Warning spoilers alert!
I get this story from one of the chapters from the manga of Akatsuki no Yona.

***

Flashback, when Yona is 6, Yoko is 8, and Hak and Soo-won are 9.

Yoko's pov:

I sigh in boredom while i followed King Il around the palace.

The King opens the screen door revealing three children in it.

"Hak, Soo-won, Yona i like you all to introduce Yoko." he gestures me behind him. "She will become one of your main servants Yona."

"Nice to meet you all." i bowed lowly to them.

All look curiously at my appearance. I was wearing a huge black cloak, a white kimono that is up on my ankles, a dark purple vest with a v neck, and sandals.

I have not look at the princess, yet. However as i feast my eyes on her, my blood boiled and my wings started to throb in pain. Then a voice came in my mind and said:

"You are now our other halves. You will serve Hiryuu as your master, protecting him with your lives. You will love him, and never betray him."

"Hiryuu? I do not know anything about the legend of Kouka. I knew nothing about it especially Yona is my master and i am just her servant. However, words like these would never say that to me before. Moreover, who is this voice that speaks to me?"

I stayed up and managed not to flinch. The young princess' hair color is red like the color of the blushing dawn.

The King smiled then left because he had a meeting with the other five Generals, leaving Yona, Hak, Soo-won, and in the room.

I sighed. How could i get along with those people?

Time skip>>>

They all get uset to my weirdness. I ignored every single pain in my body especially my wings on my back that i covered it with my cloak. I shuddered while carrying a tray of pot full of tea and cups. Soo-won notices my actions.

"Yoko, are you okay?" the blond boy asked me in concern.

I nodded. "I'm fine... It's just i'm nervous." i smiled weakly at him.

Soo-won touches my forehead.

"Yoko, i think you had a fever." he said then releases his touch.

I flushed in embarassment. "No my lord, it's just i drank too much tea earlier and i walk distance to get here in Kouka kingdom." i pouted.

Soo-won look at me in sweat dropped.

[night time]

Third person's pov:

Yoko was still standing while watching the three children.

"It's always lively outside the castle." said Yona over-looking the balcony. "It's brighter than the stars in the sky. I wonder what's happening."

"Yona, you've never been to the town of the castle?" asked Soo-won.

"The princess has no sense of direction, so she'd get lost." Hak teased while eating a bunch of grapes.

The princess started to throw objects at him. "WHO HAS NO SENSE OF DIRECTION?!" she shouted.

"I'm glad you two such good friends." Soo-won smiled.

"HOW CAN SEE IT LIKE THAT, SOO-WON?!" Yona snapped at her cousin.

After the red haired princess calmed down, she look down.

"I've only seen the castle's town fron here. Father says i can't go because it's dangerous." she explained.

"Really?" Yoko asked her master in disbelief.

"Yes." she replied.

"......"

"Do you want to go?" Soo-won broke the silence.

"Huh?" Yona turned to him.

"Do you want to go see the castle's town?" the blond boy asked the princess.

"I... I can't! Father has forbidden me from doing that. Because it's dangerous outside!" Yona blushed and averted her gaze away from him. "First of all, i don't really... Want to go outside..." she turn back to them.

The princess stare at the three with a serious angry look. Hak munch an apple while Yoko was still standing.

"Shall we go?" Soo-won broke the silence.

Suprisingly, she nodded.

The next day...

Yoko's pov:

We sneaked out the secret passage that Soo-won found. To be honest, how did he found it?

They have been forcing me to go out with me. Me on the other hand, had forcing them not to.

Outside the palace and we're here in the town. Hak, Soo-won, and i are out while Yona is still hiding. We tried to convince her, but she is really shy. Luckily, Hak teased her that she tried to hit him.

As Yona is out, she began to glow and sparkled at the busy streets and crowded people.

°o° "There's so many people...!" Yona sparkled in amaze.

