Summary: Naruto always left on a secret mission once a year for a whole month. A curious Hinata finally had enough and followed him to an underground house. A house she finds herself trapped in, with a dark Naruto.

The day was finally upon her and Hinata was ready. She wanted to know exactly what Naruto was up to and why he'd run away for nearly a month. After he had kissed her goodbye and waved at her she had given him a head start before following. Hinata had many ideas that floated around her little brain but she couldn't pinpoint which one was true. At this point, she had to figure it out or she'd go insane. Her imagination was running wild. How could he just say 'It's an important mission' and expect her to sit silently? He would disappear once a year for a whole month. It was always the same month. So what was he doing? What was this secret mission, that even she couldn't know about it?

Hinata could only follow Naruto as he walked alone into the woods. After a while, to Hinata's utter surprise he had met up with Karin, of all people. It was easy for Hinata to follow the two because Karin had complained about the whole thing. It was evident that Karin was not too happy about their mission. Luckily, with a little help from Choji giving her pills that could easily mask her chakra and Karin's lack of enthusiasm to be apart of whatever they were doing, it was rather easy to track the two.

Each step they took made Hinata's heart thump rapidly. Hinata couldn't understand why they took this trip once a year. She also wasn't made aware that Karin was apart of the trip. Okay, so maybe she is being a little childish. They are ninjas and they all have their secret missions, but no one in the village knew what she was talking about. Sakura shrugged it off and Kakashi told her there was nothing to worry about. Everyone else looked at her like she was crazy. Of course...talking to Ino did not help her imagination, but Ino just likes to start drama. Naruto wouldn't cheat on her.

She couldn't help the thought of Karin and Naruto doing naughty things together. Hinata slapped her cheeks a few times, 'She's his cousin! Stop that!'

With a shake of her head Hinata held onto her backpack strap tightly as she scurried to catch up to the pair. They had been traveling for a few days. Deep within the woods, they weren't too far off from Konoha but it was a good distance before they had stopped at a large rock.

Hinata hid in bushes eyeing the two. Naruto had turned to say something to Karin, causing her to scoff.

The rock slid to the side after a few hand signs. The two dipped down inside and the rock began to move back into place. Hinata breathed deeply before rushing forward. She slipped right on in, the rock blocking the light from behind her.

"Okay," She whispered to herself. Her feet carried her down the steps to a metal door, it was slightly cracked open allowing some light to peek out. Gently she pushed the door open, her eyes were met with a long hallway. It had seemed that Hinata had stepped into a large house.

Hinata's mind began to race with more wild ideas. She was going to confront Naruto about this little sweet escape. How dare he stay in an underground home with Karin! all these years he was playing house with her.

Hinata felt tears at the brink of spilling. She was going to give him a piece of her mind. Hinata walked deeper into the house with her fist balled up. She opened some doors to look inside of them, one of the rooms looked like their bedroom. Hinata walked in to inspect the room, her hand slowly ran on the blanket, that was just like theirs at home. Next to the bed was a picture of her and Naruto on their wedding day. Hinata picked it up staring at it, how could he keep this here when he was with another woman? Her fingers brushed off a bit of dust on it. Her finger traced the smile on his face. How could he do this to her? And with his cousin?! Hinata sighed setting the picture down, her hand lingering on it longer than she would admit. Why couldn't he just tell her he didn't love her anymore? But most importantly why did he keep a picture of them in a room that looked like an exact copy of their room?

A loud clanging noise rang throughout the house. Hinata jumped at the sound, it almost sounded like chains. Quickly Hinata rushed out the room, she caught a glimpse of Karin and dipped her head back inside. At the crack, she was able to see her leaving out the way they came.

Why was she leaving?

Hinata heard the loud chains again and looked down the hall to a large door. As she got closer to the door the clashing of metal became louder. Hinata pushed this heavy door open to reveal a dark stone path with a bit of light at the end, it veered off to the right. With a steady hand on the wall, Hinata creeps into the darkness. She heard Naruto muttering to himself and breathing loudly. He sounded like he was in pain, now and again he'd release a shaky breath. Hinata stood at the end of the hall not looking in yet. She wasn't sure what she would reveal to herself. She wasn't sure if she was ready.

The chains clanked together again as Naruto groaned.

Hinata held her breath, she leaned forward peeking around the corner, in the middle of the floor was Naruto. He had chains all around him. On his right and left wrist, the chains pulled his arms apart. He had chains on his ankles and a chain on his neck. He only wore his orange pants as he sweats from every pore. His eyes were closed tight in a fit of concentration. He groaned again, his body twitching oddly as if someone had shocked him.

Naruto inhaled and exhaled slowly, he was standing upright with his head leaned back. He let his head fall with a deep exhale.

"Naruto..?"

Naruto's head snapped up at her voice, his eyes flying open revealing their demonic red form.

"Hinata..what are you doing here!?" His voice trembled in fear and a twisted snarl rippled across his lips before disappearing as quickly as it came.

