I also want to clarify that I'm practicing my English, I'm still learning, so excuse me for the mistakes.

Date A Prince

Part 1: The promise

"Ahhhgg..."

Complaints were inevitable, it seems that at the close of spring break, the welcome gift to a new school year was a morning nuisance, nothing perfect to start the day.

She knew where this pain came from, its causes and consequences, she knew them by heart and had experienced them several times, constantly.

"It's already seven past five..." said the grumpy girl as she looked at the time on her digital clock.

At least the pain in her belly had been better than her alarm, and much more annoying of course.

She sat in bed, but in doing so, she had a wet feeling in her butt and part of her legs, her thin fingers trembled and her mouth remained open, the shame of having pissed on the bed suddenly assaulted her, although that was not the reason.

"No... No... No... No... No, no, no..." she whispered as she lowered her head slightly and removed the sheets outside, that's when she saw her blue blanket with blood stains and her white stained panties. "Kyaaaaaa!"

Even the neighbors heard that scream, but not as loudly as the people who lived in that house.

How could she not see this coming? She had not been cautious enough to fall asleep with the special towels for this especially painful, shameful moment.

"Damn, I spent so much time thinking about dinner and waking up early today to make breakfast, I didn't remember to put them on, it feels so dirty in more than one way, if Iori sees it... Iori!"

It was with that name that her brain clicked and rose like lightning from the bed, her long blue hair waved a little, she removed her bed cover with violence, she made it a ball and threw it under the bed, just as she covered the bed with the sheets as quickly as possible, she already heard fast footsteps going up the stairs, just as her despair increased.

The girl took off her bloodstained white panties with speed, drowned out a scream from the sudden movements when her body was so delicate, but she didn't want to draw more attention with her little brother approaching, surely for her safety, after all he was a little angel of God.

"Geez, geez!" said the girl when she saw the bed, the floor, and somewhere else where she could leave her bloody panties, but she couldn't think of a place, so when she heard the door ajar, she hid them behind her. "Ah, Iori!"

"Are you all right, Onee-chan?" He asked as he looked everywhere. "Was it an insect or something? Are you all right?"

"Yes, I'm fine... I think..." She whispered with some difficulty because her belly was starting to hurt, she clenched her fists and forced a smile.

Iori was looking at her older sister with his pink eyes suspiciously, she was sweating from the forehead, with her hands behind her and in somewhat scandalous pajamas, as she was showing quite a bit of her thin legs; a bit provocative, really, after all, it was a boy.

"I don't remember her pajamas being that short". He scratched his short red hair, quite confused.

Of course not, her pajamas also had shorts, but she had taken them off to take off the panties she was jealously hiding behind her back.

Her crotch was enjoying the fresh, uncovered air.

"Why did you scream?"

"N-Nothing really... I just thought it was... Late, yes, that..." she said with some difficulty and began to laugh nervously. "But I'm just in time to make breakfast and I will once I take a bath, so if you can leave me alone to undress..."

"Yes, I understand, but you shouldn't scream for no reason, I think something bad had happened to you."

"Iori..."

He sounded worried, his gaze turned to her feet out of sheer shame; evading the area that aroused great interest in the female sex, even if they had no blood ties when she was adopted, she was his older sister, and he loved her.

When she noticed with her amber eyes the crystallines of her little brother, the pain of her belly moved to her chest, so she threw the panties without seeing, backwards, and approached him to surround him with her arms.

"Oh, Iori, don't get like that, I'm fine and I'll be fine." She caressed his head gently, feeling the warmth of her body, he blushed much more. "I'll make you a delicious breakfast that will make you forget about this too, don't worry."

She separated a little bit, took him by the shoulders and bent down to face each other, he was smiling a little and his eyes were better.

"We're in this together, nothing will happen to us, okay?" She shook his head and body gently.

"Yes, Onee-chan!" He definitely smiled, she smiled warmly and hugged him again.

As she separated, her little brother left the room and she was able to kneel on the floor when the door closed, she grabbed her stomach, her belly felt bloated, as if there was something stuck in there, and not only that, it seemed to be alive and with every intention of hurting her inside.

It was colics and a curse imposed on girls from adolescence to a little over sixty, and that if you were unlucky.

However, she couldn't be weak in front of her little brother, even if he wanted to show his manhood by protecting her, the truth is that he was very sensitive and smaller than her.

It would only worry him, he had not stopped being a crying child as when they were younger and for all the nice things that Iori did for her, it was impossible not to try to protect him and take the role of older sister in her maximum expression.

In addition, they were now alone because their parents had gone on a business trip, and when this was the case, Shiori took the reins of the home as if it were her mother, yet another reason for her not to cause any problems for Iori.

In fact, she had to solve whatever problems there were, and she had to take care of everything, even if no one asked her to.

Even with pain, she went to the bathroom with what she had stained with her blood to throw it into the washing machine, all this without being seen, also took what was necessary to bathe.

The pains continued, it was unpleasant that not even taking a bath could relax, she would have to change, make a good breakfast for both, then go to school, listen to the boring welcoming ceremony...

All those things sounded so problematic right now, even if she was completely fine, she could handle all that without problems and without complaints.