"Are you sure about this Soo-won, what happen if we get caught?" i asked, clenching my shoulder bag filled with useful stuffs.

"Don't worry. There's a five tribe meeting going on right now." Soo-won said positively. "Let's play around until the meeting ends."

"But you know some bizarre secret pathways, huh?" Hak turn to the blond boy.

"It's a daily adventure!" Soo-won replied.

"Do you three come here often?" Hime-chan asked us while i was holding her hand.

"My grandpa brings me once in a while." Hak answered with a monotone voice.

0.0 "That sounds great. I want to come with General Mundok, too." said Soo-won.

"He kind of reminds me of my late Grandpa." i smiled.

"It's just noisy." Hak groaned.

I don't think Hak and his Grandfather didn't get along well. Because he felt uncomfortable.

"How about Soo-won?" Yona-hime turns to her cousin.

"I've come just a few times." he replied simply.

"Yoko?" turns to me.

I shrugs. "It's my second time here. When i first got here, i immediately started to work in the palace as your servant, Hime-chan."

All stare at me.

"Now then, let's go, let's go!" Soo-won changed the subject.

Yona let go of my grip, and tried to look, but the crowds are blocking the view.

Hak smiled. "Heh Princess."

He lifts Yona and places her on his shoulders. We look at him in awe. He's so strong.

"Can you see?" he asked the princess.

"Y-yes." Yona bluntly answered.

Me and Soo-won are lagged behind the crowd while trying to keep up with them.

"Soo-won, Yoko." he outstretch his hand to us.

Soo-won grab Hak's hand and i grab Soo-won's hand.

"E heh heh heh!" Soo-won laugh sheepishly.

"What?" Hak asked.

"It's creepy." i replied. "If i had a big brother... It would feel something like this, don't you think?"

"Oh-?"

"Oh..." Hak muttered. "In Fuuga, there are a lot of smaller kids. You guys are easy compared to them." he explained.

"Hey Hak, what's that?" Yona pointed at the small looking fried balls in the pan. "It's the first time i've seen food like this."

"Welcome! These are deep-fried dumplings, and they're good!" the old man greeted.

"Do you want to try it?" Soo-won asked Hime-chan.

"...I can't eat this stuff." Yona-hime stated cautiously. "The poison taster isn't here, either. I'll be scolded by father."

I know the royal family has a poison taster to taste the food in case it is poison.

"Then i'll taste it for poison." Hak volunteered.

"Huh?!" me and Soo-won sweat dropped from his words. What happen if he get killed from poisoned?

"Hak, you're so cool <3" Yona chirped.

Hak started to pick a piece of dumpling amd eat it. Soo-won gasped as he saw something and pushed us at the side of the stall to hide.

"What's wrong?" me and Yona asked in confused while Yona sat on poor Hak.

"It's Joo-doh." said Soo-won looking at the black haired man with a scar below his eye wearing an armor.

"Who's Joo-doh?" i asked with question marks surrounded me.

"The Captain of the Imperial Gaurd's first squad, Han Joo-doh." Soo-won explained. "It seems he came to find us."

"Joo-doh's a quick-tempered person, isn't he?" i commented.

"Hak!" Soo-won gasped.

"Hak!!" me and Hime-chan screamed at poor exhausted Hak.

"Is this... POISON?!" Soo-won screamed.

°o° "IS IT POISON?!" Yona deadpanned.

"This is terrible he has to throw it up!" i stated in panic.

"Yona! Hold him up so i can hit him in the stomach!" Soo-won ordered.

Yona obeyed, then sat Hak up, grasping at the neck. "Got it!" she replied.

"Soo-won! The pit of his stomach is here!!" i pointed out.

"STO-P!" Hak stood up in fury. "... Understood. You guys are more trouble than the kids back home."

We gave him a teary look in relief that it wasn't poison. The old man gave Hak a cup of water and he drank it.

"-So?" the shop owner gave us a menacing look. "You're making a complete ruckus in front of my store with talks of poison and whatnot. Do you brats have any money?"

