"Haru, I'm heading out now." Rin informed as he finished putting on his shoes. "I'll be back soon, okay?" he said, turning around and looking down. He really worried about leaving Haru alone as he wondered what kind of mischief he would get up to.

He had a few things to pick up from the store; he had needed to go shopping for groceries for a while but had been putting them off. He had just made monster mash up meals out of whatever he had in the fridge.

However now he seriously needed to get food; if not he would starve as would Haru. And the last thing he wanted was to let his poor Haru suffer. They both needed their nutrients and Haru couldn't eat pickles or chocolate milk.

"Meow" was the reply from the black cat on the ground, staring up at the redhead with blank, ocean blue eyes. He waited patiently for the redhead to leave his eyes intense and patient. He would make sure to be extra careful this time so Rin wouldn't get suspicious; so playing the obedient card would fool him so he could sneak away.

"Be a good boy and watch the house, okay?" Rin told him as he knelt in front of the feline, raising his hand and scratching under his chin. As long as he didn't climb on the bed again or break anything; he could rest assured.

He smiled as he petted the small feline. He knew all Haru's sweet spots; all the areas in where it would make Haru the happiest. Which parts on his small furry body that would erupt the most purrs; the places that would feel best to him.

He knew Haru's body like a book; in both his feline form and his other form. He knew exactly how he liked it and how to make him happy; nobody could love him the way Rin did. He knew everything about Haru; all his turn on's, kinks, desires, fantasies, dreams and body language; there wasn't anything he didn't know about Haru.

A low purr emitted from cat before he quickly turned his head away. The redhead chuckled from his action. Even if Haru didn't admit it; he loved being babied like this and having Rin fawn over him. He was just too stubborn to admit it; but Rin loved that about him.

"You're so cute." he said, picking up Haru and placing a small kiss on the top of his furry head. He could kiss Haru all day long; he was just too cute. However he did prefer all the certain areas he could kiss when Haru transformed.

The black cat hissed softly before he jumped out of the young man's arms. He didn't want to be touched by him; he would never allow himself to feel such things. He hated the life he was forced to live with Rin and he would never accept that he was stuck this way.

The redhead smiled sadly but hid his inner pain from the cat. He only wished Haru would go back to the way he used to be; the Haru who loved affection and craved it like you would water or food.

"Well, guess I better get going." Rin announced as he stood up and walked to the door, opening it. If he waited any more they would be out of what he needed. There was nothing scarier than a 20 something man or woman when it came to bargain sales. They would rush to the stores in flocks and grab the first thing they fancied and snatch it up for themselves.

However his heart was still heavy at being rejected by Haru even after all this time. However he had built a tolerance to his abuse in his cat form and simply patched himself off. He would never let Haru see how much it hurt; because he would never understand why.

He didn't remember after all; he didn't remember any of it. But that wasn't Haru's fault no matter how unfair it was or how much it hurt Rin to accept it; but he would keep waiting patiently till that day came. When he finally got the boy he loved back who would smile at him with his big blue eyes and take everything he gave him.

"Bye, Haru." he said to the cat before he walked out, closing and locking the door behind him. He had made sure to check everywhere to see that it was locked up tight. He couldn't risk him getting out and trying to leave again.

Haru's ears twitched as he listened to the sound of his owner's footsteps fade. He had make sure he was far enough away that he would notice what he was up to; couldn't be too careful after all.

When they were gone completely, the black cat meowed before he turned around and walked into the living room of the apartment. He didn't plan on staying here a second longer if he had anything to do about it.

He headed towards a high shelf. Laying on it was a medium-sized, black velvet box. A low, rumbling noise vibrated through Haru's throat as he stared at the box. He glared intently at it a small growl growing from the back of his throat.

That box was his only ticket out of here; he didn't want to remain trapped here forever. He didn't plan on being Rin's prisoner forever trapped in this damn form like this. he would escape him and he would get free; he wasn't going to stay his prisoner a second longer.

