Author's Note

What if you had to kiss someone before their seventeenth birthday?
What if you were given a one-way ticket to Mars?
Want to be friends with AI?
What if today were repeated every day?
What if you had to continue studying on a ruined Earth?

"Kiss Virus" begins with Yuna's mom and dad urging her to kiss quickly as her seventeenth birthday approaches.
Even when I go to school, all I hear is stories about kissing.
In particular, high school sophomores who received TAT shots (cold vaccines) immediately after birth, like Yuna, are called to the counseling room on the first day of their birthday month to receive guidance on whether or not they kissed, even if it was indirectly.
This is all due to the kissing virus. The virus, which penetrates through the TAT vaccine, reacts with the growth hormone that begins to be secreted at the age of 17, causing abnormal behavior.
The abnormal behavior is that on a rainy day, they laugh like crazy without realizing it and run around in the rain. At that time, the children infected with the virus display an unknown strength, making it completely impossible to control them.
Yuna tries to find various ways to kiss to avoid this disaster.
Will Yuna's kiss be successful?

In "Going to Mars," Seonbin, who is the envy of all her friends, appears.
Because I don't have to worry about college entrance exams, military service, or even getting a job.
Seonbin, who had never been lucky in the lottery, was hit with the luck of a lifetime.
Selected as the representative Martian immigrant of South Korea in the Martian Project MARS-X.
However, the biggest obstacle for Seonbin preparing to immigrate is her father.
This is because they strongly oppose Seonbin's trip to Hwaseong, where he is leaving for a place without family or friends, with no hope of returning.
Seonbin, torn between a secure future and an uncertain Earth with loved ones, will he be able to board the spaceship to Mars safely?

"Repair No. 7" is the story of Repair No. 7, a classroom assistant robot introduced to Yeonju and Yeonju's class in the first year of middle school.
Yeonju, who was in the same class as Jaehee, who had bullied her since elementary school, has a hard time making friends and is always alone.
To the lonely Yeonju, the touch of Repair No. 7 feels warmer than that of the other human children.
Yeon-ju, who was discovering the joy of school life thanks to Suri 7, gets hurt by Suri 7, who only acts according to the manual, contrary to her own feelings... Will Yeon-ju and Suri 7 be able to share their feelings?

Beomjun from "Perfect Today" is very worried because he has to tell his parents by today about the rude prank he played on his logic teacher with his classmates the day before.
But all the kids in the class who were playing together are as if nothing happened yesterday.
And surprisingly, the same thing happened in logic class yesterday.
Beomjun thinks that yesterday's events were a very vivid dream, but the next day, and the day after that, and every day, the same days repeat themselves.
But no one believes Beomjun's words.
Even the transfer student who knew this fact like Beomjun starts to change like other kids one day... Will Beomjun be able to escape today, which has no exit?

As the title suggests, "The Last Classroom" is set in a classroom built on a planet that has been turned into ruins after a nuclear power plant exploded in a major earthquake.
In preparation for Earth's catastrophic conditions, twenty countries around the world have built classrooms deep underground.
It is our belief that ‘education’ is what can revive the Earth when it becomes a ruin.
So, the students who are preserved as models from each country gathered there must receive an education from their own country until they can go out again, and pass it on to their descendants.
Seoyoon is a child who came to this classroom by mistake.
This was the place where Kim Seo-yoon, a model student with the same name and surname as her from the same school, should have come.
Seoyoon, who has no choice but to live by the rules here, has more than one or two suspicious things.
What good is studying in this situation? Is the outside world really dangerous?
What choice will Seo-yoon make in the end as she searches for a way out with other children from other countries who share the same thoughts?

The main character of "Will You Save the Earth?", Jae-in, is ostracized by the whole school after being mistaken for having a crush on her friend's boyfriend.
But one day, a woman appears to Jaein and tells him something strange: that she has been chosen as the Earth Extension Decider.
The woman is the Asia Regional Team Leader of the Earth Life Decision Center, 'Soid.' According to her, whenever there was apocalyptic speculation, 99 people from around the world, randomly selected by the Earth Life Decision Center, would vote on whether or not to extend life on Earth, and this time, Jaein was selected as one of the 99.
Transfer student Yumi appears in front of Jae-in, who is in trouble after receiving a plastic card with an OX mark on it.
Yumi approaches Jaein, who is bullied by all the students, without hesitation.
How can Yumi help Jaein with his struggles as he contemplates whether to extend or end life on Earth?

“I realized that each and every one of us is the planet Earth itself.”
This Earth is extremely harsh for the children in these six works.
Infected with the kissing virus, the future on Earth is so uncertain that you'd jump for joy as if you were going to Mars, you don't have a single friend to share your school life with, every day is the same, and you survive on Earth after a nuclear power plant exploded in a great earthquake, but you're stuck at school with nothing to do but study, and you're ostracized by your friends because of misunderstandings.
However, the crisis and distress that has befallen these children are by no means created by them.
The Earth they live on just rotates like that.


Here, the choice is entirely up to the children.
In each work, children look deeply into their own situations and think deeply about them.
The situation he is in is by no means easy, so on the one hand he wants to avoid it, but he does not run away easily.
One thing is certain: children's choices are directed towards the Earth.
The situation of children, where things go a little strangely and things go wrong unintentionally, is similar to the Earth, which does not roll as I want it to.
The children in each novel do not turn away from it, but jump in and embrace it with their whole bodies.
When readers see such children, they will also feel a sudden desire to lean towards them and hug them.

Author Kim Hye-jeong says, “Becoming an adult means having to make your own choices.”
It is said that by “making your own ‘choices’ at the crossroads of life and creating your own life,” you prepare to become an adult.
So, what the author hopes for young readers through this book is to “think together, asking, ‘What if I were you?’”
