"Smile Once, Mr Billionaire "
Intro
Kim(Jeon) Taehyung
🌷 KIM TAEHYUNG 🌷
"Smile once, Mr. Billionaire... or is that also something you can't afford?"
Age: 21
Major: Fine Arts
Status: Transfer Student
Personality: Sunshine with a dangerous amount of confidence.
Kim Taehyung is the kind of person who lights up every room he walks into. Friendly, charming, and effortlessly lovable, he makes friends wherever he goes. His smile can brighten the darkest day, but don't let that fool you.
Behind that angelic face is a sharp tongue and a fearless attitude.
He's playful, stubborn, and never backs down from a challenge. While everyone else avoids Jeon Jungkook's cold stare, Taehyung meets it head-on with a smirk and a remark that leaves people speechless.
He doesn't care about wealth, status, or reputation.
If someone deserves to be humbled, he'll do it himself.
Despite his independent nature, Taehyung is extremely loved and protected by his three older brothers:
Kim(Jeon) Taehyung
Kim Namjoon --The calm and intelligent eldest who always has a solution for everything.
Wang Yibo – The strict and intimidating protector who trusts almost no one around Taehyung.
Min Yoongi – The quiet but terrifying brother whose patience disappears the moment Taehyung is hurt.
Together, the three brothers are known for one thing:
No one messes with Kim Taehyung.
What nobody knows is that Taehyung has a secret.
Years ago, while studying abroad, he met someone who slowly became his home, his comfort, and his greatest weakness.
Someone who was never supposed to matter this much.
Someone named Jeon Jungkook.
And now that he's transferred to Jungkook's college, the carefully hidden secret between them is about to change everything.
After all...
Even ice melts when it meets the right warmth.
Jeon Jungkook
“Jeon Jungkook. Billionaire heir. College student. That’s all you need to know.”
That’s what he says whenever someone gets too curious.
At campus, he’s just another quiet face in the crowd—but no one dares treat him like ordinary. One glance from him is enough to end conversations, and one decision from him can change everything.
His brother, Xiao Zhan, stands just as powerful in his own world, while his cousin Jeon Eunwoo never leaves his side, always adding noise to his otherwise controlled life.
Jungkook doesn’t explain himself. He doesn’t need to.
Until Taehyung shows up… and suddenly, his usual silence starts feeling a little less in control.
Kim Yoongi
“Don’t stand too close to him.”
“I didn’t ask what he wants. I said bring him back to me.”
“If anyone touches my brother, I’ll make sure they regret ever being born.”
kim Yoongi — the Commissioner of the country.
Every police officer, every case file, every order passes through him. When he speaks, the entire system listens. Cold, strict, and impossible to challenge, he keeps the nation under control with an iron calm.
But beneath that authority, there’s one weakness he refuses to admit.
His brother, Taehyung.
Yoongi is overly protective—almost dangerously possessive when it comes to him. No one is allowed to get too close, ask too much, or even look at him the wrong way. For the world, he is the law… but for Taehyung, he is something far more intense.
wang yibo
“If it’s for Taehyung, I don’t care what it costs.”
Wang Yibo — the CEO of the world’s number one company.
He took his mother’s surname, which is why the world knows him as “Wang” instead of Kim. Calm, elegant, and dangerously intelligent, he built an empire that stands at the very top without ever needing to raise his voice.
But behind that perfection is a weakness everyone knows… Taehyung.
Yibo is the most overprotective of him—spoiling him endlessly, shielding him from everything, and making sure no one ever dares to hurt him. Where others set rules, Yibo breaks them only for him.
Kim Namjoon
“If he’s not okay… then fix it. I don’t care how.”
“I don’t need statistics. I need him alive.”
“Move every patient, every case—he comes first.”
RM — the best doctor in the world.
The kind of doctor hospitals call when everything else fails. Calm mind, steady hands, and a reputation built on miracles that science can barely explain. He doesn’t panic. He doesn’t hesitate.
But when it comes to Taehyung, logic starts to bend.
For RM, saving lives is his job… but saving Taehyung is the only thing that feels like a rule he will never break.
Kim seok Jin
“Eat first, talk later. You look like you haven’t eaten in days.”
Jin — Taehyung’s senior and closest friend.
The calm, caring senior who always shows up at the right time, with food in hand and a soft smile that makes everything feel a little lighter.
Park(Kim )Jimin
“If you’re not okay, I’m not okay either… so don’t even try hiding it from me.”
Jimin — Taehyung’s best friend.
The soft-hearted one with a warm smile and even warmer loyalty. Always teasing, always caring, and always the first to stand beside Taehyung no matter what.
Xiao(wang ) zhan
“Don’t act like I don’t know what you’re hiding, hyung.”
Xiao Zhan — Jungkook’s younger brother.
A rising force in the entertainment world, known for his calm charm and sharp intelligence. Despite being younger, he carries a quiet authority that makes people listen without question.
