Chapter 6 - Childhood Echoes and the Cabin Confrontation

The sleek luxury sports car cut smoothly through the crowded evening traffic of Seoul, its cabin wrapped in a bizarre, layered blanket of silent friction and casual conversation. In the front seats, CEO Choi Sun-woo and Ma Ha-rin sat shoulder-to-shoulder, maintaining absolute, freezing silence as they deliberately ignored one another, staring straight ahead at the asphalt. In contrast, the rearview mirror painted a completely different picture. Sun-woo and Kim Seo-ah were chatting smoothly back and forth, their professional tones relaxing into a comfortable flow.Sun-woo adjusted his grip on the leather steering wheel, subtly glancing toward the rearview mirror to catch Seo-ah's reflection. "By the way, Miss Kim, where exactly are we headed this evening? What is our final destination?"Seo-ah adjusted her coat over her lap, offering a polite smile. "We need to go straight to the university hospital, Sir."Sun-woo's corporate curiosity sparked instantly, his mind remembering his brother's panicked phone calls. "The university hospital? Why? Is someone close to you currently admitted or handling medical treatment there?""Yes, Sir," Seo-ah nodded, leaning forward slightly as she prepared to clarify the situation. "Actually, my—""Wait a single minute!" Ha-rin suddenly interrupted, her dramatic voice cutting through the vehicle space like a sharp blade. She threw her hands in the air, spinning around in her passenger seat to glare between the two of them. "Can't someone on this floor actually talk to me too?! Seriously, you two just keep talking on and on and on without a single pause! I am literally sitting right here in the front seat!"Sun-woo's executive composure completely cracked for a fraction of a second. He shot a strict, piercing glare directly sideways at Ma Ha-rin's profile, his jaw tightening as an angry groan echoed inside his thoughts. 'Couldn't this stubborn girl have waited just a little while longer before opening her mouth?' Sun-woo thought, his internal frustration mounting. 'Kim Seo-ah was literally just about to reveal the absolute identity of the mysterious patient!'Ha-rin didn't back down. She turned her head sharply, locking eyes with Sun-woo with a defiant pout. "What exactly is the matter, Sir? Why on earth are you staring at me with such a heavy, strict look?"Sun-woo immediately forced his eyes back onto the road, his tone turning clinical and icy. "Nothing at all, Ma Ha-rin."Seo-ah leaned back against the leather cushions, letting out a heavy, thoroughly embarrassed sigh as she nudged her roommate's seat from behind. "Ha-rin, please! Can't you just stay completely quiet and mannered for once in your life?""Fine! If that's how it is, from now on, absolutely no one speaks inside this vehicle—is that perfectly okay with you, Sir?!" Ha-rin huffed, crossing her arms tightly over her designer handbag.Sun-woo made a subtle, thoroughly amused face, clicking his tongue as he navigated the lane. "Yes, that will be completely fine with me.""Ha," Ha-rin let out a sharp, cynical scoff. Nodding her head stubbornly, she turned her face entirely away, staring out of the passenger car window at the passing neon lights of the Seoul streets.Sun-woo's eyes drifted back toward her reflection in the side glass. He continued to quietly watch her quiet, pouting profile for a few silent moments, a strange wave of deep, unyielding familiarity touching his chest before he focused back on the traffic ahead.A short while later, the luxury sports car pulled up smoothly along the grand, glowing entrance curb of the International Daehan University Hospital. The engine purred to a stop under the evening sky.The doors clicked open, and Kim Seo-ah and Ma Ha-rin stepped out onto the cool pavement, gathering their shopping bags. Sun-woo unbuckled his seatbelt, shutting his door firmly as he stepped out right after them, smoothing down his charcoal tailored suit jacket.Seo-ah turned around, bowing politely to the sharp CEO. "Thank you so much for the premium lift, Sir. We appreciate your kindness. We're heading straight inside the building complex now."Sun-woo adjusted his cuffs, his posture radiating calm executive authority as he walked step-for-step beside them. "Yes, I understand. I'm coming inside the hospital lines