15 Years Ago.

15 years ago,

Naeun had some problems with her heart from her birth. But when she turned 4 it became critical. She had lost her mother when she was a few months old and only her father was left to give her the love she needed. An operation was necessary for Naeun and her father, Park Byunsoo decided to go with it. Naeun was in the hospital ward with her father right beside her.

"Daddy, am I going to die?"

"No my princess, you aren't." Her dad replied and kissed her forehead. "Everything will be fine and I will be right beside you when you wake up. Be strong okay? No matter what happens, promise me you'll be strong?"

"I will."

The operation was successful but when Naeun opened her eyes her father wasn't beside her. A week passed and there was no sign of her father. After 2 weeks Naeun was lying on the hospital bed and when she heard the door open she turned towards it hoping it could be her father; but instead 4 men dressed in black entered.

"Who are you? Where's my daddy?"

"We are your daddy's friends. We are here to take you to him."

Naeun, who was as clueless and innocent as any 4-year-old could be went and followed the man overjoyed that she was going to meet her father. The men left her in a room with a bed at the farthest corner covered with a white sheet. She was about to head towards it but the door opened and a man in his late 50s along with women in her late 20s entered the room.

"Where's my father?" Naeun asked softly, staring at the strict-looking man.

"I don't think we should do this sir." The woman whispered but the man shot her a glare instead.

"Be quiet Agent 067. I know what I'm doing." He then turned to face the little girl.

"Your father is lying down on that bed. Remove the sheet and you'll get to see him."

Naeun smiled excitedly and ran towards the bed. Flinging off the sheet she screamed in horror and fell on the ground hiding her face in her palms. The face she had seen could not be described. It was distorted, unable to be recognized. And a very traumatizing scene for a 4-year-old girl.

"You father has died. Actually he was murdered. Do you know who killed him? It was you. You stabbed him in his sleep and took out his heart."

"N-No...n-no..." Naeun stuttered shaking her head furiously.

Naeun needed a heart transplant for her to survive. The heart should have the same genes as her and her dad was the only one who had them. In other words, he gave his life for her. It didn't mean that she killed him. But the man's job was to brainwash her.

"I think it's enough!" The woman shouted over Naeun's cries and screams but the man took no notice.

"I-I didn't kill my d-daddy! I-I couldn't!"

"You did. That's how you're alive and he's dead. That's how this world works. We can survive only by taking others lives. That's how you're world will work."

"Oh and that's not all." The man continued on. "Don't you ever wonder where your mom is? She died when you were born. You killed her. That's why your father always used to cry on your birthdays. Your mom and dad were our best agents. Now they are gone. All because of you. Now you can be a good girl and listen to what we tell you to do. You will train to become an agent in place of your parents. That way they will be happy and proud of you. Now be a nice little girl and train hard!"

He got up and kicked the chair hard making Naeun flinch and shake. He had washed her brain thoroughly. After he had gone the women, who was actually Mrs. Han knelt before Naeun.

"Naeun listen to me. I am going to take you to my house but you have to be quiet and disciplined in front of my husband. You will go and train in the Agents academy to become an Agent. That's what your dad wanted."

"W-When will t-this end?"

"I'm sorry. But this will never end."

2 years later,

Naeun now being 6 years old had been living with the Han family. Continuously being scolded and abused by Mr. Han automatically made her attached to Harin. Mrs. Han was taking her somewhere today but she hadn't told her where. She left Naeun in a dark room alone with nobody. After some time the man who had brainwashed her 2 years ago entered and behind him 2 men came dragging an injured man.

"Hello Naeun, how have you been?" asked the man whose actual name was Mr. Jung.

"I am f-fine," she replied staring at the bloodied man that was dragged in.

"I have a job for you and it is very fun to do. It's like playing a game. Do you want to play? You have to shoot this guy there and then I will give you a present."

He handed Naeun a gun while she started crying saying "no".

"Kill him now!"

"I-I don't want t-to!"

"Press your finger on the trigger and SHOOT HIM NOW!!!"

Naeun flinched by the sudden shout and accidentally pressed the trigger. The bullet landed straight in the man's chest.

"Impressive! You have a nice aim. Good job!"

But the girl took no notice of the compliments and continued on sobbing staring at the man who was taking his last breaths because of her. But the last words the man uttered from his mouth Naeun never forgot in her life.

"It's okay kid. This is just the beginning."

4 years later,

Naeun jumped off her bunk and stared angrily at the loud noises her roommates were making. Now being 10 she had been enrolled in KIA training academy but the girl wasn't the same as he used to be.

"Yah! Shut your mouths I can't sleep over your damn noises!"

"Keep quiet Project-A20!" the boy shouted. Trainees were used to be called Projects in the academy but the boy wasn't aware that he was bringing his death.

"It's okay Naeun. Don't worry." the girl said who was no other than Suzy being bullied.

"What can she do!? You both are never going to qualify as Agents!"

"Yeah! I heard that she's a monster. She stabbed her father and that's why she's here. We all are here because our parents were agents but she's here because she murdered an agent."

Naeun didn't cry or sob. Instead, she chuckled darkly and stared at the boy creepily. She started walking close to him while he gulped.

"Y-Yah! Project 20 what are you d-doing?"

"You know if I can kill my father you should be a piece of a cake."

"Oh yeah? Come and try us! We aren't weak!"

10 minutes later the head trainers came running in when they heard noises. Naeun was standing in the center of the room without a single scratch and all the other boys and girls were knocked out with cuts and bruises.

"Project-A20 no food and no sleep for 1 week! You will come with us to get your punishment."

Naeun went silently with a blank face behind the trainer while the other trainers stared at the scene with shocked faces.

"We are creating monsters."