Hak, Soo-won, and i sweat dropped after he said the word 'money'.

"Money... Yoko, do you have any?" Hak asked me.

"Huh?" i sweat dropped. "I always have some, but..."

"In other words, you're saying you don't have any now?" the old man gave us an angry look.

Hime-chan stood up. "Understood! Come to the castle later!"

We are completely shock when she said it and we covered her mouth, grinning at the old man sheepishly.

"Mff Mff" Yona muffled.

"What did you say about the castle?" the old man asked suspiciously.

Soo-won turn his head then gasp. "Please wait a moment." he replied then left.

He went towards to an old man, then asked him to borrow some money, and he gave Soo-won a small bag. He return happily.

"Here's 65 rin. Please give us twelve more dumplings!" Soo-won handed the shop owner the money.

Me and Hak glare at him.

"Hey!" he innocently look at us.

"What's the deal with that, money?" i asked him.

"What's the deal with that old man from before?" Hak asked suspiciously.

"A kind old man gave it to me." Soo-won replied with an closed eye smile.

òOó "That's not true." my jaws dropped in disbelief.

"Why did that, old man give you money?!" Hak yelled.

After the man gave us four sticks with three dumplings each on it. We started to eat.

"It's delicious." Soo-won commented.

"He put plum bean jam inside these, right?" i asked.

"Yeah. The jam is good." Hak grinned. "Wait, forget that. What about the old man from befo..." Soo-won cut him off.

"Yona, is it good?" he turn to the princess.

Yona didn't answer and her cheeks are chubby and cute! >v<

"You're so cute, Yona." Soo-won smiled.

"You look like a squirrel." i commented.

Hak places his hand on Yona's hair. "You're cramming your cheek pouch too much." he acts like a big brother. "Old man, give us some tea."

"Aren't you guys unrestained!" the shop owner sweat dropped.

So, we left the shop and continue to walk around the streets, quietly with no hesitation. I hold Yona's hand.

"The music of that musician earlier was pretty. I want to let father listen to it, too!" Yona broke out a convernsation.

"I want to listen to my father, too." Soo-won commented.

"Don't worry. When we get back, i will play it for them!" i replied. I know how to play the instruments for my life.

While Hak on the other hand had a different mind. Then Yona and i suddenly bumped to someone.

"Hey, you." the stranger yelled at us.

We look up and saw a familiar looking person turn at us.

"Don't you have something to say about bumping into me? Hm? Kids?" he gave us an i'm-waiting look.

"I've seen your faces somewhere." said Yona-hime.

Then Hak blocked us. "Sorry. They're my little sisters. Please pardon them." he apologised to the man.

"I WILL NOT!" he stammers. "Because i am...the second son of the Fire Tribe's general, Kan Tae-jun!"

Now i remember and his greetings are just his main line.

But we didn't listen to his usual speech. Yona showed us a cat and its so cute!

"Listen to me, you brats!" he grab Hak's shirt and yelled at him. "If i tell my father about you, you'll get 100 lashings!!"

Hak rolled his eyes not listening to Kan Tae-jun's nuisance words. "Sorry. There, i said it." Hak annoyingly apologised.

"It's, 'Lord Tae-jun, i apologize. Please have it in your heart that's deeper than the sea to forgive us'! Kneel on the ground!!" Tae-jun yelled.

"I'm zorry."

"You're pissing me off, kid!"

"Master Tae-jun, calm down. I'll give you a dumpling." Soo-won stated calmly.

"I don't want it!" i could see veins popping out on his head.

I let go of Yona's hand. "How about a nice cup of tea?" i commented.

"No!" he snapped.

Then i realized that Yona isn't here anymore. "Hak, Soo-won! Yona isn't here."

"What?!" Hak turn to me. "Damn...!"

We run away from Mister Kan Tae-jun and started to search for Yona-hime.

This is my fault!