too."Ha-rin stopped dead in her tracks on the pavement, her eyes widening in pure suspicion as she rounded on him. "Why? Why are you coming inside?"Sun-woo stopped right in front of her, raising a cool, calm eyebrow. "Why? Am I legally or professionally not allowed to step inside a public medical facility, Ma Ha-rin?""It's absolutely not about that, Sir..." Ha-rin whined, wrinkling her forehead in deep annoyance. "But why on earth are you constantly following our steps today? We are fully capable of walking inside on our own."Seo-ah felt a cold sweat of mortification hitting her neck. She frantic-style grabbed her roommate's shoulder, pulling her back forcefully. "Wait, Ma Ha-rin! Stop being so incredibly rude! Let him speak properly—let him explain why he needs to come inside the complex.""Exactly! Thank you, Miss Kim," Sun-woo countered smoothly, shooting Ha-rin a triumphant, deadpan look. "I am absolutely not following you, Ma Ha-rin. The truth is, I happen to have a very close personal friend working here at this branch, and I want to go up and see his office floor. So, please, don't flatter your personal ego too much."Ha-rin's face turned a bright shade of pink. She huffed loudly, spinning back toward the sliding glass doors. "Fine! Whatever! Come on, Kim, let's move."The two girls hurriedly marched inside the grand hospital lobby first, leaving Sun-woo standing alone on the concrete pavement.Sun-woo stood entirely still for a second, watching her retreating figure with a soft, incredibly warm sigh. A quiet laugh escaped his lips as a sudden wave of vivid childhood memories flooded his thoughts."Hah..." Sun-woo murmured to himself, his eyes glowing under the twilight. "She really hasn't changed a single bit. Even back in our childhood playground days, she used to act exactly like this whenever I arrived."[FLASHBACK: EXT. NEIGHBORHOOD PLAYGROUND – YEARS AGO]The bright afternoon sun lit up the dusty sandbox of the neighborhood park. A group of local kids were running around, laughing and playing tags—including a young, neat-uniformed Kim Seo-ah and a tiny, fierce Ma Ha-rin building structures in the sand.Suddenly, two young brothers stepped onto the playground layout. A young adult Choi Sun-woo, looking sharp even as a teenager, walked with firm strides, while a young Choi Hyun-woo trailed eagerly beside him. Hyun-woo's eyes lit up the microsecond he spotted Kim Seo-ah. He ran straight across the grass, approaching her sand pile with a blushing, eager face."Hey! Hi!" Little Hyun-woo blurted out, clutching his backpack straps. "What exactly are you doing down there?"Little Ma Ha-rin instantly stood up from the sandbox, wiping her dusty hands on her skirt as a thoroughly annoyed, protective expression crossed her tiny features. "Oh, look—you two unknown boys showed up again? Why are you constantly following her steps around every single afternoon?! And you won't even tell us your real name! It's so weird!"She spun around, glaring up at the tall, quiet Sun-woo standing right behind his brother's shoulder. "And you... does this little lackey of yours always have to be glued strictly to your side everywhere you march?!"Young Sun-woo crossed his arms, his intense eyes narrowing as his protective brotherly pride flared up against the fierce little girl. "What exactly is your problem, you loud brat? You are her little lackey yourself, aren't you? Why are you shouting at us?"An aggressive, hilarious childhood argument instantly broke out between the two sides, their small voices filling the quiet playground.Young Hyun-woo completely ignored the bickering, keeping his hopeful eyes locked on Kim Seo-ah. "I will explicitly tell you my real name only if you agree to be my best friend first!"Little Kim Seo-ah stood up, crossing her arms stubbornly as she shook her head. "Stop following me! I don't want to be friends with an anonymous stranger. Come on, Rin—that's completely enough debating now."She grabbed Ha-rin's tiny hand firmly and started to walk away toward the park exit gates.Little Ma Ha-rin turned her head back over her shoulder, sticking her tongue out as she shouted out childish nicknames at the top of her lungs. "Yeah, let's go, Seu! Goodbye, Mr. Anonymous and Mr. Lackey!"