He took a few steps back and planted his paws firmly on the floor. Then the black cat ran at full speed towards the shelf. To anyone else witnessing this he looked like a small furry black dart that just lunged itself at the shelf faster than anyone could spot him.

He jumped, his claws latching onto the wood of the edge shelf. With some struggling and a momentary situation of just hanging there, Haru lifted himself up until his whole body was on the shelf. Briefly he looked behind him at the fall he could have suffered if he hadn't managed to climb up; he shivered at the idea.

He let out a small sigh feeling relived that he had been fortunate enough not to fall; or Rin would become suspicious as to how he got hurt when he returned. If that happened he would hide the box somewhere else and it would take an eternity to try and find it again.

He shook his head crossly; now was not the time to be pondering on such things; he had more pressing matters at hand right now. Turning his attention to the box, the feline got behind it. He placed his paws on the front of it, his claws sticking into the cracks of the top lid.

Haru meowed as he tried to pull open the lid. It took a few times and he nearly broke a claw, but the black cat eventually flipped the lid open. He quickly checked his paws before he looked at the contents; he didn't want to hurt himself after all.

His tail swished side-to-side when he saw what was in the box. It was a necklace with a golden chain and a charm of a white, crescent moon was hanging in the front of it. White beads that resembled pearls were laced either side of the moon around the lower part.

Using his teeth, he held the item in his mouth. Then he jumped down from the shelf, landing gracefully on the floor. The charm shining from the light of the moon that was coming through the window.

Eventually a silver light erupted from the necklace and surrounded the small black cat. His blue eyes glowed as the light grew brighter and his body began to change; at last he was able to revert back from this cursed form.

He was no longer weak and could escape Rin; he didn't have to remain his submissive obedient pet a second longer. He could finally be rid of him and find freedom; no more being trapped in this damn house.

A couple of hours later

"Haru, I'm back." Rin announced as he walked into his apartment, grocery bags in his hands. He sighed with relief as he placed them down on the floor; they had been heavy due to the amount of shopping he had bought.

He had bought a lot mind you; he had to restock on everything they needed. Plus he had seen a few discount sales that he couldn't resist getting; so he had taken a lot longer than he meant to.

However thanks to previous years of training as a swimmer in high school; his body was able to carry a lot of weight. His stamina and endurance levels were higher than most people his age. However that didn't mean he was a superhero; he still got drained and suffered pain and exhaustion like any other person; it just took a lot to get there.

Once he recovered he started looking around the house for his beloved pet "Guess what! The store was having a on mackerel. I figured that since you've been so good these past couple of weeks, I thought I would..." he trailed off when he realized how quiet it was.

"Haru?" he called out, setting the bags down. Had he gotten bored and gone to play? Maybe he fell asleep on the bed again; he knew he wasn't allowed to do that when he wasn't home.

No reply came. Walking into the living room, the redhead looked around and saw no sign of the feline. This raised suspicion as Haru was usually very vocal and made himself known as soon as Rin came home.

"Haru, if you're playing some kind of joke, it's not funny" Rin scolded sharply. He knew better than to make him worry. He was a strictly trained house cat and not allowed to leave the house because he was where Rin couldn't see him or find him.

Still, no sound that resembled a meow was heard. Then, out of the corner of his eye, Rin saw something that made his breath hitch. The velvet box on the high shelf was wide open, empty.

He had thought he had hidden it well from Haru ensuring that he wouldn't find it again. It seemed while he went away Haru had picked up the bad habit of sneaking around.

"I see..." was all he said, a slightly dark look entering his red eyes. "So you're trying to run away again, huh?" he growled darkly. How many times did he have to teach Haru not to leave his side.

He tried to be patient and understanding; knowing how hard it was for Haru to always be stuck in the house. But its not like he had a choice; if he let him out he would run away. If he ran away someone else would take him; and the idea of someone else touching Haru, of loving Haru made his blood boil and his chest tighten.

