The air in the apartment was too thick, heavy with the scent of citrus-scented disinfectant and the metallic tang of fear. Hongjoong sat on the edge of the sofa, his fingers digging into the worn fabric of his jeans. Every breath felt like trying to inhale through a straw filled with cotton. It wasn't a sharp pain—sharp would have been easier to categorize—it was a dull, dragging weight, as if his heart had turned into lead and was slowly sinking through his ribs.

Across the coffee table, Seonghwa was moving with a frantic, focused energy. He was packing a small nylon duffel bag, throwing in a clean hoodie, Hongjoong’s favorite thick socks, and a charging cable. Seonghwa’s movements were jerky, lacking his usual grace. His left side was turned toward Hongjoong, his "good ear" straining to catch the sound of the younger man’s labored breathing over the hum of the refrigerator.

"I can walk to the car, Hwa. You don't need to look at me like I’m made of glass," Hongjoong murmured, though his voice lacked its usual bite. It came out airy and thin.

Seonghwa didn't respond. He kept tucking a paperback book into the side pocket of the bag.

"Hwa," Hongjoong tried again, louder this time. He leaned forward, wincing as the movement sent a flutter through his chest that felt like a trapped bird beating its wings against a cage. "Seonghwa!"

Seonghwa jumped, spinning around. He blinked, his eyes wide and shimmering with unshed tears. He instinctively reached up to adjust his hearing aid, a habit he fell into whenever he felt he was losing his grip on a conversation. "Sorry. I—I didn't hear you. What?"

"I said I can walk," Hongjoong repeated, softening his expression. He reached out a trembling hand, and Seonghwa immediately abandoned the bag to take it. Seonghwa’s palm was cold, his thumb tracing the blue veins on the back of Hongjoong’s hand.

"We’re going back," Seonghwa whispered, his voice cracking. "The doctor said if the palpitations didn't settle by tonight, we had to come in. It’s been three hours, Joong. Your lips are pale."

"I know," Hongjoong said. He hated the admission. He hated that his body was a traitor, a faulty machine that kept breaking down just when they started to feel like they were living a normal life. They were supposed to go to the movies tonight. They were supposed to be arguing over which popcorn seasoning to get, not calculating how many minutes it would take to get to the emergency room.

Seonghwa helped him stand. The world tilted dangerously for a second, the edges of Hongjoong’s vision fraying into gray static. He leaned heavily into Seonghwa’s shoulder, burying his face in the soft wool of the older man’s sweater. He could hear the steady, rhythmic thrum of Seonghwa’s heart—strong, reliable, and effortless. He was jealous of that sound.

"I’ve got you," Seonghwa muttered, shifting his body to take more of Hongjoong’s weight. "Just keep your eyes on me."

The drive to the hospital was a blur of streetlights and the rhythmic clicking of the turn signal. Seonghwa drove with white-knuckled intensity, his head tilted slightly to the right so he could hear if Hongjoong’s breathing hitched or stopped. He didn't turn on the radio. Silence was safer; silence meant he wouldn't miss a single sound from the passenger seat.

When they reached the fluorescent glare of the hospital entrance, the reality of the situation finally settled into Hongjoong’s bones. The smell of the lobby—that sterile, cold scent of illness and recovery—made his stomach turn. He had spent too much of his twenty-five years in places like this.

The intake process was a flurry of questions he was too tired to answer. Seonghwa did most of the talking, his voice firm and steady despite the way his hands shook as he handed over Hongjoong’s medical ID.

"His name is Kim Hongjoong. Chronic heart failure, dilated cardiomyopathy," Seonghwa stated, his tone practiced. "He’s been experiencing increased shortness of breath and an irregular heart rate for the last six hours. His pulse is thready. He’s dizzy."

The nurse behind the desk looked up, her expression shifting from professional boredom to urgent concern as she looked at Hongjoong, who was slumped in a plastic chair, his head lolling back.

"Let's get him back," she said, signaling for an orderly with a wheelchair.

"I don't need the chair," Hongjoong protested weakly, but Seonghwa’s hand was already on his shoulder, pressing him down.

