Previously, the tension between Kim Dan and Joo Jaekyung intensified as their complicated relationship deepened. Heesung’s growing interest in Dan sparks jealousy in Jaekyung, while Dan struggles with his feelings. Jaekyung’s possessiveness becomes clearer as Jaekyung prepares for a match, emotions and secrets surface. After his victory, a new crisis threatens their fragile bond, raising questions about loyalty and love in Jinx Chapter 41-50!
Jinx Chapter 41: Incoming Birthday…

Dan’s morning started with a visit to his grandmother. He handed her a small bag of souvenirs, which she adored. As always, she spoke fondly of Jaekyung, praising his strength, his dedication, and his supposed good manners. Dan listened with a weak smile, thinking of the real Jaekyung; impatient, sharp-tongued, impossible. Still, even as he left the hospital and sat on the bench outside, he couldn’t shake the thoughts in his head. Jaekyung had taken up space in Dan’s mind. Dan stared at the sky, sighing to himself, certain now that he’d caught feelings. How could he fall for someone so blunt and difficult? But then, wasn’t it also the same fire in Jaekyung that pulled him in? Dan knew it would be a headache. He just hadn’t expected to fall this hard. Later at home, Dan quietly prepared lunch. He stole glances at Jaekyung, admiring his face. Caught staring, Jaekyung looked up and asked if he had something to say, his tone as curt as ever. Dan, flustered, changed the subject, asking about the ongoing investigation. He still couldn’t recall what happened that night, the memories stagnant in his mind.
Fractured Fight
That evening, while Jaekyung trained at the gym, fans from overseas flooded the place with gifts. It was Jaekyung’s nightmare: posing for photos, pretending to care about things he didn’t. The coach reminded him of next month’s fight, but the tension in Jaekyung’s shoulder was obvious. Sparring wasn’t going well, and Dan rushed to take him to the therapy room. His hands moved gently, trying to check the injury, trying to care, but Jaekyung pushed him away with his usual temper. His birthday was coming up, and he wanted to do something for Jaekyung. But more than that, he wanted to know how someone with a shoulder like that could survive the ring, ending Jinx Chapter 41.
Jinx Chapter 42: Disposable

Dan stared at Jaekyung’s medical reports. The shoulder was worse than he imagined. Fighting in this state was dangerous. What more could he do? Glancing at his phone, he noticed the date. Jaekyung’s birthday was just days away. Maybe something small could lift his spirits. Later that day, Dan roamed Jaekyung’s home, searching for something that could hint at a gift he might replace or improve. But everything was polished and luxurious. Dan swallowed hard, realizing just how little he had in comparison. Everything in the house was flawless, except for one thing. His gaze fell on a worn-out leather keychain, the edges frayed with time. That, Dan thought, is something he can replace. Determined, he began picking up late-night delivery jobs. The gift wasn’t cheap. So he roamed through the city night after night, fatigue building in his limbs. After one such shift, he returned home at dawn, cooked breakfast for Jaekyung as usual, and collapsed on the kitchen counter in exhaustion.
Ghosts That Never Left
At the rehabilitation center that afternoon, the doctor’s words hit harder than any punch. If Jaekyung fought in his current condition, he might need surgery. That could end everything. Night came again, and Dan resumed deliveries. He was nearly done; just one more left. He rang the bell and the door opened. A man stood there, familiar in a way that made Dan’s stomach drop. It was him—the man from the past, Jaekyung’s former lover. Recognition flickered between them like static, and then the man smiled. “You’re nothing special”, he said. Jaekyung always discards people when he’s done. Dan stood frozen, heart pounding, as the door closed in his face, ending Jinx Chapter 42.
Jinx Chapter 43: Slipping Edges

