As soon as he got off the mountain train to the top of Jungfrau, Lee Ho ran across the pure white snow field, cheering.
Eunsil tapped her front paw with her eyes as if she was amazed at seeing them for the first time in her life, then looked up at me and meowed.
"Why? Are you asking me to hug you? Eun-sil, your feet are cold."
It was warm to hold the silver-gray furred Eunsil tightly in my arms.
It was my first time seeing snow in real life too.
I'm already excited because I think that Christmas, which is coming tomorrow, will be the white Christmas that I've only heard about.
The large, colorful tree installed in front of the observatory was particularly sparkling.

Eun-sil, lowering her posture, groaned at a small rock a few steps away.
“What’s wrong? What’s over there?”
Eun-sil, looking nervous, approached the rock without saying anything.
I also held my breath and followed Eunsil stealthily.
Behind the rock, a small, light brown ball of cotton wiggled.
When Eunsil stretched out her front paw and touched it, the cotton ball jumped up.
It was, unexpectedly, a living animal.
It had a long body like a weasel, short legs, and a long, thick tail.
It had a strange appearance, half cat and half dog.
It was an animal I had never seen before, but it looked like a baby, being only the size of two fists.

“You, who are you? Where on earth did you come from…?”
No, how do we look?”
Only then did the girl let out a soft scream as she noticed me.
"Oh my goodness, you're from the past? Oh, but how did Mia's button work? That button only responds to people who've been in a time machine..."
“A time machine? You… are you from the future?”
--- p.16~17

Suddenly, the world before my eyes began to swirl like a haze.
The swaying grew more intense, and a thin gap appeared in the air.
My mouth fell open at the unbelievable sight.
A deep darkness was visible through the gap that was widening.
It felt like the hairs on the back of my neck were standing on end.
Then something suddenly popped out of the darkness.

--- p.19

It was I who rode a time machine and changed my mother's unfortunate past.
It was a happiness I had worked so hard to find, so I couldn't just let it disappear.
In order to protect my mother, I had to come to my senses from now on.

“They say that thirty-three hours is the maximum amount of time you can endure.
As we saw earlier, if we step forward ourselves, space-time will become even more distorted.
“Excuse me, but could you please take Mia to me before that?”
It seemed to refer to the time when Annie was trying to exit the time tunnel, the air split open and the ground shook violently.
He said that since he couldn't take Mia himself, he wanted her taken to Mirae Park.

--- p.25

Lee Ho stopped, pointed to the mountain peak, and shouted in surprise.
“Seorim, look over there.
“The ice cream is disappearing!”
I turned my head and couldn't help but gape.
The white snow that had been covering the mountaintop like soft ice cream until just a moment ago was slowly melting away.
My legs began to tremble with an ominous feeling.

--- p.27

Lee Ho shouted, holding out his wrist.
“Look at this.
“The color of the carbon bands has turned red.”
It really was.
The display on the carbon band had turned red, indicating 'danger'.
Eunsil kept groaning as she watched the backs of the two people.

--- p.35

The thought made my hair stand on end.
Looking back, I saw a man half-leaning out from the back of a moving train.
He seemed to be looking around for us, his head turning here and there.
Next to him, a blonde woman was seen trying to stop the man.
The train was already moving away at a tremendous speed.
The moment he thought he couldn't chase anymore, the man threw himself from the moving train.
Then he got up and ran quickly along the tracks to the platform.

--- p.42~43

I wanted to somehow evacuate my mother, but I couldn't even contact her, and my heart sank.
Moreover, that sinkhole is clearly an abnormal symptom caused by the distortion of space and time.
I was more worried about the future, since something like this was already happening even though there was still time left.
'There is only one way left now.
We need to get Mia to Future Park as soon as possible.'
--- p.93

Yesterday, the ice cap of Mount Jungfrau melted and heavy rain poured down in Hungary.
Looking out the window, I saw that the train had already left the city.
There were dry trees with only branches left and cracked yellow earth spread out.
Next to it, the river, almost bare, looked like a stream.
There was not a single trace of winter left.

--- p.131

“I have a question.
There's someone after Mia.
Last time I said there were traces of illegal time travel.
“Could it be that person?”
--- p.133

The man passed Riho and trudged towards me, who was shivering in the hallway.
Contrary to my thoughts that I should run away, my feet did not move.
But there was one strange thing.
The face of the man who had just gotten out of the car with difficulty was so smooth.
Yesterday, Eun-sil scratched her forehead on the mountain train, but there was not a single scratch on her face.
“I found it, Lee Seo-rim.”
--- p.155

I looked around at the people left in the room and shouted.
"Does anyone have any water? If I have water, I can open that door."
Please help me.
I need to go back to Korea quickly and save my mom.
Only I can do that.
please……."
--- p.164

“That’s… just a temporary side effect.
He said that small sacrifices are inevitable for great success.”
That's what the director always said.
"What on earth is big and what is small? Is there anything in this world worth sacrificing?"
