Part :- 01 》Will you sleep with him
The airport doors slid open, and cold Korean air brushed against her face. You adjusted your bag on your shoulder, eyes scanning the unfamiliar surroundings. It had been a long flight from Australia, but the weight in your chest had nothing to do with exhaustion.
The house came into view after a short drive—quiet, elegant, almost too perfect. You hesitated for a second before stepping inside.
“ Y/n ”
The moment Suha saw you, her voice cracked. You didn’t even get a chance to respond before she rushed forward and pulled you into a tight hug.
“I missed you,” Suha whispered.
Your grip tightened slightly. “I missed you too.”
A sudden sound broke the moment—firm footsteps coming down the stairs. Both of you pulled apart. You turned your head. Its Jungkook, he walked down slowly, his presence immediately shifting the atmosphere in the room. Calm. Cold. Controlled. His eyes barely glanced at you before landing on Suha.
“You’re late,” he said flatly.
Suha lowered her gaze immediately. “I was talking to my sister…”
“I don’t care,” he interrupted.
Your brows furrowed slightly. He didn’t even try to hide how distant he was. As he walked past, you followed him with your eyes, confused… irritated.
You leaned slightly toward Suha and whispered, “Why is he so rude?”
Suha didn’t answer right away and that silence… somehow felt heavier than the words he had spoken. Suha look at Jungkook instead
Suha finally spoke, softer this time “Koo… my sister.”
His voice came after a pause “Hm.”
Just that. No warmth. No question. No effort. You glanced toward the direction of the stairs again, but he had already moved away.
Suha gently took your hand. “Come, I’ll show you your room.”
You followed her upstairs, still trying to shake off the strange heaviness that clung to the house. The room she showed you was neat, minimal, and too quiet.
Suha said quickly, as if reading your thoughts. “I wanted you to be comfortable.”
You nodded slightly and went to freshen up. After changing into something simple, you came out, hair still slightly damp, exhaustion finally settling in your body.
Suha was sitting on the edge of the bed, fingers nervously intertwined.
“You should sit,” she said.
You didn’t. Instead, you walked toward her slowly. “I’m hungry first.”
She blinked. “What?”
You gave a small, tired look. “I said I’m hungry. Please.”
For a second, Suha almost smiled—but it didn’t reach her eyes.
“Okay… I’ll get something for you,” she said quickly, standing up. “Just… after that, I need to talk to you about something important.”
You leaned slightly against the wall, arms folded. “Can’t it wait? I just landed, Suha.”
Her hands tightened together “No… it can’t.”
You walked into the dining area like you hadn’t eaten properly in hours—because you hadn’t. The food was already laid out, simple but warm. And that was enough. You pulled the chair and sat down without overthinking anything.
Within seconds, you were eating—fast, a little messy, completely unbothered. It felt… normal. For the first time since you arrived. Across the table, Suha let out a small giggle, watching you.
“You really haven’t changed,” she said softly, almost fondly.
You didn’t stop eating. “Food doesn’t wait for manners.”
Before Suha could respond, a chair scraped sharply from the other side of the table. The atmosphere shifted instantly. Jeon Jungkook sat down, glancing at the table—and then at you. His eyes narrowed slightly.
“What is this?” he said coldly.
You paused mid-bite. His voice rose a little, sharper now. “Do you not know how to eat properly? I prefer hygiene.”
You slowly set your spoon down. Then looked at him. “I’m eating food,” you said simply. “Not performing for you.”
Suha froze. Jungkook leaned back slightly, scoffing under his breath like he couldn’t believe what he just heard.
“You’re very bold,” he muttered.
You didn’t look away. “You’re very rude.”
The air tightened instantly. Suha stood up quickly and said to you . “Stop. Don’t speak back like that—bad manners.”
Her voice was firm, but shaken. You finally looked at her.
“Then he should also learn manners,” you said quietly.
Suha let out a small breath and reached for a napkin, carefully wiping your mouth
She turned toward him.
“Jungkook, I’ll serve you,” she said softly, already reaching for his plate.
He didn’t even look at the food. His jaw tightened slightly as he pushed his chair back.
“I’ll eat outside,” he said flatly.
Suha froze. “Outside?”
His eyes flicked briefly toward the table—toward you—then away.
“Some people… make food look gross today.”
You slowed your eating for half a second… then continued anyway, expression unchanged. If he wanted a reaction, you weren’t giving him one. Jungkook stood up, already done with the conversation, and walked toward the door.
Suha quickly followed him.
“Honey,” she called softly, adjusting his coat as he reached the door. “She’s young… I’ll teach her. Just don’t be rude like this.”