He placed the shopping down on the floor and exited the house anger and sadness in his eyes. Just how many times was Haru going to try and leave him? Didn't he know how much he loved him.

He showered Haru with kisses and affection when he was a cat. He was patient despite the fact Haru would scratch him or avoid him. God knows he got lonely when Haru avoided him; yet sometimes was cuddle up with him on the bed.

Everything he did it was to make Haru happy. He knew keeping him locked up wasn't exactly fair but it was the only way he could think of to keep him safe. He just couldn't bare losing him again.

Meanwhile in park

Panting heavily, Haru sat down on the bench of the park he had run to, getting a good amount of distance from Rin's apartment. He ran a hand through his raven black hair. His body felt heavy and weak; he hadn't eaten yet today so his body was losing strength fast and that wasn't good.

He had worked up quite a sweat running here. He hadn't had that much exercise in a while so his body was quite exhausted. Sadly, he didn't have any money to buy a drink to hydrate himself as well as something sweet for an energy boost.

'Hopefully, he still hasn't come home yet.' he thought to himself. 'Damn him, keeping me as his pet for this long.' he frowned. When he first met Rin he had been so happy; he felt loved and like he could trust him. He never treated him badly and even bought him clothes or presents.

However, later on Rin changed; he never let him leave the house or let other people touch him. He got very protective over him and every time he finally was reverted; he made sure to train him so he would remain obedient.

His hand trailed up to the necklace around his neck and gripping the charm tightly. 'Am I going to be cursed as a cat forever?' he mentally questioned, his ocean blue eyes becoming slightly downcast.

He knew no other method to being able to be permanently human. He knew Rin did but he was keeping it a secret so he wouldn't be able to leave him. But so far the only method Haru could find was the necklace.

Haru sighed and leaned back into the bench, staring up at the moon. It was still daytime so the true radiance of the moon was not shown; but it was still nice to look at from afar.

He then closed his eyes, listening to all the small sounds that were around. He didn't know how long it was, but he soon heard the sound of footsteps fast approaching. However little did he know that they were a warning sign that he should escape immediately.

"Haru..." a cold voice said from behind him. He could hear the rage and hurt in Rin's voice. He only used this voice when he was serious and in psycho mode; this meant Haru was in trouble.

The raven-haired boy's eyes snapped open when he heard his name being called from the very familiar voice. Quickly standing up, Haru soon found a pair of lips against his own. He moved to fast for Haru to resist so he had no choice but to simply let it happen.

A hand gripped his face pulling him towards the Maroon haired boys face; he clicked his teeth as he was pulled closer and forced into a kiss. "Mmh!" he moaned as Rin kissed him. God he hated how Rin could control him with his sexuality and seduction like this.

As he fought against him Rin forced his mouth open with his tongue intertwining his own with Haru's. The latter moaned again as the latter eloped him in a passionate and dominant kiss.

Rin knew every sensitive area of his body; all his kinks, his turn on's and his weaknesses. He could control him to the point he had no way of fighting back or resisting his urges. He would submit himself completely to Rin.

He tried to pull away, but the redhead wound his arms around the shorter boy and was holding him close. He had no intention of letting Haru go; not now, not ever. He would hold onto him till the end of time.

Haru squeezed his eyes shut, not kissing him back. He would never submit to Rin and he knew that by not returning his affection it would hurt Rin; so he used this to get back at him. To hurt him via his emotions so he understood some of his pain at being held prisoner by him.

Suddenly, he felt the chain of the necklace slip from his neck. A weight lifted from his body as the accessory was removed from his person; you would have never guessed such a beautiful piece of jewellery would weigh so much.

"I have to say..." Rin began as he pulled away from the raven-haired boy, the necklace in his hand. "This is the farthest you've ever gotten." he remarked, starting down at the black cat.

