Trauma Code: A Hero in Love
genre: workplace romance, comedy, mutual pinning, slow-burn, banter, suggestive
A series of one-shot stories between Dr. Baek Kang Hyuk (Ju Jihoon) and Dr. Song Hye Joo (Song Hyekyo)
When Dr. Baek’s former med school rival, Dr. Song Hyejoo, joins the trauma center team, his usual composure is shaken—just a little competitive, and maybe a little shy. As they face emergencies together, they learn to work in sync, and they rediscover something they never dared explore before.
This will be a series of one-shot stories between Dr. Baek Kang-hyuk and Dr. Song Hye-joo (my OC; played by Song Hyekyo, because why not. Also I badly need the casting directors to pair them for a romcom or melo drama together 👉🏻👈🏻).
It’s not a story where everything is in chronological order or a continuation of what happened to the previous chapters. It’s like a series of moments.
Might include a chapter with their backstory in university and when they met again after many years when Dr. Song is introduced as the new addition to the trauma center team before I upload a series of chapter moments between them ><
I tried to keep Dr. Baek Kang-hyuk’s character as similar and accurate as I can, but you know what, 🎀 I’m just a girl 🎀 who wants to see him be a little clumsy and shy around his (secret) crush. So if it’s a little inaccurate or if you think it’s out of character, then I’m so sorry asdfsghjkg ;—; but isn’t it fun to imagine the cool (sexy) hot-tempered doctor become a fool in love for someone? Like a total loser. Frankly it’s my favorite character trope. He’s all mean and scowly with other people, and then he absolutely melts and malfunctions when a beautiful, strong, and intelligent woman (a.k.a his long-time crush) comes near him.
Anyway, I hope you guys enjoy it!!🥹 I’ve already written A LOT of random chapters. And I might also include a little bit of nsfw, or maybe just suggestive, IDK I have no experience in writing sensual scenes, I feel like it’s gonna sound cringey when I do it wish me luck🥲👍🏻

Chaewoon’s protective instincts toward Haein become more apparent as he observes her every move with quiet care. His subtle gestures and watchful presence reveal a side of him that Haein begins to notice—one that goes beyond his role as a bodyguard.
It had been a week since Chaewoon became Haein’s bodyguard, and in that time, he’d already learned to read her like an open book. Watching her through the glass walls of her office, he could tell just by the way she furrowed her brows and gripped the paper tighter—something was bothering her.
Five, four, three, two, one... he counted in his head.
As expected, Haein’s sharp voice rang out, “What happened to decorating the personal shopper room like a gallery? The artist’s reputation and colors don’t suit the interior design.”
Chaewoon couldn’t help but smile. Yelling and glaring like that, she looks so mean.
But then, just as quickly, her expression shifted, a satisfied smile curling on her lips as she flipped to the next page. “Yes, this is what I was talking about.”
She looks excited, Chaewoon thought, still watching her every move.
The annoyed Haein from moments ago was gone, replaced by a woman pleased with what she saw. And just as Haein’s lips slightly curled up, Chaewoon’s own little smile started to falter. For a moment, time slowed down, and for some reason, he could not look away at her smiling face.
He cleared his throat, forcing himself to look away and stare blankly at the opposite wall, as if that would shake the strange, unsettling feeling that had taken hold of him.
------------------------------------------------------------------------------
HAEIN'S POV
Hong Haein wasn’t used to people caring about her—not in the way Woo Chaewoon did.
Not that she would ever admit it.
But for a while now, she had stopped trying to shake him off. That didn’t mean she liked his presence, but she had accepted, begrudgingly, that he was annoyingly efficient at his job.
She just hadn’t expected him to be so… considerate.
1. The Elevator Incident
It started in the company lobby. Haein was walking ahead, clicking through emails on her phone, when the elevator doors opened. She stepped in without thinking.
Then, in a single swift motion, Chaewoon reached out, placed a firm hand on the small of her back, and pulled her back just as a man rushed out, nearly knocking into her.
She barely had time to react before she found herself standing inches from him, her back against his chest.
“Watch your step,” he murmured, his hand falling away the second the man passed.
Haein straightened, clearing her throat. “I had it under control.”