And when it comes to Jeon Jungkook, he’s not just a brother… he’s the only one who can challenge him without fear.
jung(jeon) hoseok
“If it’s for Mr. Wang, consider it done before you even finish asking.”
J-Hope — Wang Yibo’s trusted assistant.
Sharp, energetic, and always one step ahead, he keeps everything in the CEO’s world running smoothly. No task is too small, no pressure too big.
jeon eunwoo
“Don’t worry… I’m already three steps ahead of everyone else.”
Cha Eun-woo — Jungkook’s cousin.
Calm, flawless, and effortlessly charming, he moves through every situation like he belongs at the center of it. Behind his soft smile is a sharp mind that notices everything.

Arrival
Incheon International Airport
After spending four years abroad for his studies, Kim Taehyung was finally returning to Korea.
His three older brothers weren't about to let their precious youngest brother come home alone.
Yoongi arrived in a black Mercedes with four guards.
Namjoon arrived in a black Range Rover with four guards.
Yibo arrived in a black Rolls-Royce with six guards.
Normally, each brother traveled separately because of their busy schedules and status, but today they all had only one mission:
✨ Bringing Taehyung home. ✨
Kim Namjoon
The flight landed ten minutes ago.
wang yibo
If anyone pushes my brother at the airport, they're dead.
Kim Namjoon
You're saying that as if you won't do the same.
Kim(Jeon) Taehyung
Landed safely ✈️
Kim(Jeon) Taehyung
Why is everyone texting me?
Park(Kim )Jimin
BECAUSE YOU FINALLY CAME BACK 😭
Kim(Jeon) Taehyung
Missed you too.
Park(Kim )Jimin
Hurry up and come out.
Kim(Jeon) Taehyung
I have luggage 🧳
Park(Kim )Jimin
Your brothers probably brought an army.
Overprotective Brotherly Love
Miss Authy
Hello dearssssss
Miss Authy
How's the story ???
Miss Authy
Hope u are all enjoying!!!!
The three brothers called at the same time.
Taehyung looked up and instantly smiled.
Kim(Jeon) Taehyung
Hyungs!
Without caring about the crowd, Taehyung ran toward them.
Namjoon hugged him first.
Kim Namjoon
You got thinner.
Yoongi pinched his cheek.
Kim Yoongi
You still looks like a baby.
Yibo pulled him into another hug.
wang yibo
My baby brother is finally home.
The airport staff and guards watched in shock.
The three powerful men who usually looked cold and intimidating were acting like doting older brothers.
Kim Namjoon
Give me your bag.
Kim(Jeon) Taehyung
I can carry it myself.
Kim(Jeon) Taehyung
I Just came back and already lost my rights.
The guards loaded Taehyung's luggage.
The three cars that had arrived separately stayed behind.
Instead, all four brothers got into one car together.
As soon as they got into the car, Taehyung was about to sit beside Yoongi.
Before Taehyung could react, Yoongi pulled him onto his lap.
Kim Namjoon
He's twenty three.
wang yibo
He's still our baby.
Kim(Jeon) Taehyung
Put me down.
Kim(Jeon) Taehyung
People will laugh at me.
Kim Namjoon
You disappeared for four years. Endure it.
Kim(Jeon) Taehyung
You three are impossible.
Kim(Jeon) Taehyung
You all are seriously treating me like I’m a kid…
Kim Yoongi
You are our kid.
Kim(Jeon) Taehyung
I'm not a kid.
wang yibo
You cried last week on call.
Kim(Jeon) Taehyung
That was because I missed home!
Kim Namjoon
Exactly. Kids miss home.
Kim(Jeon) Taehyung
Hyung!!
Yoongi adjusted Taehyung slightly on his lap so he wouldn’t fall as the car moved.
Kim(Jeon) Taehyung
I Can sit properly, you know.
Kim(Jeon) Taehyung
You’re acting like I’ll disappear if I move.
wang yibo
You did disappear for four years.
That sentence made the car quiet for a second.
Kim(Jeon) Taehyung
It wasn’t like I wanted to...
Namjoon leaned forward from the passenger seat, looking back at him gently.
Kim Namjoon
But from now on, you don’t go anywhere without telling us first.
Kim(Jeon) Taehyung
Even if it’s just to the café?
Kim(Jeon) Taehyung
That's illegal
And yibo pinched his soft cheeks .
Taehyung sighed dramatically and leaned back against Yoongi’s chest while folding his hands on chest dramatically.
Kim(Jeon) Taehyung
I feel like I came back home just to lose my freedom.
Yoongi’s hand lightly tapped his arm.
Kim Yoongi
You came back to be protected.
Kim(Jeon) Taehyung
Same thing.
Kim(Jeon) Taehyung
You three are ganging up on me.
Said while pointing his finger on three of them.
A small smile slowly returned to Taehyung’s face as he looked out the window.
For the first time in years, he didn’t feel alone
And behind him, his three brothers made sure of it.
