Wait, why are you here, Noona?!
【Guest's Monologue】
They say people remember temperature before they remember faces.
Strangely enough, I felt that statement was true.
Five-year-old me cannot clearly remember that girl's face.
What her eyes looked like, how long her hair was.
Even the clothes she wore that day are blurry. But strangely.
Only the warm fingertips that held my hand are still vivid.
The person who smiled and pressed a piece of candy into the hand of my crying self.

The kindest girl in the world. That one small act of kindness changed my entire childhood world.
Time passed.
The seasons changed countless times.
Names. Faces.
They gradually faded from my memory.
But strangely, that warmth never disappeared.
Maybe that's why.
Perhaps 'first love' isn't the memory of loving someone, but the memory of being loved by someone for the first time.
And.
I believed that person would never appear in my life again.
One day as spring was ending. The classroom door opened.
"Hello. I am Seo Eunha, and I'll be your homeroom teacher starting today."

At that moment. The time I believed I had forgotten began to breathe quietly.
It wasn't that I recognized her face. It wasn't that I remembered her voice.
Just.
An inexplicable familiarity. It felt as if the spring sunshine from a long time ago was standing before me again.
And after school on the first day. Meeting her behind the school field. She was much clumsier than I thought.
She stood before the students even though she was scared. She almost fell but reached out to protect another child first.
Even when books spilled from her arms. She didn't pick up the scattered papers. She reached out her hand first to the terrified student.
That sight...
Was so foolish.
So. I couldn't take my eyes off her. A thought suddenly occurred to me.
Like that girl who watched over my tiny back when I was little.
This time...
I.
I want to protect her.

"Guest is mine!!"
Most of the cherry blossoms had already fallen.
The school in the late afternoon, after all the children had left, was strangely quiet.
A breeze seeped through the open window at the end of the hallway, and a lone soccer ball rolled slowly across the playground.
First day at work. First time as a homeroom teacher. First class.
Seo Eunha smiled slightly, relieved that the clumsy day had ended safely.
It was then.
"Hey, fucker. Can't you understand plain Korean?"
A low, rough voice was heard from behind the school field.
A dull thud followed.
Thump.
"I'm... I'm sorry..."
"You think 'sorry' fixes it? Are you kidding me?"
Pfft.
A kick followed along with a sneer.
Seo Eunha slowly turned around. Behind the school field.
Four students in school uniforms were surrounding one boy.
A student grabbing him by the collar. A student laughing while holding a phone. A student watching with arms crossed.
...Hey, guys.
A small voice. The students turned around simultaneously.
"Huh?"
"Who's that?"
"...Isn't that the new homeroom teacher?"
One student let out a hollow laugh.
"Wow... talk about shitty luck on the first day."
"Teacher."
"Just leave while we're being nice."
Instead of answering, Seo Eunha took a step forward.
