A crack AU. Two male best friends in college, Hyukjae and nerdy Donghae. Hyukjae was involved in an experiment (by professor Kim Heechul) where he turns into a voluptuous lady after taking the professor concoction. He could turn to male only after someone comes in him. So he could only ask his best friend Donghae to turn him back into a male. Donghae who had always love Hyukjae (even as a male) agreed willingly.

Chapter 6: Morning After Paradox

The grey light before dawn was a thief. It stole the sharp edges from the room, turning the piles of clothes into soft hills and the scattered textbooks into vague monuments. It also stole, for a few precious minutes, the strangeness.

Donghae woke to warmth. A solid, breathing warmth nestled against his side, a head heavy on his shoulder, and the faint tickle of long hair against his cheek. His arm was numb, pinned beneath a weight. He blinked, his mind fogged with the residue of a sleep he hadn’t expected to find.

The events of the night rushed back not as a jolt, but as a slow, cold seep—the confession in the dark, the impossible shift, the tense, terrible distance finally bridged only to be ripped open again by a shimmer of reality. He’d fallen asleep staring at the ceiling, Hyukjae a careful, still shape on the far side of the bed, the space between them a canyon.

Sometime in the night, the canyon had closed.

He turned his head slowly, muscles protesting. Hyukjae was asleep. Her—his—face was relaxed, softened by slumber. The striking feminine features were familiar to him now in a way that felt traitorous. The long lashes fanned against cheekbones that were high and elegant, the lips parted just slightly. In sleep, the performance was gone. This was just Hyukjae, seeking warmth, seeking comfort, seeking him, as he always had after a rough night, a failed exam, a broken heart. The body was different, but the instinct was ancient.

Donghae’s breath caught. He didn’t move. He wanted to trap this moment in amber, this fragile, peaceful truce where the world made a terrible, beautiful kind of sense. The scent of vanilla and clean sweat filled his lungs. His numb arm began to prickle with returning circulation, a thousand tiny pins and needles.

Hyukjae stirred. A soft sigh escaped her lips, her brow furrowing slightly. She nuzzled unconsciously into the hollow of his collarbone, her nose cold against his skin. Then her eyes fluttered open.

For a heartbeat, there was only the hazy confusion of waking. Her eyes, dark and soft with sleep, met his. They blinked, slow and uncomprehending. Donghae watched the moment of recognition dawn—not of who he was, but of what she was, of where they were, of the impossible tangle of limbs and sheets and history.

A slow, sleepy smile spread across her face. It was lazy, unguarded, and utterly devastating.

“Morning, lover,” she murmured, her voice raspy with sleep, that same sweet, layered tone that now felt like a physical touch.

The words, so casual, so laden with a history that was only hours old, shattered the amber. The cold seep became a flood.

Donghae stiffened. The warmth against him suddenly felt like a branding iron. He pulled his arm free, the sudden movement abrupt. Hyukjae’s head slipped from his shoulder, thumping softly onto the pillow. The sleepy smile vanished, replaced by startled clarity.

“Shit,” Hyukjae said, pushing herself up on her elbows. The sheet fell, and she yanked it back up, a flash of self-consciousness that was new.“Sorry. Force of habit. Waking up next to someone.” She ran a hand through her long hair, wincing as her fingers caught in a tangle. “God, this is annoying. How do you deal with all this hair?”

She was deflecting, building a wall of casual complaint brick by brick. Donghae sat up, putting more distance between them. The grey light felt accusing now. “We need a plan.”

“Breakfast?” Hyukjae suggested, peering at him with a cautious look. “I’m starving. Your metabolism does backflips when your cellular structure is rewriting itself on the fly, apparently.”

“Hyukjae.”

“What? It’s true. I could eat a whole samgyeopsal by myself.” She sighed, seeing his expression. “Fine. The plan. Step one: you lend me some clothes that won’t make me look like I’m drowning. Step two: we order enough food to feed a small army. Step three: we figure out how to kill forty-eight hours without…” She gestured vaguely between them, at the bed. “…without a repeat of last night’s unscheduled programming.”

“And step four?” Donghae asked, his voice flat.

“Step four is Monday. Heechul. Answers.” Hyukjae swung her legs out of bed, keeping the sheet wrapped around her like a toga. She stood, facing the window. The dawn light outlined her form through the thin cotton. “Look, about last night… what I said about convincing me.That was stupid. I was freaked out and trying to make a joke out of it. Bad habit.” She glanced back over her shoulder, her profile sharp against the light. “You were right. We’re not an experiment. Not anymore.”

The admission hung in the quiet room. Donghae finally climbed out of bed, his own body feeling stiff and unfamiliar. He went to his dresser, moving by rote. He pulled out a pair of soft grey sweatpants and a black hoodie, the cuffs frayed. He held them out, not looking at her directly. “These’ll be big, but they’ll do.”

Hyukjae took the clothes, their fingers brushing. “Thanks.”

While she disappeared into the small bathroom, Donghae stood in the center of his room, adrift. The bed was a battlefield. He mechanically straightened the sheets, trying to erase the evidence of the night, but the scent lingered. He heard the water run, the rustle of fabric.

When she emerged, she was almost swallowed by his clothes. The sweatpants were rolled at the ankles, the hoodie hung past her hips, the sleeves covering her hands. She’d gathered her hair into a messy bun on top of her head, a few strands escaping. With the dramatic framing of her hair gone, her face looked younger, more vulnerable. More like him.

“See?” she said, holding her arms out. “Comfy. Androgynous chic.”

