The tension between Jaekyung and Kim Dan intensifies as their complicated arrangement continues. Dan struggles emotionally and physically, caught between financial desperation and Jaekyung’s dominating behavior. Despite Jaekyung’s harsh treatment, moments of vulnerability begin to surface. Dan, overwhelmed and conflicted, starts seeing glimpses of care beneath Jaekyung’s rough exterior, but the imbalance in their relationship remains unsettling. Let us move on further to find out what happens in Jinx Chapter 21-30!
Jinx Chapter 21: Quiet Shift

Jinx Chapter 21 opens with raw intensity as Dan, overwhelmed with fear for his grandmother, shoves Jaekyung away. Tears stream down his face as he demands to know whether Jaekyung values intimacy more than a person’s life. This vulnerable outburst stuns Jaekyung, who is left speechless before abruptly rushing to the hospital. There, the nurse explains that the incident was due to a previously undetected side effect of the chemotherapy and that Dan’s grandmother is now stable. She gently urges that Dan should be present more often, as the treatment is taxing and emotional support is essential.
The weight of this advice visibly shakes Dan, who collapses to the floor, emotionally drained. Gathering himself, Dan quietly enters his grandmother’s room and sits beside her unconscious form, clutching her hand. His guilt spills out in hushed apologies as he blames himself for not being by her side when it mattered. He spends the entire night at the hospital, refusing to leave her side.
An Unexpected Presence
The next morning is cold and gray, mirroring Dan’s state of mind. When he returns to the penthouse, barely able to keep his eyes open, he tells Jaekyung he’ll sleep only an hour so he won’t be late for work. Jaekyung, without a word, heads off for his morning jog, leaving Dan to rest. A short while later, Dan is jolted awake by his ringing phone and multiple missed calls from the hospital and the nursing staff. Panic instantly grips him, and he races back, heart pounding with dread. But when he bursts into his grandmother’s room, he’s met with a completely unexpected sight: Jaekyung calmly sitting beside her. Confused and taken aback, Dan tries to process the situation. The nurse casually mentions that since Dan was sick and couldn’t answer the call, his “friend” Jaekyung picked up instead and came in his place. She praises Jaekyung’s kindness and good looks, even noting how much his grandmother seems to enjoy his company.
Dan is left baffled. Why would Jaekyung, a man who has always been distant, arrogant, and emotionally detached, go out of his way to be here? The gesture doesn’t quite fit the man he thought he knew. This quiet act of care plants the seed of doubt in Dan’s mind, leaving him to question whether there’s more to Jaekyung than he initially believed, ending Jinx Chapter 21.
Jinx Chapter 22: Kindness

Jinx Chapter 22 deepens the emotional understanding between Kim Dan and Jaekyung, revealing kindness and quiet shifts in their relationship. It opens with Dan asking to speak with Jaekyung. Though busy with his training schedule, Jaekyung agrees. As he prepares to leave the hospital room, Dan’s grandmother sweetly asks to hold Jaekyung’s hand one last time, thanking him sincerely. It is a simple gesture that reflects the deep impression he has left on her. Outside in the corridor, Dan questions Jaekyung about his visit, saying it was not necessary. Jaekyung brushes it off coldly, claiming he only showed up because Dan was too sick to answer the call and, sarcastically, because he wanted to check if Dan’s grandma even existed, since Dan always talks about her.
Dan, feeling guilty, apologizes for yelling at Jaekyung the night before. In return, Jaekyung delivers a warning. This will be the first and last time he tolerates that kind of outburst. Dan accepts with a bow and thanks him again, noting how happy his grandmother seemed, something he has not seen in a long time. Jaekyung, as always, offers no response. He just walks away, silent and unreadable, but his actions continue to speak louder than his words.
Unspoken Bonds
Back inside, Dan chats with his grandmother and the nurse, both of whom gush about how kind, sweet, and handsome Jaekyung is. Dan is stunned. Kind and sweet are not exactly the words he would have used. The nurse then casually informs him that Jaekyung had quietly paid off a few months’ worth of his grandmother’s medical expenses. The news completely shakes Dan. Despite everything, Jaekyung had helped again. Dan is left wondering what exactly Jaekyung’s intentions are.
The next morning, Jaekyung catches Dan in the kitchen cooking. Initially annoyed, he warns Dan not to mess up his nutrition plan, but after seeing and tasting the food, he softens. Dan humbly says it is the least he can do and promises to continue cooking as a small way to repay him. Jaekyung enjoys the meal and casually approves of Dan cooking for him every morning. At training, Jaekyung’s teammates complain about their bland meals, prompting someone to ask what Jaekyung eats. He casually replies, “Whatever Doc Dan makes.” The room falls into stunned silence as Jaekyung then adds that Dan now lives with him. Dan nearly chokes, shocked at how casually Jaekyung revealed such a private detail. In a space where Jaekyung rarely lets anyone in, Dan might just be the first. With that surprising shift, Jinx Chapter 22 ends.
Jinx Chapter 23: Almost Caught!

