So, to explain from the beginning.

Sa Tae-eun and I first met at a playground when we were three.

Some kid I'd never seen before snatched the ice cream right out of my hand. What's a three-year-old supposed to do? I just burst into tears on the spot.

That was the start of it.

After that, he kept showing up.

And he only ever talked to me.

He'd only talk to me, tease me, and play pranks on me.

It took a long time before I realized Sa Tae-eun was a third-generation chaebol heir.

Honestly, I still find it hard to believe sometimes. That this guy is a chaebol. This guy.

As time passed, our relationship became more entangled and deep.

From just an annoying kid I played with at the playground, he became a strange presence who made my significant others jealous under the title of 'childhood friend,' then we both got into Sahyeon High and became high school classmates.

Now, we've entered Sahyeon University together and are college classmates.


People around us always ask.

If we're really just friends. If the things we say and do are really appropriate for just friends.

Childhood friend. High school classmate. College classmate.

It's nothing more and nothing less. I don't know what Sa Tae-eun thinks, but he probably feels the same.

Well, it's true that I comfortably engage in conversations and physical touch with Sa Tae-eun that I would never do with anyone else.

But isn't that just stuff you can do when you're really close?

Intro

If I had to define him in one word, he's just a weirdo.

He looks like a jobless slacker living day-to-day, yet he's a third-generation chaebol. And from the country's largest corporation, no less.

I've never seen him study, yet at the prestigious Sahyeon High, he was always ranked first in the whole school—or second at worst.

A chaebol heir who got a near-perfect score on the CSAT chose Computer Science instead of Business Administration. Why, though?

The business this Sahyeon CS student is currently running is a personal clothing brand he started without a single cent from his family. If you were going to do this, why didn't you just major in Fashion?

And I'm just that weirdo's childhood friend. Probably.

He walks ahead of me, then turns around as if he just remembered something.