[FLASHBACK ENDS]Back in the present day, Sun-woo let out another soft, nostalgic laugh as the memory faded. He shook his head with deep affection. "Oh, that stubborn girl..."He adjusted his suit jacket and walked firmly past the sliding glass doors, heading inside the grand hospital complex to trace his brother's location.[INT. International Daehan University Hospital – Ward – CONTINUOUS]Inside the orthopedic room, the atmosphere was calm. Kim Do-jung—Junu—was resting comfortably against his pillows when the door clicked open. Kim Seo-ah and Ma Ha-rin walked straight inside the room, setting their shopping bags onto the side table.Seo-ah rushed over to the bedside chair, her face full of concern. "Hi, Junu! How exactly are you feeling right now? Are you okay?"Junu shifted his cast-bound leg, letting out a playful, sarcastic chuckle as he looked at them. "Oh, so you two finally managed to make it to my room? I thought you forgot about me entirely."Ha-rin rolled her eyes playfully, dumping her purse on the counter. "No, actually, we are still completely at home resting on the sofa. This is just a holographic projection."Junu groaned, throwing his hands up. "Can't you ever give a single straight, serious answer to a normal casual question, Ma Ha-rin?"Seo-ah ignored their banter, leaning closer to inspect his chart board. "Are you truly okay, Junu? Did Dr. Hyun-woo tell you anything specific during his morning rounds? Do you know the absolute date when you'll finally be discharged from this ward?"The moment the doctor's name was mentioned, Junu's expression turned thoroughly puzzled and serious. "No, he didn't tell me a single professional thing about my discharge. In fact... his medical behavior has been really, exceptionally strange for the past two days."Ha-rin tilted her head, her gossip instincts sparking instantly. "What?! Strange behavior? How exactly? What did he do?"Seo-ah's brow furrowed in deep concern. "Is he bothering you or neglecting your treatment line, Junu?""No, it's absolutely nothing professional like that," Junu explained, shaking his head in confusion. "He's just been calling me by my full, real last name 'Mr. Jung' with this incredibly rigid, fake smile for the last two days. And then, he randomly leaned in and asked me how exactly I know you in real life! I tried to explicitly explain everything to him, but before I could even say a single line, he got violently angry, shouted at me to shut up, and just walked away into the hall! All of this bizarre tension started right after the microsecond he met your face. Is there something romantic or hidden going on between the two of you?"Seo-ah felt a sudden, burning wave of heat hit her cheeks. She hesitated frantically, her eyes darting away as she tried to cook up an excuse. "No... noway, Junu! I literally met his face for the very first time right here at the hospital ward. Just completely ignore his strange attitude. It's nothing."Junu narrowed his eyes, studying her nervous expression. "Yeah, okay... but you are telling me the absolute truth, right, sis? If there is any kind of trouble or harassment from the staff, please let me know immediately."Seo-ah swallowed hard, her voice shaking slightly as she lied. "No... everything is perfectly stable."Standing near the beverage counter, Ha-rin watched her friend's burning red cheeks, and the puzzle pieces instantly clicked together inside her sharp mind. 'Oh! Now I finally get the whole picture!' Ha-rin thought to herself, a triumphant smirk breaking across her lips. 'That handsome doctor is completely, entirely jealous! Could there be a massive, hilarious misunderstanding regarding Junu being her boyfriend?!'Ha-rin quickly stepped forward, grabbing her handbag with a smooth movement. "Kim, I'm just going to go step out and see Dr. Hyun-woo in his office for a brief moment."Seo-ah blinked, startled. "Why on earth do you need to see him?""Just to formally ask about the medical timeline of when Junu will finally be discharged, of course," Ha-rin winked playfully, her eyes full of hidden mischief.Seo-ah shot her a highly warning, gesturing glance. "Okay, fine... go ahead, but please don't mess anything up or create a scene, alright?""Got it perfectly," Ha-rin giggled, turning on her heel and slipping out of the ward door smoothly.Junu looked at his sister, thoroughly confused. "Why on earth did you say that to her?"Seo-ah let out a