Chaewoon didn’t argue, simply stepping inside after her. “Of course, ma’am.”
She turned to glare at him, only to find the faintest hint of amusement in his eyes.
Infuriating.
2. The Heels Problem
Later that day, she had back-to-back meetings, which meant strutting around the office in heels that looked good but felt like a medieval torture device.
By the time she stepped outside, her feet were killing her.
As they reached the car, Chaewoon—without a word—opened the door for her, then subtly adjusted the car mat so she could rest her feet more comfortably.
It was such a small gesture, so smooth, that she almost missed it.
She slid into the seat, watching as he walked around to the front. Inside the car was also a pair of soft comfy slippers that was not originally there.
Her jaw tightened. He wasn’t supposed to be like this. He was supposed to be just another disposable bodyguard, a shadow she could ignore.
Then why was he making it so difficult?
3. The Rain
By the time they arrived at a charity gala that evening, it had started raining. Hard.
As usual, Chaewoon was the first to step out of the car. He retrieved an umbrella, opened her door, and held it above her.
Haein, exhausted and mildly annoyed at the world, reached for the umbrella.
“I can hold it myself.”
Chaewoon, as always, was unmoved. “That’s my job.”
She stepped out, expecting him to keep a respectable distance. Instead, he adjusted the umbrella so that she was completely covered—even if it meant part of his shoulder got drenched.
She noticed. And she hated that she noticed.
By the time they entered the building, she found herself stealing glances at his wet sleeve.
Chaewoon brought her a towel, his expression as calm as ever. She expected him to use it to dry himself off, but instead, he held it out to her.
She raised an eyebrow, about to refuse, when he paused for a brief moment. Then, with surprising grace, he knelt down in front of her, positioning the towel to wipe her shoes.
Oh, my shoes are wet.
The realization hit her like a bolt of lightning. Haein instinctively stepped back just as his hand was about to touch the leather.
“You don’t need to do that. You’re not my servant,” she said, her tone sharper than she intended. She cleared her throat, trying to regain some composure. “Wipe yourself instead. You’re drenched.”
She huffed, a bit embarrassed by the sudden awkwardness, and turned on her heel, walking briskly into the gala without looking back.
------------------------------------------------------------------------------
CHAEWOON'S POV
The Elevator
Woo Chaewoon was always quick on his feet. So, when Haein, her attention absorbed by her phone, failed to notice the man about to collide with her as the elevator doors opened, he reacted instinctively.
Chaewoon's reflexes kicked in without thinking. His hand moved swiftly to the small of her back, steadying her just as a man rushed out, too close for comfort.
For a brief moment, he felt her back tense against his chest as he pulled her away. The contact surprisingly electric, but he didn’t let it show. He barely heard her breath catch in her throat, but he noticed.
"Watch your step," he murmured quietly, making sure the man passed safely before letting his hand fall away from her back.
She straightened up quickly, her back stiff. He could feel the subtle shift in her posture as she composed herself.
“I had it under control,” she said, voice a little sharp, but he didn’t respond to the challenge in her tone.
Instead, he stepped into the elevator after her, keeping his face unreadable. “Of course, ma’am.”
She turned to glare at him, her eyes narrowing in irritation. But for just a moment, he caught the faintest flicker of something else there—amusement, maybe. It was gone too quickly for him to dwell on, but it made him smile to himself, just the slightest curve of his lips.
Infuriating. But somehow, she made it worth it.
2. The Heels
Chaewoon had learned to notice the small signs that Haein never acknowledged. He could see it in the way she walked—stiff, her heels clicking sharply against the floor as if she were fighting the discomfort that no one else seemed to notice. Her back straightened, her pace measured, but there was always that subtle shift in her posture after each long meeting. The heels, he knew, were not made for comfort. He also knew she would never be the type to wear flats outside.
So, when they reached the car after a long day, Chaewoon opened the door for her without a word, then quickly adjusted the car mat under her feet. It wasn’t much, just enough to give her a bit of relief, and he did it so smoothly that she almost didn’t catch it.
But she did.
As she slid into the car, he caught the slight wince in her face, then the subtle relief as she settled into the seat. Chaewoon walked around to the front, but when he opened the door to slide in, he saw her eyes lingering on the pair of slippers he had neatly placed inside for her.