Jinx Chapter 23 begins with Jaekyung in the ring, securing yet another victory in his MMA match. The crowd is electric, and among the spectators is trainee Hwang Yoon Gu, who watches with wide-eyed admiration. Jaekyung is everything he aspires to be: strong, respected, and dominant in the ring. He idolizes him not only as a fighter but as a mentor. However, the excitement of the match fades quickly for Yoon Gu. Most of the gym’s members leave for the fight, but he is left behind, stuck with tasks and training alone. He feels overlooked and unimportant, and this frustration only intensifies around Kim Dan. Yoon Gu quietly resents Dan.
To him, Dan is an outsider who has somehow earned Jaekyung’s attention and presence, despite having no real place in the gym or in the sport. When Jaekyung returns to the gym, Yoon Gu watches as he speaks casually with Dan. Their comfort with each other and the fact that they live together unsettles him. It should not mean anything, he tells himself.
Blurred Lines And Suspicion
As training begins, Yoon Gu eagerly asks Jaekyung to hold the mittens for him, clearly hoping for one-on-one time. Jaekyung declines, stating that Yoon Gu’s back posture still needs work. Yoon Gu has been working hard on that specific issue since he joined. Disheartened, he sits on a bench, drinking water and trying to compose himself. Dan, noticing his mood, quietly checks on him and asks if he is alright. Yoon Gu brushes it off, but then casually asks why Dan did not go to the match. Dan replies that he wanted to, but Jaekyung would not have allowed it. That response shocks Yoon Gu.
Does Dan need Jaekyung’s permission to attend a match? Just how close are they? Before he can dwell on it, Jaekyung walks over and grabs Dan by the wrist, pulling him away toward the treatment room. Yoon Gu assumes it is for some routine physical therapy. He resumes his training, but shortly after, a loud crash and the sound of protest echo from the treatment room. Yoon Gu freezes, confused and slightly alarmed. Something is happening, and it does not sound like part of a normal session. He is left wondering what kind of relationship really exists between Jaekyung and Dan as the Jinx Chapter 23 ends.
Jinx Chapter 24: An Iced Americano