soft sigh, sitting back. "Oh, just because. You know exactly how chaotic her personality is, right?""Yeah, fair enough," Junu laughed, adjusting his blanket.Meanwhile, out in the busy medical corridor, CEO Choi Sun-woo was marching down the hallway, searching for his brother's office wing. He stopped beside a passing head nurse, offering a polite corporate nod.Sun-woo: "Excuse me."Nurse: (Bowing respectfully, taking in his sharp suit) "Yes, Sir? Do you need any assistance or help navigating the floors?"Sun-woo: "Yes, could you please tell me where exactly is Dr. Choi Hyun-woo's private office located?"Nurse: "Ah, Dr. Hyun-woo is currently inside his private break room office at the end of this corridor on the left, Sir."Sun-woo: "Alright, thank you very much."The nurse bowed and left the aisle. Sun-woo walked firmly down the quiet hallway, approaching the heavy wooden panel marked with his brother's name. He raised his hand, knocking firmly once before opening the door just a fraction.Sun-woo: "May I come inside, Doctor?"Dr. Hyun-woo was seated heavily in his executive desk chair, massaging his temples in a state of absolute stress. Without looking up, he murmured, "Yes, come in."Sun-woo stepped inside the luxurious private room, shutting the heavy door firmly behind his build. The second Hyun-woo raised his eyes and spotted his older billionaire brother standing inside his office, he stood up from his chair in absolute, paralyzing surprise.Dr. Hyun-woo: (Lowering his voice rapidly into a calm but frantic whisper) "Sun-woo?! How on earth are you here right now on my hospital floor?!"Sun-woo: (Walking over, leaning casually against the desk frame) "Actually... I came down to this complex directly with my future sister-in-law, Kim Seo-ah. I drove her here."Dr. Hyun-woo: (His face turning pale as he panicked softly, gripping his desk) "WHAT?! You drove her here?! Don't tell me you explicitly told her that we are sige brothers?! Why on earth did you do that?! You have completely ruined my entire romantic plan!"Sun-woo: (Raising a hand, his tone perfectly calm and executive) "Calm down, you idiot. I didn't tell her a single word about our family empire. Just relax and take a breath."Dr. Hyun-woo: (Letting out a massive sigh of relief, sinking back into his chair) "Even so... why on earth did you come all the way inside my office wing?"Sun-woo: (Crossing his arms, looking thoroughly annoyed) "Well... I honestly thought that by driving them here and coming inside the ward, I'd easily find out the absolute identity of who her mysterious boyfriend is. But... I failed completely, all because of that chaotic Ma Ha-rin interrupting the conversation every single second."Dr. Hyun-woo: (Wrinkling his forehead, looking thoroughly confused) "Yeah... I am stuck in the exact same loop, bro. I can't figure it out. Is that patient Junu her brother? Or is he actually her romantic boyfriend?"Right at that exact microsecond of deep fraternal deliberation, the quiet sound of fast footsteps echoed directly outside the private hallway corridor. Ma Ha-rin approached the heavy wooden panel of Dr. Hyun's private cabin. She raised her hand, knocking firmly on the wood panel.Ma Ha-rin: (From behind the door, her cheerful voice carrying clearly through the wood) "May I come inside, Dr. Hyun?"Inside the room, Sun-woo's eyes widened to the size of saucers. He turned his head sharply toward the door panel. "That voice sounds incredibly familiar... Yes, it is absolutely Ma Ha-rin."Hyun-woo's heart skipped a panicked beat. He gestured frantically, whispering softly through his teeth, "Is she here?! Oh my god, you need to stay completely quiet and hide right now!"Sun-woo: (Whispering back fiercely, his executive calm shattering as he scrambled) "Okay! Fine! But where on earth am I supposed to hide in this small room?!"Outside the threshold, Ma Ha-rin stood waiting, tilting her head as the silence stretched over the wood panel. She muttered to herself under her breath, 'Dr. Hyun isn't saying a single thing to answer my knock... Is he perhaps not inside his office floor right now? Should I just take the risk, open the door, and check the room inside myself?'Driven by her natural stubborn curiosity, Ma Ha-rin firmly turned the metallic handle and stepped straight inside the private executive cabin...