Her gaze was confused, almost questioning.
It was an ordinary thing, a small act of care, but it was enough for him to see the slight stiffening in her jaw. He couldn’t help but wonder why she was so resistant to the simplest gestures. After all, he was only doing his job. But still, the thought lingered. She wasn’t supposed to be this difficult to ignore.
Yet, here she was, making it harder than it should be.
3. The Rain
Chaewoon didn’t expect her to notice. The rain had soaked through part of his sleeve, but it wasn’t the first time, and it wouldn’t be the last. He held the umbrella steady over her, making sure not a single drop touched her, while the cold slowly seeped into his own shoulder. It wasn’t anything out of the ordinary. It was his job.
But then, she looked.
It was quick, just a glance at his wet sleeve, but he caught it. The slight pause in her step, the way her gaze lingered a fraction too long before she looked away. She noticed. He wasn’t sure why that detail mattered, but for some reason, it did.
By the time they reached the entrance, she was back to her usual self—sharp, composed, untouchable. But Chaewoon had seen the flicker of something else. He returned with a towel, expecting her to take it without a second thought. Instead, she hesitated.
So he did what came naturally—knelt down in front of her.
Her shoes were wet. He had noticed, of course, just as he noticed the slight shift in her stance, the way she tensed the second she realized what he was about to do. Then, before he could even move, she stepped back.
“You don’t need to do that. You’re not my servant.” Her voice was clipped, but it wasn’t anger. It was something else—something that made her avert her gaze a second too late.
Chaewoon didn’t argue. He simply stood, towel still in hand, watching as she walked away quicker than usual, like she was trying to escape something.
As she walked further ahead, Chaewoon’s eyes followed her. His gaze lingered just a moment longer, catching the flush of her ears—redder than usual.
He wondered if it was the cold, or if it was something else entirely.
------------------------------------------------------------------------------
It was another busy day for Hong Haein, this time at Queen’s Department Store. She was making her way through the floors when a commotion near the cosmetics section caught her attention. A small crowd had gathered, murmuring among themselves as an angry man raised his voice at one of the employees.
At first, Haein didn’t interfere, simply observing from a distance.
The customer was demanding a refund for a product that was nearly used up. The employee, a young woman, remained professional, explaining that refunds weren’t possible once the product was almost empty. But the man wasn’t listening. Instead, he insisted—loudly—that his girlfriend’s skin had worsened because of it. A blatant lie. It was a common trick—buy, use, complain, and demand a refund.
But then, the situation escalated.
Frustrated by the refusal, the man swiped an arm across the counter, knocking over bottles and compacts. The sharp sound of breaking glass made the employee flinch.
“Do you think I’m some kind of joke?” His voice rose, and so did his hand.
Chaewoon, standing silently nearby, was already prepared to intervene. But before he could move, Haein was already stepping in.
She caught the man’s wrist mid-air, stopping his hand before it could strike the employee.
“And who the hell are you?!” he snapped, yanking his arm back. His face twisted in outrage, as if personally offended that a woman had dared to stop him.
Haein’s expression remained calm, her voice unwavering. “This is not a place for such behavior.”
The man scoffed. “Then bring me your CEO. I don’t have time for people like you.”
“You’re looking for me?”
His face faltered for a second before he recovered. “So you’re the CEO?” He sneered, folding his arms. “Figures. No wonder your employees are incompetent. Why did you not train your employee properly then!?”
“You’re right,” she said coolly. “Maybe I haven’t trained them properly.” She turned to the employee, glancing at the nametag. “Ms. Kim Minji?”
The young woman tensed, clearly expecting a reprimand.
Haein sighed and crossed her arms. “Your job is to deal with customers only. As for criminals, report them to the police immediately.”
The man’s face reddened. “Wow. A criminal? So now you’re insulting customers? The CEO of this mall looks down on people. We will sue you.”
Haein simply smiled. Behind her, Chaewoon observed the scene with quiet amusement.
“Please do,” she said lightly. “I’ll be suing as well.”
The man sputtered. “What did you just say?!”
His temper snapped. His hand moved again, this time toward Haein.
But before he could get close, a shadow loomed over him.
