Into the book
The reasoning motor in my head started whirring.
His eyes moved quickly behind his thick glasses.
Textbooks, folded school papers, crumpled east, west, south, north, and the dried grass because the lid was missing… … .
'Godong-oh secretly folds colored paper or plays with glue during class.' But now is not the time to be speculating about such things.
--- p.16
'Who drew that?' Among them, Cheon Jae-min's curiosity burned the brightest.
'Deduction' is Cheon Jae-min's favorite game.
How could a sparrow just pass by a mill? A detective can't miss an interesting case.
--- p.20
There was a magic wand-shaped sticker stuck on it.
My friends giggled.
Only the teacher stared at the desk with a serious expression.
Not only did you secretly doodle, but you even put stickers on it. That's too much.
I thought I absolutely had to find out who it was.
But my gaze gradually turned towards the tip of the magic wand.
--- p.34
Cheon Jae-min was nervous that people would find out that he had put up the stickers.
I hate being in the spotlight.
--- p.41
“Eww!” Hong Jae-woo screamed again.
Only then did everyone look at Hong Jae-woo.
One side of Hong Jae-woo's pants was soaked white with milk.
Hong Jae-woo put the milk carton down on the floor.
Then he stopped as he was putting the fallen milk cartons back up one by one.
“There’s half of this left.
Who drank less milk and just put it in!”
--- p.45
When the milk carton was opened, crucial evidence was discovered.
‘Could that be?’ A faint pink tint was sprinkled on the opening of the milk carton.
It's a trace of lip balm! 'The friend who applied lip balm today is the culprit!'
--- p.59
Cheon Jae-min walked confidently to his locker.
I went straight to the criminal's locker and put the magic wand sticker on it right away.
Then he leisurely returned to his seat.
--- p.61
In the quiet hallway, only the sound of Jaemin Cheon's footsteps echoed.
As I entered the men's restroom, I saw toilet paper balls stuck all over the place.
I rolled up a piece of toilet paper, soaked it in water, and threw it away.
There were three toilet paper balls: one on the ceiling, one on the sink mirror, and one inside the bathroom stall.
Judging by the height, the culprit must be pretty good at throwing the ball.
--- p.75
But Cheon Jae-min thought.
Clearing someone's grievance is definitely a worthwhile endeavor.
I felt a surge of pride in having done the right thing.
Cheon Jae-min put one hand in his pocket and fiddled with the remaining stickers.
I especially liked the rough texture.
'There's still one left.
'When will I use it?' Cheon Jae-min soon became lost in his own thoughts.
His eyes moved quickly behind his thick glasses.

Publisher's Review
'I wish no one knew I was a detective!'
The arrival of a completely new detective character, Cheon Jae-min!
If I had to pick the most inconspicuous child in class 1, grade 2, it would definitely be the main character, Cheon Jae-min.
Because I sit all day reading books, wear only colorless clothes, and rarely speak.
But in reality, Cheon Jae-min is working as a 'detective' who secretly solves minor but suspicious classroom incidents.
Unlike other detectives who flaunt their presence by wearing flashy coats and shouting, “You are the culprit!”, Cheon Jae-min hates standing out so much that he is busy keeping his identity hidden.
One question arises here.
'How does Cheon Jae-min uncover the culprit without coming forward?' The answer lies in the childishly-shaped 'magic wand sticker.'
It is about sticking a sticker on a crucial clue or criminal that you have discovered after intense reasoning and letting others know about it.
Additionally, Cheon Jae-min is a unique character in that he does not have a reliable assistant to help him or a notebook in which he can record events at any time.
This is because all the clues are organized one by one thanks to the so-called 'reasoning motor' in the head.
In this way, Cheon Jae-min deviates from the typical mystery fairy tale character, and because of this, all events flow in a more unpredictable and interesting direction.
Meet the quiet yet righteous new detective character, Cheon Jae-min, through "Sticker Detective Cheon Jae-min"!
A 100% realistic classroom fairy tale written by an elementary school teacher!
Minor but suspicious incidents that naturally draw you in.
The setting of the work, 'Class 1, Grade 2', is so similar to a real classroom that it can be considered ordinary.
But if you look closely inside, you will find a constant stream of suspicious incidents.
What is noteworthy is that it is so 'trivial' that you might not even think of it as an incident if you are not conscious of it.
Like a doodle written on a desk.
But even in things we can easily overlook, there's always a culprit! "Sticker Detective Cheon Jae-min" delves into that point in a playful way.
The incidents that frequently appear in the mystery genre are often overly extreme or difficult to encounter in everyday life.
That's why sometimes I have a hard time fully immersing myself.
However, "Sticker Detective Cheon Jae-min" increases immersion by dealing with things that actually happened or could happen in the classroom, written by an author who works as an elementary school teacher.
Thanks to this, young readers can enjoy the work more while thinking about their class.
As it shows how the same classroom scenery every day can instantly transform into a stage for a mystery full of twists and turns, children who read "Sticker Detective Cheon Jae-min" will have the special experience of loving the classroom even more than before.
A story about 'growth' and 'communication' learned through reasoning
Although he started out as a detective simply because he liked observation and reasoning, as time passed, Cheon Jae-min realized that clearing other people's names is a valuable job.
Cheon Jae-min, who had his own distinct world and never even tried to understand other children, learns how to communicate with his friends while solving cases.
《Sticker Detective Cheon Jae-min》 may seem like a light mystery story, but it is also a work that deeply explores Cheon Jae-min's growth period.
'Deduction' is a field that requires careful observation.
If you are indifferent to your surroundings, you cannot do true reasoning.
That's why the mystery genre not only provides entertainment, but also teaches us how important it is to have a mindset to understand and help others.
The children in the review group who read "Sticker Detective Cheon Jae-min" first left reviews saying, "I want to become a problem solver who solves big and small problems around me," "I want to feel the satisfaction of a detective by clearing other people's grievances," and "I want to be a friend like Cheon Jae-min who carefully observes his surroundings and helps people."
In this way, "Sticker Detective Cheon Jae-min" will remain a work that goes beyond being a fun story and conveys positive values to many children for a long time.
An honest recommendation from the children's book review group!
My dream is to be a detective.
Like Cheon Jae-min, I also want to be a friend who helps people by observing their surroundings carefully.
_1st grade Lee Yoon-chan
Jaemin's reasoning was cool, and it was more fun than other mystery detective books! _Park Da-eun, 1st grade
Cheon Jae-min is really smart and seems like a genius.
In our class, too, we threw away the milk without drinking it all, so the teacher told us to stand up, but no one stood up.
If Cheon Jae-min had been in our class, I think we would have caught the culprit.
_2nd grade Kim Yuna
The story of Cheon Jae-min finding the culprit is so exciting and fun that I can't put the book down.
It's so funny how they solve cases by sticking stickers on the magic wand that don't match the genius! _Han Ji-hoon, 2nd grade
It was amazing and cool that Cheon Jae-min helped the teacher solve minor issues.
I too want to feel the satisfaction of a detective by clearing other people's names.
_3rd grade Jeong Se-yeon
It was a fun read because it was about common school life events that weren't boring.
Author, is there going to be a second volume?! _Kim Seo-ho, 3rd grade
