Not Ideal; JJK

Yoon Rin So (Rinso or Rin) is an outgoing girl who loves to joke around and not take anything seriously. Jeon Jungkook is a hard working idol who does joke around sometimes but, unlike Rin So, prefers to be serious. Rin So and her younger twin brother Min Ho move to Seoul after graduating high school to be with their cousin whom they love very much, Park Jimin. When Jungkook meets Rin So he doesn't take a liking to her attitude.
"She's like a 2-year-old! There's just no sense in anything she says." he commented with a frown.
"Jungkook, she's our Hyung's cousin deal with it for a while, okay? I think she's just like Hobi Hyung."
Jungkook sighed, glancing in Jimin's direction, seeing his Hyung happy while being with his cousins made him happy "Fine, but I'm only doing this for Jimin Hyung." Taehyung patted the younger boys head "Good boy."