Dan couldn’t shake the man’s words, no matter how much he tried. You’re nothing special. The phrase looped in his mind on the way home. In his daze, he didn’t notice the rock in his path until he tripped, falling hard from his bicycle. Blood smeared across his knees and palms, but he barely winced. Maybe the man was right. Maybe all he ever was to Jaekyung was a tool: convenient, disposable. The next day at the rehab center, Dan’s hand trembled slightly as he worked on Jaekyung’s shoulder. He misjudged the pressure and dug in too hard, causing a streak of blood to stain his forearm. It stung, but Dan simply stepped away, ignoring the pain. Jaekyung noticed that his gaze lingered longer than usual. Still, Dan brushed it off, cleaned the wound in silence, and skipped dinner again. He was used to breaks that never felt like rest.
A Night of Mistaken Glasses
The long-awaited birthday gift finally arrived the next morning. It wasn’t as flashy as the others that would surely come Jaekyung’s way, but Dan had chosen it with care. That afternoon, the gym was filled with excitement and celebration. Jaekyung allowed himself a rare moment of enjoyment. They all went out for beef and drinks, the atmosphere warm and chaotic. Dan, cautious, tried to limit his alcohol, discreetly passing a full shot into a nearby glass to pace himself. What he didn’t realize was that the glass belonged to Jaekyung. When Jaekyung took a sip, he froze. He never drinks. But now, the damage was done. Annoyed and already a little buzzed, the alcohol hit him fast. The party eventually died down, and everyone filtered out. Dan walked ahead into the night, only to feel an arm wrap around his shoulder. He turned to see Jaekyung, drunk and leaning on him without a word. Dan sighed, choosing to take him home. And with that, Jinx chapter 43 comes to an end.
Jinx Chapter 44: A Quiet Collapse

The door clicked shut behind them as Dan guided Jaekyung into the apartment. The air inside was heavy. Jaekyung stumbled forward, eyes half-lidded, hair tousled from the night. His usual sharp edges were softened by the haze of alcohol, his mood uncharacteristically tender. He clung to Dan like a sulky cat, muttering under his breath, swaying with each step. Dan carefully helped him sit on the edge of the bed, crouching to remove his shoes. As he looked up, he was met with a sudden tug, Jaekyung pulling him close, arms loosely wrapping around his neck. It wasn’t forceful or demanding. He allowed Dan to kiss him. No resistance. No sharp words. Just a rare silence.
They didn’t say much after that. Their movements were slow, searching, more about closeness than desire. Jaekyung’s hands found the curve of Dan’s back; Dan buried his face against Jaekyung’s shoulder, the steady thrum of his heartbeat loud in the quiet room. Curled together under the sheets, tangled limbs and breath shared in the hush of the night. Dan held him like something fragile. And for once, Jaekyung didn’t pull away. Will Jaekyung remember this in the morning? Will his soft side clash with his hard demeanor? With numerous unanswered questions, Jinx Chapter 44 ends.
Jinx Chapter 45: Jerk Jaekyung

Morning light filtered through the windows as Jaekyung slowly woke to a headache. He dragged himself up and opened the door to find a mountain of birthday gifts. Lavish boxes from fans and sponsors were piled high, unwanted. Behind him, Dan stirred from sleep, the warmth of last night still clinging to him. Dan got up slowly, watching Jaekyung with concern. He noticed the color drained from his face. Dan walked up and asked softly if he was okay. Jaekyung muttered something under his breath. His head hurt. His whole body did. He turned and went to the kitchen, quietly preparing a bowl of soup. As Jaekyung sat down to eat, Dan reached into his bag and pulled out the small box he had been waiting to give. He placed it carefully on the table and spoke with hesitation, choosing his words slowly. He told Jaekyung it was a small birthday gift he had worked hard for.
More Than Just a Gift
Jaekyung opened the box with a careless motion, his expression hardening the moment he saw the keychain inside. He scoffed, clearly unimpressed, and turned on Dan with irritation, questioning why he had wasted time on something so pointless. Dan stood frozen, unable to speak for a moment as the weight of disappointment settled in his chest. He had worked so hard to give Jaekyung something meaningful. All he wanted was to show a bit of gratitude, maybe even get close enough to say what he truly felt. But instead of understanding, Jaekyung’s reaction was cold and sharp. Without warning, he grabbed the keychain and hurled it across the room. It struck the wall and fell to the floor with a dull sound that echoed louder than it should have. Dan lowered his head, biting his lip as embarrassment flushed through him. He had hoped for warmth, but now, silence was all that answered. With a heavy heart, Jinx chapter 45 concludes.
Jinx Chapter 46: Just a Body, Never a Name

