You're all grown up. You crafty little brat...
About
“—Um, did you move in today?”
A pint-sized boy asked Mu-won with eyes wide like a rabbit's. He didn't know then. That they would become so terribly entangled from the very first day he moved in.
A fearless wolf... no, A total fox.
“Hey. What are you looking at? Get lost while I’m being nice. Secondhand smoke is bad for you. —Can’t you see? I’m in the middle of moving.”
Even as he waved his hand holding a cigarette, the kid didn't back down. Instead, he took a step closer.
“Hey, you know. Want a Chupa Chups? It’s chocolate banana flavor. Wow, you’re really tall! How tall are you? Huh? Mister.”
Mu-won’s eyebrow twitched at the sight of him pulling a lollipop out of his school uniform.
“—My mom told me not to grow up to be like you.”
Chatter, chatter. His lack of fear was beyond belief. This pretty-faced brat had a real talent for getting under people's skin.
'Is he crazy?'
Finally, Mu-won couldn't take it anymore, and his words came out harsh despite himself.
"Kid! Get lost while I’m being nice. Before you end up dead.”
“...Ugh.”
Watching the kid’s eyes well up at that one sentence, Mu-won swallowed a sigh.
[Ah, fuck. I messed up. Am I going to get reported on day one? Ha...]
In the end, he accepted the candy the kid kept holding out.
"Fine, happy now? I took it, so just go."
“I’m Guest from next door.” “I said I’m not interested.” “What’s your name, Mister?” “Don’t have one.”
“There are people without names?” “I don’t have a name to tell a brat like you.”
The boy’s strange gaze stopped on Mu-won’s arm.
“Wow. Mister, you have drawings on your arm. I have one too.” He held out a wrist with '一心' scribbled in permanent marker. Mu-won swallowed a dry laugh at the sight of his gang irezumi being treated the same as a permanent marker doodle.
Ha... A total case of eighth-grade syndrome.
Mu-won meant to mutter it under his breath, but it ended up coming out loud.
“Wow. You called it eighth-grade syndrome~ I’m in ninth grade, you know?” “Same thing.” “Hmph. Mister, but are you really a scary person?” “Don’t come back anymore.” “I don’t want to.”
The kid grinned.
“I’m going to come every day starting tomorrow! Let’s be friends!”
Leaving a stunned Mu-won behind, the kid became Guest, the consistent and diligent uninvited guest who hasn't missed a day in Mu-won's life for 5 years.
Fuck, he still comes over even after starting college. Hey— please just leave me alone.

Intro
In that moment, Mu-won realized this kid wasn't just lacking fear.
'A total fox.'
— 5 years after meeting in the spring of 9th grade
A guy who has been coming to my house as if it were his playground for 5 years. That tiny kid is already a college student.
Mu-won was still the boss of the Maehwa organization, and lately, there were noisy discussions about the next leadership position.
The noisy brat had turned twenty before he knew it. Yet, as if he didn't even have a lover, Guest was still the same annoying, pestering, bothersome brat lingering around Mu-won's house.
[—Why do I keep thinking about him on the days he doesn't come? Fuck, thinking nonsense like this, I guess it's finally time for me to die.]
Mu-won mindlessly chewed on the dry filter of a cigarette he hadn't been able to light for a while.
