"Yao-san, why are you still up?" Japan asked yawning loudly as he shuffled across the living room where China was sitting on the couch, laptop in his lap and the lights on but low. The chinese nation looked up and smiled softly at the sight of his tired wife.

"I can't sleep, I'm too itchy. And my back is killing me, plus I'm just too keyed up to even humor sleeping." China replied on a sigh as he moved a hand up rubbing the back of his neck then smiled apologetically. "Duìbùqǐ. If I'm keeping you up I apologize. But look at this! I didn't even know this much when you were pregnant -aru!"

"Nani?" Japan sat next to his husband looking at the computer screen curiously, his brown eyes warm as he looked and then met China's excited, more than awake eyes. "What is it?"

"It says in the fifth month I'm going to get bigger quicker cause the baby is hitting a birth spurt and I'm going to start having back pain because of the growing -aru. My sciatic nerve is going to feel the pressure too, which is gonna be uncomfortable but I guess I need to figure out a comfortable sleeping arrangement." He smiled at Japan and scrolled down on the screen. "There's going to also be abdominal weight and, if I have too, I can use a pregnancy girdle -aru."

"You've been looking into a lot!" Japan finally said in an awed tone as he then yawned before he could help it or stop it. He leaned his head on China's shoulder and, subconsciously, reached out stroking the soft curve of China's stomach.

"I want too -aru. This is our baby, our little girl and I also find myself curious about it cause I am the pregnant one this time -aru." China replied with a soft chuckle and covered Japan's hand when it stopped right in the center of his stomach. "I can't wait until she starts moving -aru!"

"Neither can I." Japan smiled lightly patting China's stomach in a comforting pattern, one he'd done for the past five months and China smiled. The past five months have passed in a blur it felt- at least to China. He loved the baby growing inside him with such an intensity it was like he was seeing and feeling what Japan felt when he was pregnant with Xiong and Chiyo.

"I was thinking about names -aru." China finally said after a moment as he smiled softly, looking at his wife who raised a brow curiously. "I kind of like the names Aaliyah and Zhen -aru."
Japan smiled wide then despite how sleepy he looked and stroked China's stomach softly. "Those are beautiful names, Yao-san."

"I know and that's why it's so hard to choose which one I want to name the baby -aru." China sighed out as if torn when he looked at the clock then looked at Japan. "It's midnight, -aru. You should go to bed."

"Come with me." Japan replied instantly as his eyes met China's golden-brown ones and the Chinese man sighed shutting the laptop and standing up groaning, rubbing the small of his back and Japan hopped up.

"I'm fine -aru. Let's go to bed now, shi?" China held a hand out smiling as Japan took it, holding it tight squeezing it softly. They walked from the living room area, China already waddling lightly like a little penguin.

Japan fought the urge to laugh and point it out as he held his husbands hand, walking down the hall to their bedroom and he wondered briefly if China would be okay laying on the floor like usual. He looked at China's large stomach and wondered if his mother intuition was right and it was a girl even if Japan felt like it would be a boy again. When they entered the bedroom China lifted his shirt, Japan grabbing the prescribed lotion for him and squirted some on his palm, not a lot, just enough for a thin layer and rubbed it on his stomach, noting the loud sigh of relief.

"Was it itching that bad, Yao-san? "Japan asked looking up at him from under his lashes but with surprise. He didn't think his husband was itching that bad and felt just a little bad as China pulled his hair down, dark locks spilling around his shoulders and Japan hoped then that their child had that color, not his black colored locks but China's rich dark brown ones.

"Shi! But I appreciate you putting it on my belly -aru." China pecked Japan's lips happily as he then laid back, wiggling under the blankets and Japan got up, walked across the room flicking the lights off and then walked back to the bed sliding under the covers next to China who was sighing. "I really think it'll be a girl -aru."

"I don't know. I feel like it'll be a boy." Japan mused as his hand rested on China's large stomach and his head on his chest, China's arm going around him and holding him close as the edges of his hair were played with the tips of his fingers.