Haru had certainly gotten better at finding places to hide but Rin was good at reading Haru. He knew how to read him like a book; so he could predict everywhere the raven haired boy would try to hide.

"Too bad this is as far as you'll ever get." he added, his mouth curling back into a smirk, flashing his shark-like teeth. He wouldn't let Haru escape him again; he was his forever and he would remind Haru of that until he understood.

He had already lost him once before and he wasn't going to let it happen again. He knew Haru didn't remember but that was ok; because he would make him remember with his body.

He would continue loving Haru's body until he did remember what he meant to him. Every curve, every line, every muscle, ever inch of him he would love; he would kiss, lick, bite, suck and tease ever inch of him until he remembered.

Haru hissed as he glared up at the redhead. He turned around, planning on running away. He wasn't going back to that house and staying locked up unable to enjoy the outside world.

"No, you don't!" the redhead retorted coldly. Rin's arm shot out, grabbing the feline by the back of his neck. He didn't grab him hard mind you; he held him the similar way a mother cat would do when carrying him.

Haru hissed as he tried to get out of the young man's grip, scratching and biting his hand. The latter just winced a little but was more than used to Haru's tantrums. He had developed a semi immunity to Haru's attacks.

"It's useless." the redhead told him, lifting him up closer to his face. The small black cat glared back at him with his cerulean blue eyes intently; anger glowering from them. It was hard not to be upset when someone you loved so dearly and someone who once loved you just as much now hated you more than anything.

"I've gotten use to your scratches and bites. Unless you're wearing the necklace, you're nothing more than a defenseless kitten." he remarked, placing said necklace around his neck. He would have to hide it in the cellar in the safe down that he discovered down there; he never thought he would need it but now he did.

The black cat continued to bite his hand, even after Rin was now holding him in his arms. He struggled angrily trying to get free of his grasp. He pierced Rin's skin harshly as he tore at his hand with teeth and claws.

He wanted to hurt him so he could convey his anger, sadness and frustration of being held prisoner against his will by Rin. He didn't care if Rin cried or hated him; he didn't care if he sulked; as long as he knew and understood how he felt.

"Speaking of which..." the young man started to say, one of his hands placing itself on Haru's head and began to rub it. The latter stilled and felt himself beginning to purr as his body began to betray him to the affection he was receiving.

Rin looked down at him pouting crossly and pinching Haru's ear a little as punishment. "Bad kitty, trying to run away again. And after I've been so nice to you…" Rin scolded hurtfully. Yes, he was firm with Haru and teased him; however, he was only protective and obsessive because he didn't want to lose him.

He couldn't bear to lose Haru again; it already hurt so much last time. Watching the light leave his eyes and the blood seep from him was something that had broken Rin internally. The tears he had shed that day had been enough to fill oceans with his mourning; they wouldn't stop and he couldn't stop shaking or screaming as he clung to him.

Many generations later after being reborn with his memories; he had found Haru only he was sealed in his current form. He had sworn since that day he would never let Haru go again and would forever keep him by his side no matter what. Even if it meant Haru hated him he would never let him go ever again; because he couldn't lose him like he did before.

Rin closed his eyes sighing sadly. Haru was here in his arms; he shouldn't keep dwelling on the past so much anymore. "…But, lucky for you, I'm in a good mood today. So, I'll overlook this incident just this once."

Haru finally gave on trying to escape and stilled. Knowing that he wasn't going to be injured or punished for running away was a relief; he had been terrified as to what Rin was going to do.

"You should know by now that I don't intend to ever let you go." Rin told him. "After all..." he smiled. "You are my cute, little cat." He belonged to him body, soul and heart; it had been this way since the beginning and it was absolute.

The black cat didn't reply, his head bowed down. He was forever chained to Rin as much as he may hate it; because Rin loved him too much to let go. No matter how hard he tried he couldn't fight against his fate.