Dan sat on the floor of the empty kitchen, arms wrapped around his knees, his face buried against them as silent tears soaked through the fabric of his pants. His chest ached, not from physical pain but from the slow, heavy realization sinking in. It had always been one-sided. Jaekyung had never seen him as anything more than a convenience, a body to ease stress, a pair of hands to tape his shoulder, a quiet presence that never talked back. He remembered the way Jaekyung would leave after their nights together without a word, the way he would walk past Dan in public like he didn’t exist, never offering even the smallest kindness. Once, Jaekyung had even made Dan pick up his gear in front of the team, treating him like a personal servant while others laughed or looked away. Every small humiliation, every cold glance, is now stitched together into something undeniable. Dan had never mattered.
Betting on Blood
On the other side of the city, Jaekyung was spiraling. He was short-tempered with his coach, dismissive with teammates, snapping at anyone who dared speak to him. His usual discipline and cool control were gone, replaced by violence. Reputation no longer concerned him. There were whispers in the gym now, people calling him unhinged, reckless. What was worse, rumors had begun to circulate outside. A betting pool had opened up around the upcoming match, not just on the fight itself, but on whether Jaekyung would even make it through without losing his cool or collapsing from injury. The tension in the gym was thick. No one dared confront him, not when he moved like a bomb waiting to go off. But something seems off. There are files of Kim Dan all over the man’s desk and lots of pictures. What can go wrong now? Is Jaekyung’s reputation hanging by a thread?
Jinx Chapter 47: Everything All at Once

The atmosphere at the gym shifted the moment news broke. Jaekyung’s original opponent had fractured his leg during a sparring session, just weeks before the match. Excitement buzzed through the building until the replacement name was announced. Baek Jumin. A rising MMA fighter with no recorded background, no public interviews, and no footage worth studying. Just brutal results in the ring and a reputation for being unhinged. Even the coaches looked uneasy. No one knew how he fought, only that he didn’t hold back.
And worst of all, he didn’t respect rules or reputations. Jaekyung might have been dominant, but Baek Jumin? He was a wild card, and that made him dangerous. Later that evening, Dan went home, exhausted in every sense of the word. Since Jaekyung’s birthday, he hadn’t exchanged a single word with him. Dan had enough to carry already. His grandmother’s biopsy results were coming in the next morning, and the weight of that reality was heavier than anything Jaekyung had ever thrown at him.
Goodbye That Matters
The next day arrived like a storm. The doctor’s words were careful, but the message was clear: the medicine wasn’t working. The cancer was not shrinking. Dan stood frozen outside the hospital, tears welling up as the weight of it all pressed against his chest. He didn’t even notice his phone ringing in his pocket, the screen flashing with an unknown number. None of that mattered. Not right now. Dan made his way to his grandmother’s bedside, his eyes red, voice barely steady. She smiled at him, weak but warm. As she rested, Dan sat beside her, flashes of their life together rushing through his mind. The one person who had never made him feel small, who had carried him through every storm of his life, was fading before him. And he could do nothing about it, ending Jinx Chapter 47.
Jinx Chapter 48: Lines That Shouldn’t Cross