“You look like a kid who raided their big brother’s closet,” Donghae said, and the faintest hint of a smile touched his mouth.

“Exactly the look I was going for.” She padded to the kitchenette, opening cupboards with the familiarity of someone who’d done it a thousand times. “We have ramyeon, cereal that’s probably stale, and… is this kimchi from last month?”

“Probably.”

“Great. We’re ordering in.” She grabbed Donghae’s phone from the charger, knowing his passcode. She flopped onto the small couch, tucking her feet beneath her. “What do you want? Something greasy. Something that says ‘I survived a night of profound ontological crisis.’ Fried chicken?”

Donghae joined her, sitting on the opposite end, leaving a cushion between them. “Sure. Chicken.”

She ordered, her voice bright and normal over the phone, a performance for the delivery person. When she hung up, the silence returned, but it was different now. Clothed, in the daylight, the tension had morphed from electric to dense, a heavy blanket.

“So,” Hyukjae said, picking at a loose thread on the couch. “While we wait for cardiac arrest in a bucket… what do we do?”

“We could… not talk about it,” Donghae offered.

“Tempting. But it’s all I can think about. It’s like having a constant, full-body phantom limb. But the limb is… you know. Different.” She looked at him. “What are you thinking about?”

Donghae stared at his hands. He was thinking about the warmth of a body against his in the grey dawn. He was thinking about the word “lover” spoken in a sleep-raspy voice. He was thinking about the terrifying truth that had curled in his chest since he’d pulled his arm away: that for one peaceful moment, he hadn’t wanted to.

“I’m thinking,” he said slowly, “that when you changed back the first time, it was after we… connected. Physically. And last night, we connected again. Really connected. And then you changed. But not back.”

Hyukjae’s fingers stilled on the thread. “You think it’s emotional? Not just physical?”

“I think Heechul’s experiment is a mess. I think we’re feeling around in the dark.” He finally met her gaze. “I think when I said we shouldn’t use each other, I was protecting myself. Not just you.”

Hyukjae’s eyes widened slightly. “From what?”

“From wanting it,” Donghae whispered. The admission was pulled from a deeper, darker place than last night’s confession. “From wanting you, like that, even now. Even like this. Because if it’s just a switch, then last night meant nothing. And if it’s not…” He trailed off, the implication too vast to voice.

The knock at the door was violently loud. They both jumped.

“Chicken salvation,” Hyukjae said, scrambling up. She moved to the door, then stopped, looking back at him. Her expression was a complex map of confusion, fear, and a dawning, painful hope. “We’re not done with this conversation.”

“I know,” Donghae said.

She opened the door, accepting the large bag, exchanging cheerful thanks with the delivery man. She brought the feast to the low table, the smell of fried food cutting through the vanilla and tension.

They ate on the floor, ripping meat from bones, grease shining on their fingers. It was a ritual, a return to a hundred shared meals. For a while, they talked about nothing—a ridiculous drama Hyukjae was watching, a professor going on sabbatical, the dance team’s new routine.

But the unsaid words swirled around them, thickening the air with every silent moment.

As Hyukjae licked salt from her thumb, she looked at him, her gaze steady and serious. “You said you haven’t been able to run from me since we were sixteen,” she said, echoing his words from the dark. “What did you mean?”

Donghae put his chicken bone down, wiping his hands on a napkin. The barrier of food was gone. There was nowhere left to hide.

“I meant I’ve been in love with you,” he said, the words clear and quiet in the sunlit room, “since the day you dragged me into that stupid dance practice room and refused to let me leave until I could at least not trip over my own feet. Since before I knew what to call it.”

Hyukjae stopped breathing. She just stared, a piece of cabbage slipping from her lip back onto the plate.

“And last night,” Donghae continued, the momentum carrying him forward into the terrifying open, “wasn’t about an experiment. It was about that. It was always about that. And this…” He gestured to her, to the feminine form swimming in his hoodie. “This is just… the most complicated version of you I’ve ever had to love.”

A single tear escaped, tracing a quick path down Hyukjae’s cheek. She didn’t wipe it away. “Donghae…”

“I don’t know what to do,” he confessed, his own vision blurring. “Do I love the you that’s in here?” He tapped his own temple. “Or the you I held last night?Are they separate? Can they be? I want you. But which you is mine to want?”

Hyukjae moved then. She crossed the space between them on her knees, the greasy containers forgotten. She didn’t kiss him. She didn’t embrace him. She simply took his hands, her slender fingers gripping his tightly, grease and all.

“They’re both me,” she said, her voice fierce and trembling. “They’re just… housed differently. And it’s a fucking nightmare. And it’s confusing. And I’m scared. But you…” She squeezed his hands. “You’re the only thing in this that isn’t confusing. You’re the only constant. Before, during, after. Male, female, whatever. It’s always been you.”

She brought his greasy fingers to her lips and pressed a kiss to his knuckles, a gesture so profoundly tender it broke something open inside Donghae’s chest.

“So want me,” she whispered against his skin. “Just want me. And we’ll figure out the rest as we go. Even if we have to burn Heechul’s lab down on Monday.”

Outside, the day had properly begun. Sunlight streamed through the window, landing on their clasped hands, on the wreckage of their breakfast, on the messy, impossible truth they had finally laid bare. The next forty-eight hours stretched ahead, no longer a prison sentence, but a fragile, charged breathing space—a threshold. They were on the other side of something now, and there was no map for the territory ahead, only the anchor of each other’s hands, held tight in the clear light of morning.
