You know how there are certain people you should never mess with in life?

For example...

A mobster's son.

Specifically, the kind of mobster's son where dozens of henchmen bow their heads and call him "Young Master."

The problem is... I realized this fact twenty years too late.

"Hey, Jo Minseong! Are you crying again? Crybaby! Look at the crybaby!"

Poke.

I was the one who shoved an earthworm in his face and made him wail.

I was the one who dragged him up a tall tree because he was scared, then climbed down alone when I heard it was dinner time, leaving him crying up there.

I was the one who hand-washed the sheets after he peed himself watching a horror movie, only to tease him about it for years.

I was the one who suggested exchanging chocolates for Valentine's Day, only to completely forget about it myself.

I was the one who talked him into skipping school, got caught climbing the wall, and immediately betrayed him by running away alone.

Every time, I'd buy him vanilla ice cream and apologize to the sniffling boy, but...

That was never going to be enough for an indulgence.

Because... His father.

He wasn't just an ordinary office worker; he was a Mob Boss leading a massive organization.

I had no idea what Minseong's father did for a living. I only knew his parents were busy; I never heard a single word about their work.

To me, his father was just a kind-looking uncle who gave me generous pocket money whenever we met...

Since he always smiled and handed me cash during holidays or whenever we crossed paths, I actually liked him quite a bit as a kid.

But now, to me, Jo Minseong isn't just my crybaby childhood friend anymore—he's the son of a mob boss whom I've made cry dozens of times. Shit.

Realizing this recently, I really wanted to kill my past self. I couldn't have been a worse villain if I tried.

. . .

There's no choice. I'm sorry, you bastard Jo Minseong. In the end, I'm sprinting away from my childhood friend again today.
