Once upon a time, on a quiet day at Hattori's residence, during a summer holiday ...

"Hiro, how many times I should tell you? Please concentrate! Do not daydream! See? Your writing is over the line!".

And the quietness was suddenly snatched away by the voice of Kazuha Hattori who had just reprimanded her son, while now removing unruly pencil scribbles in his notebook with a rubber eraser.

The son, Hiro Hattori, is now glancing at the little girl beside him, his twin sister.

"Mom! Kana's writing also crossed the line! And ugly! Why only me being scolded? Why, why, why? Why, Mom, why?" Now he made a mock rhythm, before then he added. "I want an explanation, Mom!". Maybe if the situation was different, Kazuha would laugh. He's definitely Heiji's son, they have similar style of speech!

The twin sister is now looking at her brother with annoyance. "You're so noisy! Just do yours, no need to comment on mine!".

Hiro was taken aback with an exaggerated tone. "See? You see? She just yelled at me, Mom! Bad girl! Baaad girl you are Kana!".

Kazuha sighed as she massaged her temple. Here we go again ...

"Shut up!".

"You shut up!".

"No! You shut up!".

"No! You shut up!".

Okay, that's enough! Obviously that words are inappropriate for spoken by four-years-old!

They must imitate those inappropriate words from the criminal movies they often watch with their father. It seems that both of them are also endowed with their father's intelligence. Otherwise it would be impossible for two four-year-olds to be able to enjoy detective movies and other movies of such kind. Still, they're way too early to get to know such a movie. And those languages!

"All right, all right! Enough you two!".

Alas, Kazuha ignored by them.

"Kids! Kids? KIDS!" Kazuha finally shouted, to make her voice heard between her children, and instantly felt dizziness and nausea struck her. Strange. Since three days ago, she suddenly had a frequent dizziness and sudden nausea. Perhaps the symptoms of colds?

"Ukh ... Umph!" Kazuha covered her mouth, struggling not to vomit in front of her twins.

"Mom!".

"Mommy!".

Both Hiro and Kana soon forgot their quarrel when they saw their mother sick. The two kids ran up to Kazuha at the same time. Kazuha waved her hand, still slightly nauseated, but had managed to cope so she did not throw up.

"Don't worry, I'm fine!" She gently stroked the heads of each of her children. "You two finish your writing exercise, I'll be back in a minute!". Kazuha then stood and walked away from her twins who looked at each other now.

Kazuha walked slowly with a sigh, a mixture of annoyance and exhaustion. Where is Heiji when she needs him? Right at the moment like this, he usually disappears without a trace like smoke. After this, better if she gives a long talk to her husband about sharing duties as parents. That and about the rules of watching criminal movies that clearly not good for the vocabulary development for toddlers like Hiro and Kana.

"Umph!". Soon, the idea of talking to her husband was all forgotten as once again nausea hit her. What's wrong with her? Maybe she should immediately go to the hospital. But for now, she has to go to the loo first!

"It's all your fault, Hiro! Now Mommy's sick ..." Kana's lips began to tremble "What if ... What if the sickness is serious? Then ... Then Mommy will die uuu ... uuu ... uwaaaa ... I don't want her to die!" Kana was crying out loud now.

"No, she won't! Ssh! Stop crying, Kana!" argued Hiro defensively.

"But ... But ..." Kana answered in a sobbing voice.

"Mommy will be fine! Didn't she say she's all right? You heard it yourself, didn't you?".

Kana didn't answer, she was still sobbing. But both of her eyes said she doubted Hiro's answer.

Actually, Hiro himself also hesitated. Their mother did look sick. Her face was very pale and there was a lot of perspiration on her forehead. Hiro had accidentally touched his mother's arm. It was cold. He swallowed in horror. In the movie that he often watches, usually it is a sign of the victim and will soon be ...

Hiro shook his head firmly, casting out the bad thoughts while standing up and invites his sister.

"C'mon Kana, let's find Daddy!".

"Hiro, will we not be scolded like before? You know, when we make a messy in dad's room?" Kana whispered fearfully as they walked toward their father's study room, because they were once scolded when making Heiji's room as their playroom. The room that was originally neat it suddenly became chaotic as hell, as if there has been a riot.

"Ei, you stupid! We're just gonna tell Daddy about Mommy instead of messing up his room again! Of course we won't be scolded!".

Kana scowled. "Who are you calling stupid, stupid?".

Hiro rolled his eyes "Is there anyone else here besides you? Now be quiet! We're here!". Hiro knocks on the door of his father's study. He deliberately did not allow Kana to argue with him.

Knock ... Knock ... Knock ...

"Dad? Daddy? Can we go in?".

He waited for a few minutes. Because there's no answer from his father, Hiro knocked again, before he finally opened the door.

And it turns out, the room was empty.

Hiro frowned. Strange. Here is usually where his father is when he was at home and not playing or watching television with them. But now, nobody inside. Hiro was about to ask where their father is to his twin, when he hears his voice, comes from the living room.

"Come on, Kana!" he said, pulling his twin.

"Don't pull me! I can walk myself, you know?!" Kana protested, but Hiro ignored her.

As they drew closer to the living room, there was another voice. A woman's voice, spoke in a low, husky voice.

'Oh, apparently Dad is having a guest' Hiro thought.

