Ffff

Hongjoong had always been the master of illusion. In the oversized sweaters and draped cardigans that defined his studio style, he looked like a delicate reed, a slender captain who moved with a lithe, almost fragile grace. It was the classic "sleeper build"—a frame that hid its secrets beneath layers of wool and expensive denim. But lately, the secrets were becoming impossible to keep.

The shift had started as a stress-relief tactic. Between the grueling world tour schedules and the endless nights of composing, Hongjoong had taken to the gym. He hadn't gone for the lean, shredded look of San or the sheer power of Mingi; he had focused, perhaps subconsciously, on his core and upper body. The result was a physiological anomaly that the rest of Ateez was currently struggling to process. While his waist remained tiny and his limbs stayed elegant, his chest had expanded into something formidable.

It was a Tuesday afternoon in the practice room, and the air conditioning was struggling to keep up with the humidity of eight hardworking idols. Hongjoong, wiped out from a three-hour dance block, had made the tactical error of wearing a deep-V neck compression shirt.

"Hyung," Wooyoung started, his voice uncharacteristically small. He was staring. He wasn't even trying to hide it. "Are you... wearing a chest plate? Is there armor under there?"

Hongjoong wiped sweat from his forehead with the back of his hand, his chest heaving with heavy breaths. Every time he inhaled, the fabric of the black shirt strained dangerously, the seam across the sternum looking like it was holding on for dear life. "Don't be ridiculous, Wooyoung. It’s just the pump from this morning."

"That’s not a pump, that’s a mountain range," San muttered, abandoning his water bottle to walk a slow, predatory circle around his leader. He reached out, his fingers hovering just inches from Hongjoong’s collarbone. "I spend half my life in the gym, and even I’m intimidated. How is your waist still that small while your pecs are doing... that?"

Hongjoong looked down at himself, finally noticing how the deep neckline of the shirt had migrated. Because of the sheer volume of his chest, the fabric was pushed outward, creating a shadow—a distinct, undeniable line of cleavage that shouldn't have been possible on someone of his stature.

"It’s just muscle," Hongjoong insisted, though his voice lacked conviction. He tried to pull the shirt up, but the material was so tight it just snapped back into place, emphasizing the swell of his pectorals even more.

Mingi, who had been uncharacteristically quiet, suddenly leaned in, his eyes wide behind his glasses. "It’s soft, right? I mean, it’s muscle, but it looks... plush."

Before Hongjoong could protest, Mingi’s large hand came out, his index finger poking the center of Hongjoong’s chest. The finger didn't hit bone; it sank into a firm, yet surprisingly full cushion of muscle.

"Mingi!" Hongjoong barked, though he didn't move away. He was too tired to fight the curiosity of his members.

"It’s bouncy," Mingi reported back to the group, his face full of wonder. "Like a high-end mattress. Hyung, I want to nap on you."

"Get in line," Seonghwa chimed in, walking over with a towel. He reached out, ostensibly to wipe the sweat from Hongjoong’s neck, but his gaze lingered on the way the Captain’s chest rose and fell. "I’ve been telling him his shirts are getting too small. I thought he was just buying the wrong size, but it’s the body that changed."

Seonghwa’s hand strayed, his thumb brushing against the top of the curve exposed by the V-neck. He let out a low whistle. "Hongjoong-ah, the fans are going to lose their minds. You can’t go on stage like this. It’s a safety hazard."

"It’s not a hazard," Hongjoong huffed, trying to maintain his dignity while four of his members were now effectively crowding his personal space to study his torso. "It’s just progress. I wanted more stamina for the choreography."

"Stamina?" Yunho laughed, joining the fray. He was the tallest, looking down at the view with a grin that was half-impressed and half-mischievous. "Hyung, you’ve developed your own gravitational pull. Look at Jongho. He’s been staring from the corner for ten minutes."

The youngest member, usually the most stoic, cleared his throat and looked away quickly when he was caught. "I was just wondering if the fabric tension was calculated or if we need to call the stylist for a replacement shirt before it rips."

"It’s not going to rip," Hongjoong said, just as he reached up to stretch his arms behind his head.

The sound of the fabric groaning was audible in the silent room. The V-neck widened, the edges of the shirt pulling taut against the rounded sides of his chest, making the central shadow even deeper.

"Oh my god," Wooyoung whispered, covering his mouth. "Hyung, please. Do that again. For science."

"I am not a science experiment," Hongjoong snapped, though a faint blush was creeping up his neck. He dropped his arms, but the damage was done. The members were now fully obsessed.

"I think we need to measure," San suggested, his eyes glinting. "For the stage outfits. We wouldn't want a wardrobe malfunction during 'Guerrilla,' would we? The high notes are dangerous enough without a button flying off and blinding someone."

"I have a tape measure in my bag," Yeosang volunteered, appearing out of nowhere with a calm, focused expression. He was always the quietest, but his dedication to the cause was unparalleled.

Before Hongjoong could protest, he was surrounded. Yeosang unrolled the yellow tape, and the others helped guide it around Hongjoong’s back.