"Naruto what's going on?" Hinata stepped closer, she wasn't afraid of Naruto, even if his eyes were changed. Anything he was going through she would understand because she loved him.

"DON'T!" Naruto snapped towards her.

"Naruto please..." Hinata stood in front of him now, her bottom lip trembling.

Naruto closed his eyes and his back arched, a loud growl was released making Hinata's stomach drop.

"Hinata! PLEASE GET OUT OF HERE!" he cried in pain, his hands gripped the chains tightly.

"Naruto!" Hinata cried, seeing him in pain only hurt her. How could she help him? That's all she wanted. There was a loud snap as Naruto bent backward, a drawn-out groan was released and then he was still. His body dangled with only the chains holding him up. He was silent.

With wide eyes Hinata put a hand to Naruto's neck, checking his pulse. She let a sigh go. He was still alive.

"UUUUUHHH! RUN HINATA" Naruto gasped loudly.

Hinata jumped back as Naruto's neck whipped back, his eyes slowly opened to reveal the deep depths of black. The whiskers that Hinata had adored so much were just as black as his eyes. His body relaxed.

"Hinata..." he smirked. "You came to visit me?" His voice had changed drastically. It sounded like a demon version of her love.

"Naruto..?" Hinata took a few steps backward until she met the wall.

"In the flesh." He laughed

Hinata let her eyes wander.

"W-what's..g-going on N-naruto.." she bit her lip to stop it from quivering, the room suddenly felt colder.

"This..?"He moved his fist around jingling the chains."Just one of the ways your Naruto could think of keeping me here, but now you are here! I can't wait to enjoy our month together!"

"M-month, w-what are you t-talking a-about?"

"oh! You must not know. You and I are trapped here! I mean judging the fact that Karin had already left and sealed this place." Naruto's smile pulled back into a wide grin. His sharp canines being revealed to an already scared Hinata.

"A-a month? "

"Yeah- there's no way out so it's just you...and me...and thirty-one days to ourselves...happy honeymoon."

Hinata held her breath making Naruto laugh. Hinata felt that her time with Naruto would not be the honeymoon that she had dreamed of. This house was a prison to hold him here for a reason, one she was slowly starting to understand. Hinata swallowed the lump in her throat. Her fingers itching the wall in fear.

"Let me out of these chains baby." He wiggled his wrist again. However, the girl was frozen in place, unable to move.

Naruto's smile faded as he stared at her, "Hinata, fucking let me out."

Hinata slowly shook her head left and right, Naruto would never curse at her. He would also never speak to her in such a dirty fashion. The dark Naruto glared at her.

"HINATA!" he jerked forward making the girl push back into the wall. Her body began to tremble.

"Okay... Hinata, " he laughed abruptly, "I'm just messing around Hinata! It's me come on let me out !" he jumped forward again snarling, realizing the girl would not budge.

Hinata slid her left foot, catching the boy's attention.

"Hinata..." He said with a warning.

He watched as Hinata slid across the stone wall, their eyes never leaving each other. The way he stared at her made her uncomfortable.

"HINATA! I SWEAR I WILL FUCK THE SHIT OUT OF YOU!" Naruto began thrashing around wildly.

At this shocking statement, Hinata whipped around and ran, "HINATA YOU CAN'T RUN!"

Hinata pushed the door open running down the hall. Her legs wobbled as she climbed the steps.

"Ngh." Hinata pushed on the boulder, but it was for nothing. It would not budge no matter how hard she pushed on it. She even tried to use chakra. Activating her clan's eyes she was able to see the boulder was infused with chakra, the whole place was. She let out a frustrated cry as she slid down to sit on the steps. Her eyes returning to normal. She stared at the door below her, the only light coming from the hall.

To her surprise, the dark Naruto had gone silent.

She brought her knees up and put her face into her hands. There was only silence, but that was rudely disrupted.

"Hinataaa...!" Naruto called off in the distance.

Hinata began to cry. She was going to be stuck there for a month.

Being that she was stuck there, Hinata had explored the house. One of the doors she had found had led to some stairs. It led to a living room with a T.V. and some books. The living room had dust everywhere. There was also a kitchen, and all the ramen one could eat, along with real food in the large pantry.

The underground house had everything Naruto needed to stay there for a month and some change. She made herself something to eat and sat silently, listening to the thrashing of chains. Now and again Naruto would shout a slue of curse words and dirty things. Hinata couldn't even call him Naruto, he was nothing like the man she married. Hinata couldn't relax at all with him thrashing around and yelling. What would she do if he had gotten out, and what would he do if he got out? He had suggested what he would do but Hinata would not allow herself to think about it. His crude words made her queasy.

Hinata picked up a plate of food, but he was still Naruto.

"Naruto.." Hinata called as she walked into the stone room. She held the plate tightly.

"Hinata...welcome back!" He smiled. "Come to let me out?"

Hinata didn't speak to him as she walked up to him with the food.

"How am I suppose to eat?" He shifted around with a wave of his head.