"Nope~ It'll be a girl -aru! Baba's intuition is never wrong~" China chirped cheerfully when a yawn seemed to burst out of him out of nowhere. He felt mild pressure on his lower back, more so than normal, but ignored it as he closed his eyes. "I'm so tired now -aru!"

"Well now that you're actually laying in bed it's normal~" Japan playfully said but noticed China's discomfort and sat up just a bit. "Yao?"

"I'm fine -aru." China sighed but rolled onto his side to relieve the pressure. "Let's just sleep and the discomfort will be gone. But we need to choose a name in the morning -aru."

"Why? We have four more months before the baby is here to choose." Japan softly said when China didn't answer and he looked at his husband. "Right?"

"I don't know. I feel like something bad is going to happen -aru." China mumbled as he began to drift off and Japan held his husband with a gentle squeeze. He was sure the other was over reacting! Sure, China had the flue-like symptoms a few days ago and they went to the doctor and he was perfectly fine but lately those symptoms remained even if they were assured China and the baby were healthy as a horse.

"It'll be alright. Don't worry." Japan kissed his chest softly then squeezed him softly once more. "I'm going to visit Italy in the morning to see his pregnancy so far. He invited me over and I am taking Chiyo to go play. Okay, Yao-san?" Silence greeted him and he blinked. "Yao-san?" He looked up and sighed at the slack, pale sleeping face of his husband when he felt something underneath his hand on China's stomach. A mute, faint thump like a kick or punch, which should be impossible.

"Ai shiteru, Yao-san. I hope you sleep good." Japan murmured sighing and, eventually, felt himself drift off to sleep.

"You're still in bed?" China opened his eyes tiredly, his back throbbing and he had dull aches in his stomach and he felt like he was dying with flue symptoms. He looked up at Japan's concerned face, in his brown eyes, but China wanted to reach out and touch his wife. "Are you truly alright, Yao-san?"

"I'm fine, my back just hurts -aru. I'm going to take a hot bath but I need help getting up -aru." China looked sheepish as he saw China's concerned little smile as he then helped China sit up who did so with a low groan. He rubbed his lower back that pierced sharply and stood up swaying lightly as he was ushered to the bathroom, his whole body hurting as he sat on the toilet to tired to stand up much more as Japan began filling the bath. The Japanese nation turned to his husband, touching his forehead softly.

"You're burning up!" Japan noted as he then caressed China's cheek softly as he frowned. "I'm worried, Yao-san. You've been like this for a few days now but it's like it's all cresting right now and I feel bad about leaving-"

"It's fine. I'll be fine, the baby will be fine. We'll both be here, waiting for you and Chiyo and Xiong to come home -aru." China assured him as he lifted his hand covering Japan's hand, pressing his hot cheek into his wife's cool hand. He felt something was wrong. Had to be. "I'll be right here waiting for you to come home, my precious Kiku-chan -aru." China smiled.

"Okay..." Japan breathed out, chest tight, not wanting to leave his husband's side then, squatting down to look into the tight drawn face, white almost with his cheeks flaming red with his fever. "I'll make the bath lukewarm, just enough to help your lower back but not enough to bring the temperature up. I'm going to call someone over to watch you while I'm at Italy-kun's home."

"You don't need to do that -aru!" China groaned as he let Japan fix the water up and helped the weak China get undressed. He sighed when he was sliding into the lukewarm water, his head falling back as his hair spilled out over the rim. "I'm perfectly fine on my own -aru."

"No!" Japan barked standing up and stroking any loose strands of hair away from China's forehead. "I'm not taking any chances with you being sickly!"

"If it makes you feel better -aru." China sighed shrugging when he felt a muted thump against his belly making him blink. "Is it possible to feel a baby kick at five months -aru?"

"Well you know Chiyo kicked a lot when he was in the womb but that's a second pregnancy. Though I don't think it's impossible to feel a baby kick at five months." Japan replied then smiled as he walked to the bathroom door, Chiyo shouting impatiently to go and he took a look at his husband, baby bump just barely skimming the surface of the water. "But I felt movement last night."

