Chapter1: Butterfly with a Hidden Blade
Dahran: YN... YN! Wake up! It's already late, you're gonna miss your lecture.
YN: Ugh, Dahran... it's 8:30! You were supposed to wake me up at six.
POV: Meet YN — the second daughter of Mr. Lee, a powerful businessman deeply connected with Seoul's mafia. He claims to love her, but treats her no better than a servant.
YN resents this. She's proud, cold, and untouchable.
People call her heartless — but beneath the surface, she's fragile, like a butterfly that longs to fly free.
Her mother disappeared when YN was just 4. Everyone believes she's dead — everyone but YN.
Dahran, their loyal housekeeper, raised her.
Now, at 20, YN is stunning, stubborn... and secretly searching for the truth.
Dahran: Don't blame me, young lady. I came to wake you up — but your soul was somewhere else.
YN: Whatever. I'm awake now.
YN gets up and walks into the bathroom to freshen up. A few minutes later, she comes downstairs, ready to head out.
Just as she opens the door, Dahran steps in front of her.
Dahran: You're not leaving without breakfast. Sit.
YN: I'll eat out later, okay? I'm running late.
Dahran: You're not eating again? Should I tell your father you've been skipping meals?
YN: Ugh, fine! I'll eat.
She sits down and eats quickly while Dahran stands nearby, watching her like a hawk. As soon as she finishes, YN grabs her bag and rushes to the door.
YN (smirking): Even if I ran away, you'd never say it — but I know you love me. Bye!
She laughs and darts out the door.
Dahran (smiling softly): This girl will drive me crazy...
📚 At the University
YN: Shit... I'm late. Class must be ending by now.
YN is only allowed to attend this one university — and even that was a battle. Dahran had to convince her father after months of arguing. Why?
Because YN loves business and fashion design, and she's determined to be more than just a mafia heir's daughter.
She finally makes it to class and knocks on the door.
YN: Good morning, sir. May I come in?
Professor: No. Class is already over.
YN: I'm so sorry — the traffic was horrible today.
Professor: Funny. None of your classmates saw any traffic. Just you.
YN (thinking): Ugh, this man is such a pain. I swear, one day I'll be free from all this.
Professor: Did you say something?
YN: No, sir.
As the students start leaving, her best friend Zara shows up.
Zara: YN! You okay?
YN: I'm fine. You?
Zara: Same. Hey, wanna come over today? My family's busy and I could use some company.
YN: Umm... but my dad—
Zara: I'll talk to him. Just say yes!
YN: Alright. Let's go.
🏠 Zara's House
Zara is the younger sister of a mafia kingpin, but unlike her cold-blooded family, she's cheerful and full of jokes. She's 21 and fiercely independent.
When they arrive at her house, YN flops down on the living room couch.
YN: Ugh, I'm so tired.
Zara: I'm starving.
Chapter 2: The Stranger in the Room
YN: Zara! Why are there men's clothes in this room? These aren't yours!
?: That's because they're mine.
As she turned, YN's eyes widened.
A man was inside the room — not just any man, but one who had a woman with him, doing things she should have never seen.
She gasped, her face pale with shock. The man stared back at her, surprised, but amused.
She didn't wait.
YN screamed, stumbled toward the bathroom, then ran the opposite way. In her panic, she bumped her head on the wardrobe and ended up crying, breathless, until she found the kitchen.
Taehyung's POV:
I was in my room. The girl I brought over was still undressing when suddenly — the door opened.
A different girl walked in.
She wore only a thin robe and panties.
She froze. I froze.
And then she panicked. Ran out.
Didn't even wait to hear me.
She was beautiful — but fragile, like a deer caught in headlights.
So soft. So breakable.
The girl I was with looked confused. I told her to leave.
I needed to know who that was.
Back in the Kitchen
Zara rushed to YN, worried.
Zara: YN! What happened?!
YN: I–I... I saw something!
Zara: What? Who?
YN: That guy… I saw everything!
Just then, Taehyung came downstairs, his shirt now on. The woman he was with was already gone.
YN pointed, whispering:
YN: Him. It was him.
The fear on her face was clear. She didn't even want to look him in the eye.
Zara (angrily): I told you not to come here without telling me first!
Taehyung (calmly): The house was empty. I thought I'd stop by.
Besides, I'm hungry. Got anything ready?
Zara: I'll get you something light. YN, come help me—
YN: No, thank you. I should go home. It's already late.
Zara: But—
YN: Maybe next time. Bye.
She rushed out, covering her robe with her scarf again. She didn't look back.
Taehyung's POV:
She walked away...
I usually hunt my prey.
But this one walked straight into my room.
She's sweet... innocent...
That body, though? Dangerous.
I won't forget her face.
Zara: Stop staring. I know what you're thinking. But she's 31 — too old for your games.
Taehyung: Age is just a number. Why was she so shaken up?
Zara: Because she's never seen anything like that before.
Taehyung (grinning): Then it's a good thing I'm the first.
Zara: Yeah, but maybe not while you're with another woman…
Taehyung (curious): So... you think she wants me?
Zara: I hope she does. She's my best friend. I want her to be my sister-in-law someday.
She's soft, kind... smells like fresh roses. No one else compares to her.
Even her kisses must be—
Taehyung (jealous): Stop! Have you kissed her?
Zara (laughing): Relax! We're best friends. We hug, we tease... I even beg for kisses sometimes.
Taehyung: She's mine now. Don't say that again.
He slammed his hand on the table. Zara flinched.
Zara: Okay okay, calm down.
Damn… jealous already, huh?
No wonder they call me "Kim Zara the Chaos Queen."
🕯️ That Night...
YN couldn't sleep.
She tossed and turned in her bed, the scene from earlier haunting her mind.
Suddenly, her phone rang.
YN: Hello?
?: Can't sleep, princess? Or… are you thinking about me?
YN: You?
Taehyung: Recognize my voice, don't you?
YN: Ugh… leave me alone, devil. I barely saw you. Why would I remember?
Taehyung: Oh, you will. I promise.
She hung up instantly, heart pounding.
She pulled her blanket tighter around her and whispered to herself:
YN: Who the hell is this man?
