"____-ah, be a good girl in your new family alright?" The head of Seoul Orphanage said as she patted your head.
She was the one who took you in and watched you grow up.
Tears were forming in your eyes as you nodded and forced a smile. 
Finally, after waiting for so many years, you finally got yourself a family.
You looked at your new parents, Mr and Mrs. Kim.
They genuinely smiled as they led you to their shiny black car outside the orphanage. 

"Thank you, Mr and Mrs. Kim." You said thankfully, bowing a few times to express your gratitude. 
"Call us Mom and Dad, ____-ah." 
You broke into a smile. "Thank you, Mom, Dad." 
Soon, you and your new parents were driving on the road. All of you were laughing hysterically over a joke that Dad told. 
"Oh! Right! ____-ah! We forgot to tell you. You will also have a brother! His name is Kai. You will be attending the same school as him too!" Mom said. She sounds very excited, apparently. 
Kai..? You thought. "But you won't be sharing the same room, of course!" Mom continued. 

Dad nodded in agreement, at the same time trying to focus on the road. "Don't worry, ____-ah. Kai may seem cold at times but he can be sweet too." 
Your mind wandered off, you started to worry if you cannot get along with your new brother. 
Mom and Dad continued talking about Kai, but all you could feel was worry.