"Really -aru?" China looked surprised, sitting up right with a little difficulty and Japan nodded. He never could really get over how maternally feminine China looked with his pregnancy, skin soft with a gentle glow the past five months, his hair was silkier, eyes brighter and he was more energetic. Happier. He loved pregnant China, even finding sex with the pregnant elder strangely interesting to him but he knew it was just a new, open and softer feeling China.

"Really. Now, I have to go. I'll someone coming over soon, I promise." Japan promised as he then grabbed the door knob in his hand tight and smiled gently. "Ai shiteru."

"Wǒ ài nǐ, Kiku." China sighed as he slumped in the water, twitching at the pain. He kept his eyes shut as he listened to Chiyo shrieking excitedly and Xiong asking why he had to go along now but Japan's response was soft and the front door opened, all three shouting their respective I Love You's and the house was silent. He wondered, briefly, who Japan would get to come baby sit him and opened his eyes.

China shifted ever so barely with the pain gnawing at his back and soft, muted thumps against his hand. "Wǒ de gōngzhǔ." He sighed stroking his belly softly in time with the muted thumps and smiled to himself. Despite the pain of his body and the tiny bad feeling, he was happy to feel his baby happily moving and he felt excited for the next four months to be over so he couldn't finally see his baby.

He imagined so many times how she'd look, with his dark hair and Japan's brown eyes or Japan's black locks and his golden-brown. Basically, either a female version of Chiyo or Xiong. He hoped the baby would look more like Japan, praying for it, excited to have a tiny Japan again and maybe that's why, when he shifted, he felt a bubble of pain he'd never felt gasped at the suddenness of the pain that struck his lower half in waves and it was so intense he leaned over the rim of the tub and vomited on the floor. He managed to pull himself up through the pain, crying openly with sobs at how bad it was as he shrieked when the pain crested and died at ten minutes in between which was nowhere near enough. Sure yesterday he got intense aches but that was so long ago!

He hunched lightly, the urge to stop and push was so strong and Japan already left to Italy's. How freaking ironic could that be? How cliche was it that the one who knocked up someone left right as something tragically bad like labor starts. He wobbled to his bedroom, the contractions were painfully tight and hot, so unmistakable as he got to his and Japan's room when he felt something trickling down his leg. He reached down and when he looked at his fingers and saw purely colored, scarlet blood bright as a neon back at him smear that he paled. It reminded him of the story Italy said of his miscarriage but he was so much farther along and there was nothing wrong! The doctor assured them that he and their baby were fine!

"Ah!" He screamed at a painful slicing pain ricocheted through him and he fell to his knees, crawling forward. He saw his cellphone winking at him, like a cruel trick, each movement slow and filled with pain at the who entire suddenness of it.

He didn't understand why, maybe the throbs and back pain should have been sign number one the other day and how they continued long into last night and were incredibly, substantially, worse this morning. When he felt his phone in his hand he gasped pulling it to him and dialed for his doctor, who answered, and he rushed told him everything that was going on with the pain. He was assured an ambulance would be there and he hung up the phone. He rolled onto his back, his legs instinctively opening as blood smeared the inside of his thighs as he shuddered with tears rolling down to his temples.

"Please -aru! Please don't let my baby die!" China gasped to no one in particular as he touched the middle of his stomach, pain rushing and he felt more wetness.

He cringed as he sobbed not even bothering to cover his mouth as he did so and prayed Japan would come home. That their baby would be okay. He sobbed as he lifted his phone and without much hesitation texted the one person he hoped would actually come to the hospital until Japan received his message and he sobbed as he texted as the sound of sirens approached and he never felt happier to hear such a blissful sound.

"Just hang on, wǒ de gōngzhǔ, hang on." China gasped as he heard the ambulance coming closer and wondering why, at this moment, his life felt like it had taken the bad turn in some fanfiction or even a book or a stupid movie. He just held his stomach when the front door opened and cried when the EMT's came in asking questioned and he hoped, prayed, that the one he texted would be getting in contact with Japan any minute now. He just had to hope and pray right then.
