Jungkook's age in this chapter

Jungkook flutter opens his eyes, as the sunbeams that running here and there in his room disturbed his peaceful sleep. He can feel a little weight on his chest and a smile breaks through his mouth, glancing at his four years old half sister. Although it's only been around a year with her addition to his life, and he got a mother, his love at this point, is overwhelming for the new family members. He runs his fingers through y/n's soft hair, who's still sleeping peacefully on the top of him. The parents were again busy with a business tour, which made him take care of the girl.

"Baby, wakie..."

Jungkook softly pats her back, making the girl stir from her sleep. She opens her eyes once but the light was too much, so she closes her eyes again.

"No...Koo's huggie is nice"

She mumbles, falling back to the sleep. Jungkook chuckles, deciding to let her sleep for few more minutes. He slowly lays her down on the bed again, pulling her into a gentle hug as he closes his eyes, thinking how can this girl miraculously get him agree to do anything she wants.

"Good that it isn't a university day"

He mumbles, letting go a sigh, which interrupted the girl. She opens her eyes and blinks several times, before focusing them on Jungkook.

"Oops, I'm sorry, princess...I didn't meant to wake you up"

Jungkook says, being honest for his words.

"It's okay, Koo.."

She mumbles, snuggling into him more. He chuckles, kissing her head several times. Knowing they can never leave the bed if they keep cuddling like this, Jungkook gets down from the bed, carrying the girl in his hands. He steps inside the washroom, placing the girl on the counter. Next he put some baby toothpaste on her toothbrush and gives it to her, earning protests from her.

"Babies should brush their teeth or else monsters are going to eat them"

Jungkook says with horror, making the girl gasp of the thought of going away from her oppa. She immediately snatches the toothbrush from Jungkook's hands, making him chuckle.

"You are too adorable that I doubt whether my heart can deal with it"

He says, kissing her forehead as he starts brushing too. After playing around, he was finally carrying her to the kitchen to prepare something to eat.

"What do you want to eat, baby?"

"Anything Koo likes"

"But, baby..."

"No, Koo...you everyday eat things that I like, so let's eat something Koo likes today"

He let goes a soft chuckle, staring at her tilted face, doe eyes and happy smile in adoration.

"What happened, Koo?"

He let goes a sigh, as he shakes his head before pulling her to a hug.

"Nothing, baby. I love you"

"I love you too, Koo"

Jungkook smiles, pulling her away after placing a kiss on the side of her head.

"Okay, let's eat pancakes today?"

"Yeah!!!"

Y/n giggles, clapping her hands in excitement. Jungkook is the best and the most handsome chef in her eyes. (A/n- am I lying?)

The siblings were just playing around after the breakfast, when they heard the door bell ring. Jungkook stops tickling y/n, as he picks her up in his hands, stepping towards the door, still giggling. But his giggles slowly die as soon as he opens the door. It was his ex, HaeYoung. He caught her making out with another guy by his own eyes and immediately broke up. But she keeps bothering him every now and then, but all it was online and now, here she's, standing at his door to beg him to date her again. Although his four years old sister doesn't understand how love affairs actually work, Jungkook used to tell her about his broken relationship he had with the girl he loved the most back then, to reduce his agony. The little girl kept listening to him and comforted him, even kept it as a secret, which is quite unexpected by a four year old, they spill secrets easily, but not y/n, specially because it's his beloved brother's.

Y/n sees how Jungkook's smile drop immediately, as an angry expression cover her face. She immediately guessed that she must be HaeYoung, she's an intelligent kid. Although the girl's all attention was on Jungkook,
y/n angrily glares at her. Her brother's friend? Then the person is her friend too. Her brother's enmy? Then the person is her enmy too.

"Jungkook, please forgive me---"

"I told you to not to appear in my sight again"

Jungkook groans, as he closes the door. But HaeYoung was fast and she forcefully stopped the door from closing. Jungkook deeply sighs and she steps inside the house.

"I want to talk with you"

Said HaeYoung. Jungkook drops y/n on her feet again and holds her hand instead. He gives her a death glare, finally agreeing. Both settle themselves on the couch and y/n climbs on Jungkook's lap and Jungkook makes her sit properly, resting his huge hands on her stomach, earning a glare from HaeYoung.

"I'm so sorry, Jungkook...I---"

Jungkook rolls his eyes, giving her a done face. He has been hearing her shit since they broke up, now she's testing his patience.

"Listen, Miss.HaeYoung, I hope you already know that we are not lovers anymore. You don't have any rights to burge in my house and talk shit about you being ungrateful..."

"But, I can explain what happened that day..."

"Explanations are not needed..."

"Please, Jungkook--"

She says as fake tears roll down on her cheeks.

"....I really miss you, Kookie. I said I can exp---"

"Just shut up HaeYoung!!! Seriously what's wrong with you? I'm sure that you didn't get enough money to full fill your needs after breaking up with me isn't it? That's why you are here, begging me to get along with you again. I'm not a stupid!!! I believe what I saw, you were with another man. You hope me to trust you again? Seriously? Not even your goddamn DREAMS!!! Leave already or else ---"

Before Jungkook say anything further, y/n jumps away from Jungkook's lap, reaching HaeYoung and grabbing her hair. She pulls her hair harshly, making Jungkook astonished. Although he should stop y/n from her action, he remain there, enjoying his sister's power.

"Ahh!!! Jungkook-ah!!! Save me..!!!"

"Why would I? I could've prepared some popcorn if I knew all of these are coming"

He says as he leans on the couch more comfortably, watching the helpless girl who's getting attacked by his sister continually.

"You should know the consequences of making me angry. My baby holds such a power you know?"

"You do not raise your voice on my Koo!!! You hurt him!!! He's only mine, you cannot get him again!!!"

Y/n says as HaeYoung finally pulls the girl away, running out of the house for her dear life. Jungkook burst out for another wave of laughter, as he hugs the girl immediately, showering her face with kisses. Y/n still breath heavily, but she's happy for shoving the toxic girl away.

"My god, baby!!! You are really my sister!!! You did a great job, I'm so proud of you!!!"

He smiles again, making the girl smile too.

"Koo is mine, no one is taking you away from me..."

"Yeah, I don't think anyone can do that with this little monster.."

"Koo!!!!"

"Sorry, princess!!! I'm sorry!!! I love you and yes, I'm only yours and you are only mine"

He softly says, still giggling softly, kissing the little girl's forehead as he carries her in his arms again, approaching the kitchen to get some snacks.
