This is a story about the main character Jae-won's busy daily life as he struggles to make money, and thinking about what is truly important.
Lim Ji-hyung, the author of this fairy tale, advises, “The super-rich, or truly rich, are not just people with a lot of money, but people who know what is precious to them.”
Children who read this book will also have the opportunity to think about what is precious to them and what kind of person a truly super-rich person is.

“If you study hard, you can earn a lot of money.
Have you ever seen someone who didn't study well and still makes a lot of money? So, you should study hard!”
This is like a song my mom sings whenever she sees me.
Especially when a new semester starts, they do it day and night, as if it were a 'special nagging event'.
As time went on, it got stuck to my ears like a tag.
'It was all about money!'

'Hehehehe.
Then, errands cost 1,000 won, trashing is a bit dirty, so 1,500 won, and giving a massage... ... Okay, let's charge 1,000 won for this too.'
Laughter kept leaking out of my mouth.
As I was putting a price on it, it seemed like I would make a lot of money right away.
My heart swelled in an instant.
I felt like putting it into action right away.

I started massaging the slightly angry grandmother's shoulders.
I rubbed my grandmother's shoulders with all my heart, just like I would rub my grandmother's shoulders.
Then, the grandmother forgot about her previous outburst and spoke in a gentle voice.
“Oh my, oh my! It’s refreshing.
“No, why are little children’s hands so rough?”
Only then did I, who had been anxious, feel relieved.
At least one service passed.

“It’s really weird. Whenever I ask him to hang out, he always says he’s busy.
“You’re so annoying these days.”
Yongjun also grumbled as if he had been holding back for a while.
Come to think of it, I haven't really had a chance to properly hang out with Seok-Hoon and Yong-Jun since I said I was going to make money.
But now, I couldn't do what Yongjun and Seokhun wanted.
“Sorry! I’ll pay you back later.”
“What do you mean, pay it back? If you can’t play, you’re out.
“Let’s go, Yongjun!”
Seok-Hoon laughed and went outside with Yong-Jun.

After my grandmother left, I saw my hand holding the money.
'Hehehe.
'I finally earned 20,000 won.'
It was on a whole different level from the five thousand won I earned last time.
Holding two ten-thousand won bills in my hand, I felt like I owned the world.
'Uh-huh.
'Money is a good thing, after all.'
It was really good.
I thought I knew why my mom kept saying money, money, money.
When I had money in my hands, it seemed like there was nothing to fear or envy in the world.
So I guess I have to earn a lot of money.
"You're doing great, Lee Jae-won! Keep going."

Seok-Hoon got angry and pulled my arm away.
Tears were already streaming down both cheeks.
"what's the matter"
“I don’t need any of that.
“Get out of here.”
Seok-Hoon shouted as before and started running.
I finally caught it, but it kept running away, so I just had to let it be.
But somehow I can't just stay still today
There wasn't any.
I had a feeling that if I just stayed like this, my relationship with Seok-Hoon would grow further apart.
