"Appa, Is she my sister?" A baby face girl asked King Chungnyeol and pointed at the baby in the queens arms, It had been 7 months since you were born and right now, you're in your mother's arms sleeping

"Dae Taeyeon-ah" The king sighed tiredly

"Appa, Are you fine?" A boy with a sword stick asked

"Dae Soohyun, continue on practicing my son, because you and Taeyeon will go with Professor Ui later, you will study later with your sister since both of you begged for it" The king chuckled at how his son and daughter begged him

"Appa, me and Taeyeon will go now, we will study now" Soohyun and Taeyeon bowed at their father and went to the room where their teacher is waiting

The king stood up from his seat and went towards his wife

"How are you?" The King asked his wife

"I'm fine, and this little girl is fine too, She kepts on poking me when I though" The queen giggled and soon The King hugged you in his arms

"I wish they will be fine" Both of your parents sighed

17 years later

*poke*

"Mmrm" Taeyeon groaned

*poke*

"Ei..." Taeyeon muttered

Two girls smirked

"AHAHAHAHAHA!!!!!!!" Taeyeon let out her ahjjuma laugh as two girls tickled her

"Y-Yah! S-Soonkyu! Seungyeon-ah!!! S-Stop!!! I surrender!" Taeyeon let out a sigh of relief as the both of you retreated your hands

"Morning Unnie" You smiled at her

"Morning"

"Morning Taeyeon-ah" Soonkyu patted Taeyeon's head

"Morning" She let out a yawn

"Well, you girls better prepare yourselves then, your teacher has arrived already, and by the way oppa told me that The King will show you three to the people of Goryeo tomorrow" Soonkyu smiled at the both of you and walked out of the room

"So, Unnie, ready?" You asked her

"Go out first so I can get ready" You nodded 

"We will wait for you in the study room" You told her and you got a 'Dae!' for a response

As you made your way to the room and sat beside your brother. Soon Taeyeon joined in and The Professor thought you all lessons

"So, Who is the 12th ruler of the Goryeo dynasty?" The professor asked you

"King Sunjong" You answered 

"Correct"

"Taeyeon, What is the first Korean kingdom?" 

"Gojoseon"

"Soohyun, Who is th-" The professor was cut off by an arrow

The three of you stood up in shock when the professor ran out of the room and called for guards

Soon dozen of humans in black came in and showed up their swords

"Oppa" You mumbled 

Soohyun protected you and Taeyeon from the unknown figures

One guy in black stepped infront and soon had a sword fight with Soohyun, The guards came in and fought the other unknown guys

The ones in black are appearing and appearing as if there are millions of them suddenly someone grabbed you and Taeyeon from behind
"LET ME GO!" "YAH!!!!!!!!!!!!! OPPA!!!!!!!!!!!!!!! APPA!!!!!!!!!!!!!! APPA!!!!!!!!!!!!!!" 

You and Taeyeon shouted while getting carried away by the other unknown guys

You  and Taeyeon manage to hold Soohyuns hands

"OPPA!!!!!"

"SEUNGYEON-AH!!!!!!!!!!! TAEYEON-AH!!!!!!!!!!!" Soohyun cried

Suddenly, Your fingers are barely touching his, that means, you're getting carried away from him

You saw Sunny running towards you and Taeyeon but suddenly stopped when the guards stopped her

"OPPA!!!!!!!!!!SOONKYU UNNIE!!!!!!!" "OPPA! SOONKYU!!!!!!" You and Taeyeon cried and soon both of you girls were now outside the palace while getting carried away by the unknown figures

"SEUNGYEON-AH!!!!!!!!!!!!!!!" Soohyun cried, while kneeling, he was sobbing like crazy

"TAEYEON!!!!!!!" He shouted hoping he can get some response from his sisters

"Prince Soohyun" Sunny patted Soohyuns back

"Please, Please let me find them please!'' Soohyun begged Sunny and Minho

"I will order the troops now prince, and we will keep you safe too, and that will take more risk" Minho said 

Soohyun sobbed and sighed

"T-Then *sniff* F-Find them as soon as you can, Jebal... I.. I need my sisters to return safe and sound, Please promise me that" Soohyun cried

"I promise, Now go inside and rest, You need to rest now" Soohyun obeyed Minho and tiredly walked inside the palace again

Minho left to order his troop to prepare theirselves 

Soonkyu followed Minho

"I'll follow you, I'll find them too, Please let me oppa'' Soonkyu begged her brother

"Soonkyu, Stop being stubborn, Oppa was ordered by the king to find his daughters, and so oppa needs to order his troops to find the princesses, Please, Stop being stubborn, oppa can't afford to lose you too" Minho hugged his younger sibling

"Oppa, L-Let me find them please, I need them, I want them to be with me, I need to find them" Soonkyu begged once more

Minho sighed

"I can't do anything about that, Go and wear one of my suit, You will come with me and my troops, you still remember how to use the sword and ride a horse, Right?'' Minho asked his sister

"Dae" Soonkyu nodded

"Okay, Get ready, We are going to search for them after preparing" Minho left Soonkyu and Soonkyu rushed towards his brother's room to get the suit and the armor

'I'll find the both of you, I promised that'   Soonkyu promised

Sobbings were heard inside an In in a place in Yuan

"Shut Up!" A guard shouted and slapped one of the princess

"YAH! DON'T YOU DARE HURT HER!" Taeyeon shouted when she saw you getting slapped

"Oh! Sorry Princess! BUT YOU'RE NO LONGER IN GORYEO!" The guard sarcastically shouted back and laugh with his friends

"Are you fine Seungyeon-ah?" Taeyeon asked you

"I-I'm fine unnie, I- I just want to go home soon" You cried

"Shh... I-I'm here" Soon you fell asleep in Taeyeon's shoulder

"Oppa.. Where are you?" Taeyeon sighed tiredly while looking at the only window in the room

"Please..... Come here and save us, Jebal..." Taeyeon said before going to sleep
