believe it.
Is that a reason to hide?
Yes.
Good grief.
Jae-ha shook his head and reached out his hand.
Get up. My dear TA.