Jinx Chapter 24 picks up right where the previous chapter left off, with tension behind the closed doors of the training room. Jaekyung, driven by his unchecked desire, tries to initiate something physical with Dan. Dan, clearly uncomfortable, resists. The risk of being caught is too high, especially with Hwang Yoon Gu nearby. Dan expresses his concern, worried that if Yoon Gu finds out, the consequences could be damaging. His anxiety is real and visible, but Jaekyung brushes off the concern with characteristic indifference.
Assuming that Dan’s hesitation is not about consent but rather about Yoon Gu’s presence, Jaekyung comes up with a solution. He strides out of the room and casually hands Yoon Gu his sleek black AMEX card, telling him to go get him a coffee. To Yoon Gu, this is a huge moment. It’s his first personal errand for Jaekyung, and it feels like a step closer to being noticed by the man he idolizes. Excited and honored, he runs off without a second thought.
Jaekyung’s Relentless Dominance
Back in the training room, Jaekyung returns to Dan with full control over the situation. With Yoon Gu temporarily out of the picture, he resumes what he started. The atmosphere is heavy, the room too quiet except for the sounds that follow. Dan, cornered in every sense, is left enduring Jaekyung’s dominance as his objections are slowly overwhelmed. As Jaekyung’s actions intensify, Dan’s discomfort only grows, but he has little room to push back. Just when the moment reaches its peak, Jaekyung’s phone suddenly buzzes. It’s Yoon Gu, calling in the middle of everything. The sound cuts through the tension. The interruption is sharp and unwelcome, but it serves as a reminder of how fragile their situation really is.
Jinx Chapter 24 ends in this uncomfortable pause, with Yoon Gu waiting on the other end of the line, oblivious to what he’s just interrupted. Dan is left shaken, both emotionally and physically, while Jaekyung’s expression remains unreadable. The line between control and care continues to blur, leaving more questions than answers. As the door remains closed and the phone keeps ringing, one thing becomes clear: whatever is happening between them, it is becoming impossible to hide.
Jinx Chapter 25: The Sparring

Jinx Chapter 25 begins with Yoon Gu returning to the gym, holding the coffee Jaekyung sent him to get. As he enters, he finds Kim Dan quietly cleaning the couch, looking exhausted. He casually asks about Jaekyung, and Dan replies that he went to take a shower. As Dan tries to stand up, he winces in pain, clearly sore from what had occurred earlier. Yoon Gu notices and, with concern etched on his face, asks if something happened. His mind jumps to conclusions he probably should not entertain, but he tries to brush it off. That night, however, those thoughts followed him into his sleep. He finds himself dreaming of Dan kissing Jaekyung and dominating him, and the images disturb his peace. Yoon Gu ends up spending the entire night tossing and turning, unable to sleep. The jealousy and confusion begin to simmer beneath the surface.
Into The Ring
The next day, training resumes as usual. The athletes are sparring in pairs, working on techniques and endurance. Off to the side, Dan is also sparring, learning simple moves. As Jaekyung’s medical support, he wants to understand how athletes’ muscles react under pressure so he can provide better care, especially since Jaekyung is the top priority. With no one else to spar with, Yoon Gu offers to teach Dan some basic jujitsu techniques. They begin working together, and while chatting about Jaekyung during a practice hold, Yoon Gu accidentally applies too much pressure and chokes Dan.
Other members of the gym turn toward them, with concern on their faces. Yoon Gu is scolded for being careless. At that moment, Jaekyung enters and asks what happened, and Dan quickly explains that he had been trying to learn jujitsu to improve his understanding of athletic movement and performance. Jaekyung responds with a sly grin and unexpectedly offers to spar with Dan himself. This shocks everyone present. Jaekyung rarely sparred with anyone, and when he did, it ended with someone getting injured. Still, Dan prepares himself, wearing full safety gear as he steps into the ring. Jinx Chapter 25 closes with Jaekyung and Dan facing each other under the harsh gym lights, tension thick in the air, and everyone watching closely, unsure of what will happen next.
Jinx Chapter 26: One Hit, One Wish

