When Y/N was born, Jungkook was not so happy about it.
Jungkook being the stubborn 9 year old kid felt jealous. He thought that you will steal all the attention.
--
Months later, you started to learn how to crawl, and Jungkook will sit on your back, hoping you will die so he will get all the attention and love again.
He wants to throw a bunch of blocks on you so that you'll get wounded, then you will be sent to the hospital, then later on, die. He's trying all the ways, to hurt you, so that the old attention and love will be back.
As you grow up, he started telling you fake stories like you were just adopted and his parents doesn't really love you.
He also told you that his parents found you in a garbage can and took you because you look pitiful.
--
You're holding Jungkook's hand as the both of you walk through the big mall.
Jungkook rolled his eyes as he felt your tiny hand tighten around his.
You're walking around, parents infront. Suddenly, a cute pink bunny stuff toy, attracted your attention
You ran for it as you touched it in awe.
"Hey Little Girl, do you want to buy this?" The shop owner asked as she kneel down in your height
Her hair's tied on a messy side braid,
She has a black glasses on that fell on the bridge of her nose. The glasses is not too big to cover her brown beautiful eyes.
You shook your head, "My brother's h--"
You looked behind your shoulder as you can't see Jungkook around.
You looked around trying to find either your parents or Jungkook.
You looked at the shop owner, tears surrounding your eyes.
"A-Are you lost?" She asked, a little flustered
"I d-don't know, where t-they are" You cried as the tears flowed
The girl carried you inside her shop,
"Stop crying, I'll help you find them, okay?" She calmed you down as she wiped your tears using her thumb
You nodded as you placed your head on her shoulder
"What does your brother look like?" She asked as the both of you walk to the place where children who lost their parents are
"His height is like this," You said as you placed your hand on the air, estimating his height
"He has black hair, he styled it this morning, it's combed to this way" You said as you explained his hair
Meanwhile, Jungkook is smiling like an idiot. He finally succeed with his plan without thinking the consequences that he might face.
"Kook? Where's your sister?" His Mom asked as he looked at his empty hand
"I don't know. But isn't it much better? Just us? Without her?" He smiled
"What are you saying Kook? How can you say that your younger sister?" His Mom asked in disbelief
Jungkook was left in shock, he thought that his parents love him only. Only him.
"B-But.. I thought you l-love me?" He asked
"We love you Kook, we also love Y/N. And you acting that Y/N is not your sister, is bad Jungkook" His Dad scolded him while trying to look for his lost daughter
He can't believe that his loving son, has this kind of thoughts.
"We're here, Y/N. Play here, while we try to find your parents okay?" The girl said as she put you down on where the dolls are
You looked around as you saw blocks and you immediately played with them
Growing up with a brother, you got influenced by his likes and dislikes.
"Attention to all shoppers, if you lost a child named Jeon Y/N. She's in the lost child center, at room 2. Thank You." The voice of the manager of the center roared through the area
"Let's go Jungkook. Your sister is there." His Mom said as she took his hand
"Y/N!" His Mom said as she hugged you
"Mom!" You said as you hugged her back
"Let's go, Jungkook needs to tell you something, Y/N" Their Dad said as he took his son's hand
--
Their Dad took them to the bathroom as he placed their back on the blue wall
"Jungkook. Mom told you to hold Y/N's hand, and what did you do?" Their Dad sternly asked. Disciplining his own son as he doesn't want this to happen again
"I let go of her hand," Jungkook said, guilt in his voice
"And why did you do that?" He asked again
"Because.. I thought you don't love me anymore. Your attention is all on Y/N now." He said as he looked away
"We're not gonna do that Jungkook. We both love you, equally, no excess love and attention and no lack of love and attention. Do you understand, Jungkook? Y/N?" He asked his two children
Their Dad opened his arms as the two children went to his arms.
"I'm sorry, Y/N. I won't do it again" Jungkook said as he kicked his feet back and forth while sitting on his bed, wearing his pyjamas
"It's fine." You smiled as you hugged the pink bunny that the shop owner gave to you
The both of you hugged as the bond is starting to grow.
--
After the incident, Jungkook finally accepted you and the fact that both of you will stick to each other until you grew up.
While you, still accepted Jungkook even though he sometimes teases you,
Do you have a brother?
I have a brother, and I grew up with robots, cars, and blocks.
I didn't played with dolls, because for me it's creepy.
