"Seokjin: Ok then this is my younger sister, she will stay here with us"

"Namjoon: Introduce yourself, little girl" he said softly.

"Yoongi: Anyway, we'll be together for a while so don't be shy" he said coldly.

"Hoseok: Maybe she's shy, it's okay"

"Jimin: Hey, she's even shorter than me" he smiled teasingly.

"Taehyung: Hey girl, don't be shy, eat more"

"Jungkook: Thanks to her today, we have an excuse to drink" he laughed.