Her fingers lingered on his sleeve, trying to soften him. For a moment, she leaned in, trying to kiss him.
But he didn’t stop. He simply stepped away—cold, detached—pulling the door open. The kiss never landed. Suha froze mid-air, her hand slowly falling back to her side. Jungkook didn’t look back. The door closed behind him.
Night had settled over the house, wrapping everything in a quiet, almost suffocating calm. Jeon Jungkook came home later than usual.
Then he noticed the movement in the garden. A small figure sitting near the plants, under the soft glow of the garden light.
He frowned slightly and walked closer, “Who’s there?” he called out sharply.
The figure didn’t even flinch. Instead, a familiar voice came back casually.
“Relax.”
Jungkook stepped further—and paused. It was you. Sitting on the garden bench, completely unbothered, holding something tiny in your hands.
A small worm.
You tilted your head slightly, looking at it like it was the most interesting thing in the world.
“See, Mr. Grumpy,” you said softly, almost amused. “How cute he is.”
His expression changed instantly.
“What are you doing?!” he shouted. “Put that down!”
You blinked at him slowly “What?”
“That—” he pointed at your hand in disbelief. “That thing!”
You looked down at the worm, then back at him. “It’s just an earthworm,” you said calmly.
Jungkook’s face tightened. “That’s disgusting. Are you insane?”
You frowned slightly now, offended at his reaction more than the worm.
“Why are you shouting? It’s harmless. I found it in the garden,” you said. “It’s part of nature.”
“I don’t care what it is,” he snapped. “Just drop it.”
You looked at him for a second—then raised your chin a little stubbornly.
“Yaa,” you said firmly. “Don’t shout. I can shout too, you know.”
Silence fell between you two. Jungkook stared at you like he couldn’t believe what he was hearing. And you… just stood there, still holding the earthworm like it was the most normal thing in the world.
Jeon Jungkook exhaled sharply, clearly done with the situation.
“Just get lost,” he said flatly.
He turned and walked back inside, leaving the door open behind him for a second before it slowly closed.
Later that night…The house was dim again, softer now, almost pretending earlier chaos hadn’t happened. Jungkook had changed into more comfortable clothes and was sitting on the edge of the bed, expression unreadable, eyes distant. The room door opened quietly. Suha walked in she didn’t say anything at first. Instead, she went straight to him and sat beside him, gently resting her head on his shoulder.
There was silence. Then she finally spoke.
“…Will you sleep with her?”
Jungkook didn’t react immediately. His gaze stayed forward, as if her words were still processing in his mind.
Then slowly, he asked, “Did you talk to her?”
Suha shook her head slightly “Not yet.”
Jungkook leaned back slightly, jaw tightening—not anger, but something more complicated.
“If she agrees,” he said calmly, “I don’t have any problem.”
Suha looked up at him for a second, trying to read his expression. But he wasn’t looking at her. His thoughts were somewhere else entirely and he didn’t even realize it yet.
Morning light slipped into the house quietly, but the tension from the previous night hadn’t really gone anywhere. Jeon Jungkook came downstairs in a loose shirt, hair slightly messy, still carrying that cold, controlled expression.
He paused at the living room. You were there. Sitting on the sofa, legs tucked slightly to one side, fully focused on a laptop placed on your lap.
His eyes narrowed “That’s my laptop,” he said flatly.
Without even looking up, you responded . “Yeah, yeah, Mr. Grumpy,” you muttered. “Mine is dead. I’m just checking if my name is in the license list.”
He frowned “What license?”
You tilted your head a little, like it was obvious. “Oh.” You went back to the screen. “I’m an Obstetrician-Gynecologist.”
That actually made him stop for a second. His expression shifted—not soft, but surprised. Like he hadn’t expected that answer at all. His eyes stayed on you for a moment longer than usual. Then, as if resetting himself, he scoffed lightly.
“I’ve never seen an Obstetrician-Gynecologist this unhygienic,” he said coldly.
Your fingers paused on the keyboard. Slowly, you looked up again.
“…Excuse me?”
You stood up from the sofa and took a small step closer. On instinct, you rose slightly onto your toes, trying to match his height as much as possible.
“I’m way more hygienic than you,” you said firmly, eyes locked on his. The distance between you two suddenly felt too small. Too close. Jungkook didn’t move back. He just looked down at you, expression unreadable—but his focus had shifted completely.
Before the moment could stretch further— A voice cut in.
“What happened?”
Suha stood at the edge of the room, looking between both of you in confusion. The tension broke slightly. You dropped back onto your feet properly and turned your head.
“This man has no manners,” you said simply, pointing slightly in his direction.
Jungkook scoffed immediately “Look who’s speaking,” he shot back.