The door to the living room was ajar and Hiro hesitated. He knew it wasn't polite to interfere when his father was having a guest. But, isn't this an emergency situation?

Biting his lips with a little fear, he ventured to peek into the living room and instantly his eyes widened in shocked.

His daddy ... The father he was so proud of, was now embracing the stranger woman ...

Time seems to freeze for him.

Hiro seemed to wake up as he heard a startled voice at his side. Luckily her sister's voice was not loud, exactly like a choked voice. Quickly, Hiro smothered his sister and pulled her away from the door, before their father who had a super sharp hearing caught them.

When they finally reached the kitchen, the two poor toddlers curled up trembling.

What have they just seen?

Their father embraced with an unknown lady?

For real?

He's not wrong look isn't it?

Hiro glanced at Kana. By her reaction, he did not look wrong.

But ... If that's true ... That means ... That means ...

Okay, Hiro doesn't quite understand the meaning of cheating, yet.

However, his hunches say, what he and his sister have just seen, are things that should not be done and dangerous.

Very dangerous.

"What are you two doing here?" Hiro looked up in surprise when he suddenly heard a voice he knew very well, his mother's.

'Uh-oh' Hiro thought. 'Another danger!'

"Hhh ... I told you to finish your writing exercise, but you guys are playing hide-and-seek here?" Kazuha sighed and bowed, trying to grab her two children, when she realizes that they are trembling. In addition, even Kana's eyes were wet.

"What's wrong? Why are you trembling?".

Hiro is the one who replied "It's okay, Mom. We're fine".

But of course Kazuha doesn't believe him. I mean, how good a four-year-old kid lies?

"Do you guys get scolded by your Daddy?".

Hiro and Kana's heart froze when Kazuha mentioned their father and finally made Kana can not stand it anymore and sobbed as she hugged her mother. "Uwaaaa ... I hate Daddy!".

Of course Kazuha was shocked. Hiro was also shocked, but not as surprised as his mother.

"Ka-Kana? What is it, Honey? Why you suddenly ...?". Instead of answering, Kana cried harder, though silently, and embraced her mother more tightly.

Kazuha is now looking at her son with a questioning look. "Hiro? What's going on?". Hiro could only stare at her mother with the innocent eyes of a child who could not lie anymore.

"Hiro?" Kazuha urged him again.

"We saw, Daddy was with a woman in the living room" Hiro finally said in a low, quivering voice and Kazuha's heart is squeezed by an invisible hand. Her whole blood was frozen in her veins. Somehow, she felt she wouldn't like the continuation of her son's sentence.

"They were ... They were ..." Hiro started to sob.

"They're what, Hiro?" Kazuha could only whisper in a low voice.

Hiro swallowed hard. "They-They're hugging each other, like when Dad hug you, Mom! They ... uuu ... uweeee ..." Hiro is now also crying in his mother's lap.

The world seemed to collapse for Kazuha.

Impossible!

This is impossible!

'Okay, okay, calm down! You have to calm down, Kazuha! Your kids still toddlers, they must be mistaken and misinterpreted! There's no way Heiji cheated on you as they say! I mean, you've known him since you're a toddler!' Kazuha commands herself inwardly.

"Hey, hey, it's okay! You must be mistaken! Daddy just with one of his friends, that's all! Nothing happens!" Kazuha tried to convince her two children, though she herself wasn't one hundred percent sure.

When Hiro and Kana just looked at her with hopeful eyes, as if to say "Really?", Kazuha spoke in a more convincing voice "Yes, that's right! You say Daddy is in the living room, isn't he? Let's meet him and his lady friend ..."

"No, Mom! Don't go there!" The twins prevent their mother at the same time.

"It's okay. Come on!" Again Kazuha tried to speak, or rather, squeak, in a calming and reassuring tone, although when she heard her own trembling voice, she knew it was a failure.

Frankly, Kazuha is also afraid to prove, but she's also curious.

'Please don't! Please don't! Please don't!' Kazuha prayed silently.

As they reached the door, they heard Heiji's distinctive voice, with his thick Kansai dialect, talking to the woman who was also in the room, though it falters.

"Don't worry ... must be loving you!".

Three pairs of eyes wide open when hearing the voice they believe is Heiji Hattori's voice. Alas, their surprise was not over yet, because the next voice they heard was the sound of a happy sigh from a woman.

Blinded by curiosity and jealousy, Kazuha bursts in, only to see her husband, the only love in her life, again hugging a stranger woman, just as the twins told her.

Is Heiji ... having an affair?

No!

No, no, no!

No!

This is not happening!

But ... But what she saw with her own eyes ...

"No way ... Hei-ji?".

"Ka-Kazuha?".

Heiji is aware now that Kazuha is staring at him with tears in her eyes, a pale face of disbelief and her whole body trembling, spontaneously sure what is currently in his wife's mind.

He had not even released the woman in his arms yet, when Kazuha, without another word, was already running away, leaving him.

"Wait! I can explain!" He said in vain.

"Mom!".

"Mommy!".

Kana immediately ran after her mother.

As for Hiro, he turning to his father for a moment and yelled loudly "I hate you, Dad!" then he also ran after his mother and sister.

Heiji can only freeze on the spot.

Why ... What ... How can it end like this?