"I don't want to do anything". She immersed herself in the bathtub and after drowning out a scream, the water began to turn red. "Perfect".

Someone should be dead. It wasn't a prayer, it was an inner desire, she could almost feel her heart filled with hatred for her condition.

Good. Once she was ready and in the kitchen, in better mental conditions, things were fine.

She was grateful that Iori was nothing rebellious, despite being 14 and starting puberty, so he patiently waited for breakfast, already dressed in his dark school uniform, watching television in the living room.

"It's really so early that there's nothing interesting to see..." commented Iori as he passed the channels with a bored face, until he left it on a news channel, because he saw massive destruction. "Oh, it looks like a space earthquake happened near here".

"Ah, that again?" asked Shiori unimportantly.

This "natural" event seemed to be treated as if it were a rain.

But it really had no comparison, it was a large scale explosion that happened randomly and destroyed everything in the impact zone.

There was one of biblical proportions 30 years ago, it was the first of its kind and it was devastating, as well as several atomic bombs.

It happened in the center of the continent of Eurasia and more than 150 million people lost their lives in the blink of an eye.

Now it happened in a random way and it were not brutal like that, it also had measures and shelters for when one of these was detected, and contrary to earthquakes, it could be discovered before it happened, with an advantage of a few minutes.

So people could be saved, but not the infrastructure, but the technology, the government and other organizations had worried about this, so raising a house or a building again was not as complicated as it was years ago.

"It seems that they happen more often around here, that was strangely close, I hope one doesn't come by here or we'll be homeless and without anything..." said the blue-haired girl with pessimism suddenly, she hated her menstruation, but more hated the mood swings it caused her. "Hey, Iori, do you think we'll be all right? I don't remember if the house is insured or anything..."

"Maybe it's a little early..." he said quietly and took a palette out of his pocket, took off the wrapper and put it in his mouth. "Mmm".

"What did you say?"

"I don't know, Onee-chan, but I don't see it probable. Are you okay?" he spoke with a strange voice as he had the palette in his mouth, Shiori noticed, so she went to the couch, leaving breakfast in the middle.

"Iori, why are you eating candy?" she asked in a cold voice.

"Onee-chan, why are you like this? I always eat sweets before I eat, Okaa-san leaves me, you're too weird and when I went to your room, you didn't have your pajamas on completely, right?"

"Ah! That's..." she said embarrassed with red cheeks, remembering the terrible morning and the bloodbath just after. "That's... That's not..."

"Onee-chan, are you... In your days?" he asked with a mocking little smile.

"Give me that damn palette!" she shouted with a red face and eyes injected with fire as she chased him around the room. "You won't eat that until I'm gone! What the hell's going to happen to your teeth, sugar addict?!"

"You sound worse than Okaa-san!" he shouted as he hurriedly escaped from her. "And you wet the bed!"

"Shut your mouth, that's private!"

After chasing him for a while, Iori escaped from her arms as he skipped the couch, but Shiori hit her belly with the couch because she couldn't stop, she gave out a choked scream and was left on the floor.

"Onee-chan?!" he asked in alarm from the other side.

"I'm-I'm fine..."

"Sorry." He approached to help her get up. "It's been a while since you chased me like this... Does it hurt?"

"Yes, but not as much as before..."

"Today you shouldn't do anything then, how about we go to the nearby restaurant where they give that luxury dish?" he asked with a smile. "It's the opening ceremony, so we'll leave early, it's a good idea, isn't it? We have to go, Onee-chan! And that's also how you rest, it's like killing two birds with one stone, isn't it?"

"I think you're right, Iori."

"Really?" he asked, looking forward to it, didn't expect it to give way so easily. "I mean; I always have good ideas! So, are we going?"

"Yes, of course..." she said in some pain and stroked his head gently. "Just because it's a special day."

"That's great!" He raised his arms happily. "We have to go, no matter what happens, even if there are terrorists, fires or space earthquakes, nothing is going to stop us!"

"But you'd be scared to see a thief". She thought with a bitter smile, but nodded.

"Of course, Iori. But first let's have breakfast," she said as she got up and walked with his little brother to the dining room.

"Could I have dessert too? The ice cream looked delicious the last time, I'll even settle for a flan".

"We're not even there to tidy up, Iori" replied amusingly, while he raised his head a little to see her face with emotion.

"May I? May I?!"

"Oh, well, on one condition". She took his farthest shoulder with her hand to give her a half hug. "Support me while I'm on my period, your Onee-chan needs attention from a small, kind and strong boy like you".

"You just want me to give you a massage..." he replied a little annoyed, she smiled with disappointment.

"What's wrong with that?"

"Something special doesn't have to be conditioned".

"Of course I do, and I always have something special that kids don't have: colic!"

"It's not special if it happens to you every month, hmp!"

"Forget the special, it's a curse!" said something dramatic once they sat down to eat breakfast. "You have to help me ease the pain, and a good massage would do it, on my shoulders, ah and my back, if possible, also my arms, okay?"

"Just the shoulders..."

"Ah..." She bowed her head, he saw her so sad, he shook his head like a dog.

"All right! Just leave it to me..."

"I love you, little brother!"

It seems the day was brightening for Shiori and Iori Itsuka.