"Sit, Joong. Please," Seonghwa pleaded.

The emergency room was a labyrinth of beige curtains and the constant, rhythmic beeping of monitors—a symphony of mechanical hearts. They tucked Hongjoong into a bed in Cubicle 4. Within minutes, he was hooked up to a tangle of wires. The EKG monitor began its work, translating the chaotic electrical signals of his heart into a jagged green line on a black screen.

*Beep... beep-beep... beep...*

The rhythm was off. It skipped, then raced, then lagged. Hongjoong stared at the screen, mesmerized by his own dysfunction.

Seonghwa sat on a low stool by the bed, leaning in close. Because of the noise in the ER—the shouting of doctors, the rolling of gurneys, the hiss of oxygen—his hearing was struggling. He had turned the volume on his hearing aid up, but it only served to turn the background noise into a harsh, metallic roar. He focused entirely on Hongjoong’s face, reading his lips, watching the way his chest rose and fell.

The doctor, a tall man named Dr. Aris, stepped into the cubicle. He began talking quickly, gesturing toward the monitor.

"Mr. Kim, it looks like your ejection fraction has dropped again. We're seeing some significant arrhythmia. We’re going to start you on an IV drip of amiodarone to try and stabilize the rhythm, but we might need to discuss a more permanent intervention if this persists."

Hongjoong nodded, though he felt like he was underwater. "Is it... is it the valve?"

The doctor continued talking, but Seonghwa suddenly stood up, moving to the doctor’s right side. "Excuse me, Doctor," Seonghwa said, his voice loud in the small space. "Could you look at me when you speak? And a bit slower, please. I’m hard of hearing."

Dr. Aris paused, his expression softening. He turned fully toward Seonghwa, ensuring his mouth was visible. "Of course. I was saying that we are going to admit him. We need to monitor the medication's effect. If the heart doesn't respond to the IV, we may have to look at surgical options or adjusting his placement on the transplant list."

The word 'transplant' hung in the air like a guillotine.

Hongjoong closed his eyes. He felt Seonghwa’s hand find his under the thin hospital blanket. Seonghwa’s grip was so tight it almost hurt, but Hongjoong welcomed it. It was an anchor.

Once the doctor left and the nurse had finished starting the IV, a heavy silence fell between them, punctuated only by the erratic song of the monitor.

"You should go home," Hongjoong whispered. "It’s two in the morning. You have work tomorrow."

Seonghwa let out a dry, humorless laugh. He shifted his stool even closer, leaning his forehead against the metal railing of the bed. "I’m not going anywhere. I can’t hear you if I’m at home, can I?"

"Hwa, you're exhausted. Your ear is going to start aching if you keep that thing in all night."

Seonghwa reached up and flicked the hearing aid off. The world around him plunged into a muffled, watery silence, the sharp edges of the hospital noise smoothing out into a dull hum. He looked at Hongjoong, his eyes searching. "I turned it off. I don't need to hear the machines. I just need to see you."

Hongjoong felt a lump form in his throat. He reached out, tracing the line of Seonghwa’s jaw. "I'm scared this time," he admitted, the words barely a breath.

Seonghwa didn't hear the words, but he saw the way Hongjoong’s lips trembled, saw the flicker of terror in his dark eyes. He stood up and leaned over the railing, kissing Hongjoong’s forehead, his nose, and finally his lips. The kiss was slow, desperate, and tasted of salt.

"I'm right here," Seonghwa mouthed, making sure his movements were clear. "I’m not leaving."

They spent the night in that cramped cubicle. Hongjoong drifted in and out of a fitful sleep, chased by dreams of ticking clocks that suddenly stopped. Every time he jolted awake, gasping for air, Seonghwa was there. Seonghwa didn't sleep at all. He sat in the silence he had created for himself, his hand never leaving Hongjoong’s arm. He watched the green line on the monitor. He didn't need to hear the beeps to know when Hongjoong’s heart was struggling; he could see it in the way the line spiked and dipped.

At dawn, the other members of their small, makeshift family began to arrive. Yunho and Mingi were the first, looking disheveled and frantic. They burst into the waiting area, and eventually, a nurse led them back.