The gym is filled with energy as the sparring between Jaekyung and Kim Dan begins in Jinx Chapter 26. Jaekyung sets the rules in front of everyone: if Dan manages to land three hits on him within the three-minute rounds, he wins and earns one wish. The challenge feels nearly impossible, but Dan nods, determined to try. The first round begins. Jaekyung, fast and relentless, lands blow after blow while Dan struggles to keep up. The difference in skill is obvious, and the match seems one-sided. The second round is no better. Dan is still standing but bruised and tired, yet his resolve doesn’t waver. The crowd murmurs among themselves. Why is Jaekyung going this hard on someone so inexperienced? What exactly is their relationship?
Victorious Kim Dan!
As the third and final round starts, Dan surprises everyone by holding his ground more confidently. He suddenly moves in and clings tightly to Jaekyung’s body, attempting a takedown. It’s an unusual move, but it stalls Jaekyung’s momentum. Just then, the coach walks into the gym, drawing everyone’s attention toward the door for just a split second. Dan uses this tiny opening and strikes Jaekyung cleanly. It’s the third hit. He did it. Silence falls for a moment before the room erupts into gasps and cheers. Kim Dan, the quiet doctor with barely any fight training, just beat Jaekyung at his own game.
As promised, Jaekyung asks Dan what wish he wants granted. Without hesitation, Dan asks him to spar with Yoon Gu. The request throws everyone off. Jaekyung calls it weird, but the wish is granted. Yoon Gu is stunned. It was something he had only dreamed of, and now it’s happening because of Dan. All the doubt and resentment Yoon Gu had for Dan melted away in an instant. He finally sees Dan for who he is, kind and selfless. The gym is still buzzing as the match ends. The manager storms in and smacks Jaekyung for recklessly sparring with Dan, shouting that he could have injured him. Jaekyung dodges the scolding and runs off, leaving behind laughter, admiration, and a very unexpected champion.

Jinx Chapter 27: Day Off

Jinx Chapter 27 begins with Dan and Jaekyung visiting the hospital for a full-body checkup following the recent sparring match. The results are in, and the doctor asks to speak with Dan privately. The report is serious. Jaekyung’s body, especially his shoulders and joints, is showing signs of strain. If he continues pushing himself without rest or proper care, it could lead to long-term damage. The news weighs heavily on Dan, who understands just how hard Jaekyung pushes his limits every day.
Concerned, Dan takes the results to Jaekyung’s coach. As expected, the coach already knows Jaekyung won’t listen to him. However, he sees a chance with Dan. Jaekyung might be more open to listening if Dan is the one to deliver the advice. Dan, although hesitant, manages to convince Jaekyung to take it easy for a few days, no training, no fighting, just rest. But now Dan is stuck with the bigger challenge: keeping Jaekyung entertained.
Time For Board Games!
After staying up all night searching for harmless ways to distract him, Dan lands on board games. That afternoon, the two sit down to play, and Jaekyung loses every single round. One game after another, Dan beats him with ease. Jaekyung, naturally competitive, grows more and more irritated. He accuses Dan of picking games just to humiliate him, finding joy in beating someone who usually dominates. His pride bruised, Jaekyung storms off to the swimming pool on the penthouse floor. Dan follows, reminding him gently to be careful with his shoulder. But then Dan casually admits he doesn’t know how to swim.
Jaekyung, already annoyed, sees an opportunity and yanks Dan into the pool by the ankle. Dan splashes in, panicking for a moment before realizing the pool is shallow, barely five feet. Flustered and embarrassed, he drags himself back to the edge. He wraps a towel around himself and tries to wipe off the water, cheeks flushed. Jaekyung stands nearby, watching him in silence. His eyes trail over Dan’s soaked skin, taking in the sight without shame. Something shifts in the air. He walks over slowly, his expression unreadable but intense. Towering over Dan, he leans in, saying he wants to try something a little more exciting than board games.
Jinx Chapter 28: In The Pool

In Jinx Chapter 28, the mood is heavy and charged. Jaekyung, worn out from always leading but still craving control, decides to let Dan take the top position, but as part of a more intense, dominating play. The atmosphere shifts as Jaekyung treats Dan not tenderly, but almost like a plaything, pushing boundaries and driving the encounter with rough, demanding energy.
When they move to the pool, the environment intensifies the experience instead of softening it. The water makes everything more challenging, movements are harder, breaths come shorter, and every touch is amplified. Jaekyung’s dominance is clear, making Dan submit and pushing him harder, both physically and emotionally. It tests Dan, leaving him feeling both exposed and overwhelmed. By the end, Dan is crying, not just from the strange feelings the water brings, but from the harshness and intensity of Jaekyung’s treatment. The moment is rough, filled with tension and ache, making the tears almost inevitable. The sadness is emotional and physical. Dan’s tears carry confusion, hurt, and longing for something gentler that he can’t picture anymore, ending Jinx Chapter 28.
Jinx Chapter 29: A Different Type Of Rest