Chaewoon was already there.
His tall frame blocked the man completely, cutting off his path like an immovable wall. His movements were smooth, effortless, but his presence alone was enough to make the air feel heavier. In one swift motion, his hand wrapped around the man’s wrist—not rough, not violent, but firm. A controlled grip, precise and unyielding.
The shift in atmosphere was instant.
The man’s anger wavered, his bravado shrinking under the weight of Chaewoon’s presence. Up close, he could see the way Chaewoon carried himself—not just as an employee, not just as security, but as someone who was dangerous in all the ways that mattered. There was no unnecessary aggression in his stance, no tension in his shoulders, no wild anger in his eyes. Just cold, calculated control. The kind that made people second-guess their next move.
For the first time since the commotion started, the man hesitated.
Chaewoon’s grip didn’t tighten, but the unspoken message was clear: Don’t try it.
The man swallowed. His wrist, though not in pain, felt like it was caught in something unshakable. He looked around, as if realizing how quiet the crowd had gone, how the eyes that once watched in amusement were now filled with anticipation—waiting to see if he would be foolish enough to push further.
He wasn’t.
“You can be charged with obstruction of business, property damage, and attempted assault,” Chaewoon said evenly. His voice wasn’t loud, but it didn’t need to be. It carried the kind of weight that made people listen.
Haein tilted her head, unfazed. “And I’ll add another lawsuit for the sales loss you caused.” She turned to the crowd. “Did you all get that on camera?”
A chorus of affirmations rose from the spectators, many holding up their phones, their screens still recording. A few even cheered.
The man looked around, suddenly realizing how outnumbered he was.
“Take them to the police,” Haein ordered as security finally arrived, stepping forward to apprehend him.
As the man was dragged away, Haein turned back to Chaewoon, a satisfied smile on her face. He met her gaze, his own expression unreadable.
She gave him a small nod. “Let’s go.”
Without another word, Chaewoon followed.
On their way back to the company, Haein found herself replaying the moment in her head.
It had happened so fast. One second, she was handling the situation as she always did—calm, composed, in control. The next, a hand had been raised in her direction, and before she could even react, a shadow had stepped in front of her.
Chaewoon.
Haein had barely registered the movement before he was there, his tall frame blocking her completely. The space that had once felt open was suddenly filled—broad shoulders, solid stance, the subtle shift of muscle beneath his suit.
She hadn’t been expecting it.
She had seen him be cautious before, seen the way he silently observed her surroundings. But this was different.
His hand had wrapped around the man’s wrist—not roughly, not aggressively, but with a kind of controlled force that left no room for argument.
She hadn’t seen his face at first, only the sharp line of his jaw from the side, the way his fingers flexed slightly as if calculating the exact amount of strength needed to hold back without breaking.
Then she had seen the change in the man’s expression. The way his anger faltered, the realization creeping in. He had thought he could intimidate her, but now he was faced with someone he couldn’t push, someone who didn’t even need to raise his voice to make his presence known.
“You can be charged with obstruction of business, property damage, and attempted assault,” Chaewoon had said, his voice low, even. It wasn’t loud, but it carried the kind of weight that made people listen.
Chaewoon didn’t move, his stance unwavering, his hand still gripping the man’s wrist as he watched him with cool detachment. And for the first time, Haein realized something.
For all the quiet patience she had seen in Woo Chaewoon, there was another side to him. A side that wouldn’t hesitate to shield her the moment someone dared to lay a hand on her.
And for reasons she couldn’t quite place, she found herself staring at him just a moment longer than necessary.
Gentle, quiet, patient Woo Chaewoon. You had this side to you, huh?
The thought followed her into the car. As they drove in silence, she caught a glimpse of him through the rearview mirror. He looked the same as always—calm, focused, completely unbothered.
She clicked her tongue and turned to the window, blinking more times than necessary.
As if that would make her stop thinking about it.
From the front seat, Chaewoon felt Haein’s gaze linger on him. He kept his eyes on the road, but he noticed everything—the slight shift in her seat, the way she suddenly blinked faster before turning to the window.
For a brief moment, he felt… aware of himself. Just a little.
But why?
Why did her gaze make him falter, even for a second?
He didn’t know.