Suha’s eyes widened slightly “Please stop,” she said quickly, stepping forward. “Both of you—just calm down.”
But neither of you looked particularly interested in calming down.
Evening settled differently in the house—quieter, heavier, like it was holding back something unsaid. Jeon Jungkook was at his office . Back at home, you and Suha sat in the living room. The atmosphere wasn’t tense this time… just uncomfortable in a slower way.
Suha kept fidgeting with her fingers. She looked like she had been holding something in for a long time. Finally, she spoke.
“…You know,” she started softly, eyes down, “it’s been two years of our marriage. Still we don’t have a child.”
You looked at her, expression neutral, waiting. Suha swallowed and continued.
“We tried… but it’s not happening. His family… they want his blood. His heir.”
You leaned slightly forward, resting your elbows on your knees.
“Get to the point,” you said calmly.
Suha hesitated. Her voice dropped lower.
“I need your help.”
“I’ll help,” you said calmly "But tell me what kind of help.”
Suha’s fingers curled together in her lap. Her voice came out quieter this time.
“…I want you to sleep with him ,” she said slowly.
You just stared at her. Long enough that Suha’s confidence started to fade.
You finally exhaled, shaking your head slightly. “Are you mad?” you said firmly. “He’s your husband. Why would I do that?”
Suha’s lips pressed together, her eyes already getting glossy. She quickly reached for your hand, desperation slipping into her voice.
“I’ll help you open your hospital here,” she said fast. “In Korea. I’ll support you fully. Whatever you want.”
You pulled your hand back slightly, frowning. “Do you think I’m greedy?” you asked, voice sharper now. “You think this is about money or opportunities?”
Suha shook her head immediately, Her emotions spilled over before she could control them. Tears slipped down her cheeks as she covered her face briefly.
“Don’t you want me to be a mother?” she asked, voice shaking. “Don’t you understand how it feels? Every day… every day I feel like I’m failing.”
You asked “Do you love him?”
Suha hesitated… then nodded “…Yes.”
You watched her for a moment, then asked the next question carefully.
“Does he love you?”
Her eyes dropped instantly.
“I don’t know,” she whispered. “He never said it. He never kissed me… he never even calls me by nicknames.”
you spoke “Okay. I’ve decided.”
Suha looked up quickly, hope and fear mixing in her expression.
“I agree,” you said.
Her face brightened for a second—
“But,” you added immediately, “I’ll perform surrogacy.”
Suha froze. “No—no, that’s unsafe,” she said quickly, shaking her head. “It’s risky for you. I can’t let you do that.”
“It’s safe,” you said firmly.
Suha stood up slightly, panic rising. “No, no—this is not something you should just decide like this—”
You raised a hand, stopping her gently “Okay. Don’t panic. We’ll go to a doctor first. We’ll check if my body is even fit for surrogacy. If everything is okay, then we proceed properly. And if he refuses later… then we’ll see.”
Suha stared at you, breathing uneven, still emotional—but slowly calming down as your logic settled in.
The hospital room was quiet, smelling faintly of antiseptic and paper files. You sat on the chair while Suha sat beside you, both of you waiting as the doctor flipped through your reports.
After a moment, the doctor looked up, expression professional but serious.
“Miss y/n ,” she began calmly, “I need to explain this clearly.”
You nodded slightly.
“We ran all the required tests for surrogacy preparation. That includes hormonal injections and uterine support treatment.”
She paused, checking your file again. “But your body is not suitable for that procedure right now. The injections used in surrogacy preparation are quite strong. In your case, your body may not tolerate them well. It increases the risk of complications, including miscarriage.”
The word hit the room sharply. Your fingers curled slightly on your lap.
The doctor noticed and softened her tone. “But I want to be clear—you are not infertile. Your reports show you are medically capable of a normal pregnancy. It is just the artificial support process that is risky for you.”
Suha immediately spoke, worried.
“So… she can still become pregnant normally?”
“Yes,” the doctor nodded. “Naturally, she can. But she should avoid unnecessary medical stress.”
You didn’t say anything at first. But inside, one thing stuck louder than everything else.
Miscarriage.
You hated that word. It felt too heavy. Too final. Too cruel.
Outside the hospital…
Suha turned to you immediately, eyes full of urgency and hope.
“So… what’s your decision?”
You looked at her for a long moment. Then spoke quietly.
“I agree,” you said. “I will sleep with him.”
For a second, Suha froze. Then relief broke through her face as she stepped forward and hugged you tightly.
“Oh my God… thank you,” she whispered. “Thank you so much.”
You stood still in her arms.
Eyes open. Face unreadable. And somewhere deep down… you already knew nothing after this would stay simple.