Mingi looked like he was about to burst into tears the moment he saw Hongjoong hooked up to the machines. He hovered at the foot of the bed, his large frame making the cubicle feel even smaller. "Hyung," he choked out.

Yunho was more composed, but the way he gripped the back of a chair told a different story. He looked at Seonghwa, noticing the lack of the hearing aid and the way Seonghwa’s eyes were bloodshot.

"How is he?" Yunho asked, keeping his voice low, though he knew Seonghwa wouldn't hear him. He tapped Seonghwa on the shoulder to get his attention.

Seonghwa looked up, blinking slowly. He reached for his hearing aid, clicking it back on. The sudden rush of sound—the hospital's morning shift change, the distant clatter of breakfast trays—made him wince.

"Stable, for now," Seonghwa said, his voice raspy. "The meds are working, but the doctor is worried. They’re talking about the list again."

Mingi let out a shaky breath, sitting down on the floor because there were no more chairs. "He’s too young for this. It’s not fair."

Hongjoong stirred, his eyes fluttering open. He saw the three of them gathered around him and managed a weak, lopsided smile. "Look at you all... acting like I’m already gone."

"Shut up, Joong," Yunho said, though there was no heat in it. He stepped forward and squeezed Hongjoong’s foot through the blanket. "We brought you some actual coffee from the place down the street. The hospital stuff is basically battery acid."

"I can't have caffeine, you idiot," Hongjoong teased, his voice sounding a little stronger.

"It’s for us," Mingi said, wiping his eyes with his sleeve. "We’re the ones who have to stay awake and make sure you don't try to sneak out to the recording studio."

Hongjoong laughed, but it turned into a cough that made the monitor's alarm chirp in warning. Seonghwa was instantly on his feet, his hand hovering over Hongjoong’s chest as if he could manually steady the heart beneath.

"Slow down," Seonghwa cautioned.

As the morning progressed, the rest of the group trickled in. San and Wooyoung arrived with a bag of pastries they knew Seonghwa wouldn't eat but hoped might tempt Hongjoong. Yeosang brought a stack of magazines and a sketchbook, knowing Hongjoong would get bored within the hour. Jongho was the last to arrive, looking uncharacteristically somber, carrying a small stuffed bear that he tried to hide behind his back before Wooyoung pointed it out.

The small cubicle was overflowing with people, with noise, and with a fierce, protective love. For a few hours, the hospital didn't feel like a place of transition or tragedy. It felt like a bunker.

"We’re going to take turns," Yunho announced, taking charge as he often did. "Two of us here at a time. Seonghwa, you’re going home with me to sleep for four hours. No arguments."

Seonghwa looked like he wanted to argue, his hand tightening on Hongjoong’s.

"Go, Hwa," Hongjoong said, looking up at him. "I’m not going anywhere. Look at all these guards I have. Jongho could probably take down the entire cardiology department if they looked at me wrong."

Jongho nodded solemnly. "I would."

Seonghwa sighed, his shoulders finally dropping. He leaned down, turning off his hearing aid one last time to block out the noise of the others, creating a private pocket of silence for just the two of them. He pressed his forehead against Hongjoong’s.

"I'll be back at noon," Seonghwa mouthed.

"I know," Hongjoong replied, his lips forming the words clearly.

As Seonghwa walked away, flanked by Yunho, he didn't look back. He didn't need to. He could still feel the phantom rhythm of Hongjoong’s heart against his palm—irregular, flickering, but still beating. And as long as it was beating, Seonghwa would keep listening, in whatever way he could.

Hongjoong watched them go, then turned his gaze back to the monitor. The jagged green line was still there, a constant reminder of the battle happening inside his chest. But as Wooyoung started telling a ridiculous story about a cat he’d seen in the parking lot, and San began to fuss over the pillows, the weight in Hongjoong’s chest felt just a little bit lighter.

His heart was broken, yes. It was tired and it was failing. But as he looked at the faces of the people surrounding him, he knew that it was still full. And for now, that had to be enough to keep the static at bay.