"Keep your arms down, Hyung," Yunho instructed, gently holding Hongjoong’s shoulders to keep him still.

"This is harassment," Hongjoong grumbled, but he stayed still. He knew that when Ateez decided on a group activity, there was no stopping them.

Yeosang pulled the tape tight across the fullest part of Hongjoong’s chest. His eyes widened as he read the numbers. "He’s gained three inches since the last fitting. Three. And his waist hasn't changed at all."

"That’s an impossible ratio," Wooyoung cried, leaning in to see the tape for himself. His face was inches from Hongjoong’s sternum. "Hyung, what are you eating? Is it just protein powder and ambition?"

"It’s the weight of carrying this team," Hongjoong joked, though he winced when San poked his side.

"No, look at the definition here," San said, tracing the line where the muscle met the ribs. "It’s so dense. But the center... it’s so full. Hyung, if you wore a sheer shirt, the internet would actually collapse. We’d have to cancel the tour because the world would be in mourning."

"In mourning for what?" Hongjoong asked, confused.

"In mourning for their sanity," Seonghwa replied smoothly. He stepped closer, his hand coming up to rest flat against Hongjoong’s chest. He felt the steady, powerful thrum of the leader’s heart beneath the thick muscle. "You really have been working hard, haven't you?"

Hongjoong softened slightly at the genuine tone in Seonghwa’s voice. "I just wanted to feel stronger. I didn't realize it would... concentrate like this."

"It’s a good look," Seonghwa whispered, his eyes dropping back down to the cleavage created by the tight shirt. "A very good look. But maybe don't wear this specific shirt to the company meeting later."

"Why not?"

"Because the CEO won't be able to look you in the eye," Mingi piped up, still fascinated by the way the muscle moved when Hongjoong breathed. "I can barely look you in the eye, and I’ve seen you in the shower."

Hongjoong groaned, burying his face in his hands. "I hate all of you. Truly."

"You love us," Wooyoung chirped, daring to reach out and give one of Hongjoong’s pecs a playful squeeze. "And you love that we appreciate your hard work. Honestly, Hyung, you should be proud. You’ve achieved the ultimate Captain look. You look like a superhero."

"A superhero who needs a larger size in hoodies," Yeosang added, finally retracting the tape measure.

The rest of the afternoon was a lost cause. Every time Hongjoong moved, every time he leaned over to check the monitor or reached for his water, seven pairs of eyes followed the movement of his chest. It became a game of chicken; Hongjoong tried to act natural while the others tried to see just how much the fabric could handle.

During a break, Hongjoong sat on the floor, leaning back on his elbows. This was a mistake. The position pushed his chest forward and up, the compression shirt struggling to contain the sheer mass.

"Hyung, stop," Jongho said suddenly, looking up from his phone.

"Stop what?"

"Existing like that," the maknae said, his ears turning red. "It’s distracting. I’m trying to practice my scales and I just keep thinking about how you’re going to fit into your suit for the awards show next week."

"I'll fit," Hongjoong insisted.

"You won't," Yunho said, sitting down next to him and casually slinging an arm over Hongjoong’s shoulders. The movement pulled Hongjoong closer, and Yunho couldn't resist—he let his hand drop, his fingers grazing the firm swell of Hongjoong’s chest. "You’re going to pop a button. It’s inevitable."

Hongjoong looked at his members—his family—and saw the mixture of awe, mischief, and genuine admiration in their eyes. He looked down at himself, finally accepting that his 'sleeper build' was officially retired. He was no longer just the slim, ethereal leader. He was the Captain with a chest that commanded its own Zip Code.

"Fine," Hongjoong sighed, a small, proud smirk finally tugging at his lips. "If it’s that distracting, I’ll buy some new shirts. But don't think this means I'm stopping the chest days."

"Please don't stop," San said earnestly, clasping his hands together. "For the sake of the team. For the sake of the vision."

"The vision?"

"The vision of you in a harness next comeback," Wooyoung whispered, looking like he’d just had a religious experience.

Hongjoong threw his sweat-soaked towel at Wooyoung’s face, but he couldn't stop the laugh that bubbled up. He felt strong, he felt healthy, and if his members wanted to obsess over his new physique, who was he to stop them?

As they packed up to leave, Seonghwa lingered by the door, waiting for Hongjoong. As the leader walked past, Seonghwa reached out, his hand lingering one last time on the center of Hongjoong’s chest, his fingers dipping slightly into the valley there.

"You really did a good job, Joong-ah," Seonghwa murmured, his voice low and full of a different kind of appreciation.

Hongjoong felt a shiver that had nothing to do with the air conditioning. "Thanks, Hwa."

"But seriously," Seonghwa added, his eyes dancing with mischief as they headed toward the van. "Burn that shirt. Or give it to me. I want to see if it actually has magical stretching properties."

"In your dreams," Hongjoong laughed, heading out into the sunlight, perfectly aware that every step he took made the fabric dance over his skin, and perfectly aware that seven pairs of eyes were watching his back—and his front—with rapt attention.

The Captain had a new armor, and it seemed the crew was more than happy to help him polish it.