Dan stepped out of the hospital into the heavy air of late afternoon, his thoughts still clouded with the weight of his grandmother’s condition. He barely had time to gather himself before someone called his name. Standing a few feet away was Choi Gilseok, the manager of King of MMA Gym, Baek Jumin’s manager. Dan’s body tensed instantly. He tried to walk past him without engaging, but Choi wasn’t the type to be ignored.
With a casual step forward, he pressed into Dan’s space, even striking a nerve, mentioning his grandmother, her illness, and how money could change everything. Choi offered him double his current salary, even promising access to better treatment, all in exchange for one thing: information on Jaekyung: his training routine, his weak points, his approach in the ring. Dan’s gut turned. The offer was tempting, but his answer was clear. No. He turned away and left.
The Cost of Doubt
That night, Dan sat at the computer, trying to distract himself. He didn’t want to betray Jaekyung, even if Jaekyung never saw him as more than a tool. Still, something pulled at his chest. Maybe it was guilt, maybe fear, or maybe just the weight of everything crashing in at once. Eventually, Dan stepped out of his room and moved quietly through the apartment. He found Jaekyung in the living room, eyes locked on the screen, studying footage of Baek Jumin with intense focus. Dan hesitated, unsure if he should say anything. Just as he turned to leave, Jaekyung’s phone buzzed with a message. His eyes narrowed as he opened it, and a series of photos filled the screen, images of Dan, outside the hospital, speaking to Choi Gilseok. The atmosphere shifted instantly, sharp and cold. Dan hadn’t said a word yet. But someone else already had, concluding Jinx Chapter 48.
Jinx Chapter 49: Spy

The stadium roared as the match finally began. Joo Jaekyung and Baek Jumin stood face to face in the ring, their glares sharp enough to cut through the tension. Cameras flashed, fans screamed, but neither man moved. Their focus was absolute. A flashback slipped in, just a day earlier, in a quiet hallway between training rooms. The two coaches passed each other, and Baek Jumin casually raised a hand in greeting.
Jaekyung met him without expression, until Baek Jumin stepped in closer, lowering his voice to whisper something only Jaekyung could hear. Whatever it was, it hit hard. Jaekyung’s eyes had widened with a rare mix of rage and disbelief. Hours later, as he sat alone in the bath, the words echoed in his head. taunts from his past. Loser Jaekyung. Baek Jumin knew things he shouldn’t. Jaekyung clenched his jaw. He should have taken Jumin down long ago. But now? He wouldn’t lose.
Underhanded Games
The next day, as Jaekyung trained harder than ever, Choi Gilseok entered the gym. He walked in without warning, his presence throwing off the rhythm of the room. His words were subtle, but laced with venom, poking at Jaekyung’s pride until Jaekyung nearly snapped. As chaos stirred between the two, no one noticed the brief moment of interference, an unnoticed switch. The relief spray bottle, normally placed beside the mats, had been swapped out with something else. Training resumed once the tension died down, but Jaekyung’s body moved more slowly, stiffer. His foot twisted mid-step, and he winced. Dan rushed to grab the spray. He pressed the nozzle onto his feet, and pain lit up his skin instantly. A sharp, burning sting spread across his feet, turning red and raw. This wasn’t the usual spray. Something was wrong.
Jinx Chapter 50: Grave Mistake

The atmosphere in the locker room was thick with tension, but it wasn’t because of the upcoming fight; it was because of Dan. The team was furious. The relief spray incident had alarmed everyone, and Jaekyung’s injury was now more serious than anyone had anticipated. Dan and Yoon Gu had checked the spray together, and something must have been switched without their knowledge, but no one seemed to care. Jaekyung refused to even look at him. When Dan stepped forward to help wrap his foot, Jaekyung pulled away violently and stormed toward the medical staff instead. There was no trust left in his eyes, only fury. Dan stood helpless. The distance between them had never felt so sharp.
Bloody Fight
Jaekyung entered the ring wearing an ankle guard, his steps measured and tense. Across from him stood Baek Jumin, spitting curses before the fight even started. The tension snapped the second the first blow landed. Baek Jumin was wild, and he immediately targeted Jaekyung’s weak spots. Each jab and kick seemed designed to break him. The pain in his foot intensifies. Baek Jumin caught onto it fast. He slammed his elbow into Jaekyung’s already injured shoulder, then swept his foot under Jaekyung’s right leg. Blood spilled from Jaekyung’s foot as he refused to fall. Dan watched from the sidelines, heart pounding. And the Jinx Chapter 50 ended, on the edge of collapse.