In Jinx Chapter 29, Dan wakes up, still damp from the pool. The last thing he remembers is leaning against the edge. Now it’s dark outside, and the penthouse is quiet. The silence is comforting, but his heart feels heavier than before. Something inside him has started to shift. He’s no longer sure if it’s confusion, fear, or something dangerously close to affection. He walks into the living room and pauses. There’s Jaekyung, still awake, seated comfortably on the couch, wearing glasses and staring at the television. He didn’t know Jaekyung wore glasses, and he wasn’t prepared for how oddly attractive it was. For a moment, the world slows. He moves quietly and takes a seat beside him, the distance between them small but charged.
The film flickers quietly on the screen. Dan asks why he’s still up, and Jaekyung explains that he suffers from insomnia. Sleeping pills are off-limits because of anti-doping protocols before matches, so watching films is the only thing that helps him settle down. The soft glow of the screen reflects on both their faces as the silence stretches between them. Then Jaekyung speaks again, this time more directly. He asks why Dan used his sparring wish on Yoon Gu instead of asking for something for himself.
Movie Night With Jaekyung
Dan hesitates, but answers truthfully. He says that Yoon Gu worships Jaekyung, and he deserves that opportunity. But Jaekyung doesn’t let it go. He asks again, what would Dan have wished for if Yoon Gu hadn’t been there? Dan’s response is quiet but bold. He says he would’ve asked Jaekyung to use protection next time. The air stills for a moment, charged with meaning. Jaekyung stares at him, face unreadable, and then shifts, leaning in, moving closer as he refuses his request because it’s more fun without it until he’s towering over Dan again. Their usual rhythm returns, but something is different.
The pressure, the control… It’s still there, but this time, Dan doesn’t resist the same way. But as Jaekyung leans in again, Dan doesn’t pull away. He seems to fancy this control and domination. It might be something else entirely. The next morning, a showbiz van passes by… Choi Heesung. An actor who seems to know Jaekyung and has a meeting scheduled. Will Dan’s feelings be reciprocated by Jaekyung? With confusion still lingering on, Jinx Chapter 29 comes to an end.
Jinx Chapter 30: Is That Jealousy?!

In Jinx Chapter 30, the gym buzzes with its usual energy when a new yet familiar face walks through the doors. Choi Heesung, a well-known celebrity from the entertainment industry, arrives for his personalized training session. Tall, polished, and charismatic, Heesung is a popular figure, known for shooting commercials and variety shows. Dan checks in with the coach, curious if they’ve worked together before. The coach nods, explaining that Heesung and Jaekyung have crossed paths during shoots and that training him is not just about fitness, it’s also good PR. Heesung pays a hefty sum for each session, after all. As Jaekyung begins guiding Heesung through the workout, Heesung’s eyes drift toward Dan. There’s a flicker of recognition in his gaze. He pulls out his phone, casually recording vlog clips and snapping a few gym selfies for his followers. Jaekyung’s expression darkens at the sight, clearly annoyed by the distraction, but he says nothing.
A Rival?!
After the session, Heesung winces and grabs at his wrist, claiming he may have sprained it during one of the drills. Dan, ever the professional, steps forward and offers to take a look. Heesung nods and extends his hand, but the moment Dan touches him, something shifts in the air. Dan checks the wrist gently, his fingers moving with care and precision. He compliments Heesung’s acting skills in passing, trying to keep the interaction light. But Heesung doesn’t seem to hear him. His focus is entirely on Dan. His hand lingers a little too long. It’s uncomfortable. From across the room, Jaekyung watches them.
Eyes fixed on the scene unfolding in front of him. Something flashes in his eyes, an emotion that’s hard to define. Jealousy? Possessiveness? Perhaps something deeper that even he hasn’t figured out yet? Jinx Chapter 30 ends with a silent stare and a question hanging in the air: What exactly does Jaekyung feel?