Hinata picked up the spoon and gently blew on the contents.

"Not gonna talk to me huh?" He took the food that was offered to him. After she put it in his mouth he hummed. He opened his mouth with an 'Ahh', ready to receive more.

She kept feeding him in silence. Her eyes never looked at his and his eyes never left hers. After the bowl was empty Hinata took a step back.

"That was delicious..it's great having you here." Naruto leaned forward but Hinata was already walking away.

"HINATA, you can't just leave me here!" He jerked forward

"HINATA!" and then there was a loud clang, Hinata looked back at the raging Naruto. He stopped his movements, the chain giving way just a little. Naruto smiled looking at her. He balled his fist up and with a look of determination Naruto's fist shook as he pulled them towards himself. The chains began to shake violently. Naruto strained as his muscles tensed, and then one chain snapped.

Hinata gasped dropping the dish, allowing it to smash into a million pieces. Naruto strained more as the other chains snapped. Naruto's dark chuckle was all Hinata heard as she ran away, looking for a place to hide. Hiding somewhere was all she could do. Running around she frantically looked for safety as more chains were snapped. She decided to hide in the large pantry, tucked away in the corner. As soon as she scooted as far back as she could and shifted some food around she heard a slam.

"Hinataaaa" Naruto's sing-song voice was louder than before. He had broken out of his chains and was now looking for her. She was tucked inside the corner, hugging her legs tightly to herself. Luckily her chakra was hidden by The pills Choji had given her but they were wearing off by the minute. She would take another one but her bag was in the kitchen.

Tears streamed down her cheeks as she waited for Naruto. Her nostrils flared as she breathed in and out. The house was only but so big, sooner or later he'd find her. This thought made Hinata sniffle. The door flew open and Naruto in all his glory stood proudly. His red eyes searching for her in the dark pantry.

Hinata pressed her legs into herself trying to make her self smaller. Her eyes watched between the bags of food, she could see Naruto just a little bit.

"Baby, stop playing hide and seek." He whispered.

His eyes looked over the area and before he looked in her direction she ducked her head down. Her head was in her knees and she held her breath. A long minute went by with Hinata holding her breath, as soon as she heard the door shut, she released it. She was back in the darkness, trying to listen for Naruto. She heard his soft footsteps walk away. He couldn't sense her chakra but if the pills wore off she'd be found out. The backpack was just by the table. She would just have to get it.

On her hands and knees, she crawled towards the door. Her fingers shook as she grabbed the knob. With a soft twist, she opened the door just a crack. The light from the kitchen spilled into the pantry making her eyes flutter from the change.

She saw no one in sight. Leaning her head out just a bit she looked both ways. Her heart hammered in her chest, her eyes looking from side to side. Opening the door a bit more she waited and listened. There was a shift in noise above her and her neck snapped up to see red eyes staring down at her.

"Looking for me?" Naruto grinned on the ceiling.

"Ahhh!" Hinata let out an ear-piercing shriek and tossed the door open. She shot up and ran as quickly as she could, slipping and running into the wall. She fumbled with the door throwing it open as she rushed up the steps.

"Run, run, run, baby!" Naruto stood at the bottom of the steps watching her tumble.

She broke through the door shutting it behind her with a slam. She looked at her surroundings before running towards the exit. She had no plan and she had no idea where to go. She was trapped.

Hinata ran up the stairs slamming her palms on the boulder.

"Help me! help me please!" she called

"Hinata, trying to leave me so soon?"

Hinata looked over her shoulder to see the blonde standing at the bottom of the stairs, he looked up at her with a toothy grin.

"Ahh!" Hinata cried slamming on the boulder, even more, each step he took towards her made her slam even harder. His figure blocking the light casting a dark shadow over his face. The devil was coming for her and she was doomed.

Naruto grabbed Hinata by the ankle and dragged her down so he was towering over her while she laid on the steps. A hand placed at the side of her head.

Hinata had finally stopped screaming due to her throat going dry. Her lip trembled in fear. All she could do was stare up at the demon above her, a demon wearing her husband's skin. He pets the side of her face with the back of his hand, as she whimpered. He leaned down so they were but a breath apart.

"Gotcha."

Hinata let out a bubbling scream as Naruto laughed darkly. He stood up and grabbed her ankle dragging her down the stairs. Hinata flailed her arms wildly trying to find any grip to hold her from being in his clutches.

Naruto dragged her into the hall and shut the door behind him, her screams drowned out.

Not too far from the boulder, Karin was in a cabin enjoying a hot bath with sliced cucumbers on her eyes. The feeling of intense chakra made her jump up in the tub, the cucumbers slid right off into the water. She had a look of worry on her face, "Naruto...you really didn't hold him back at all this time." She sighed leaning back in the tub. The sealing should hold him in the house but if he is breaking the chains already then she was a bit worried. Any more and she'd have to call Sasuke. His chakra had calmed down, so that put her at ease. Karin let out a sigh," I don't get paid enough for this."
