Y/n is Namjoon's little sister. She is 17, a well-known professional boxer, and has an Olympic gold medal. She is also a supermodel and known worldwide as Anna Wintour's favorite. Your parents decide to take you to live during summer break with your brother, Namjoon who lives with the other members of his group, BTS.

Your parents saw this as a good opportunity to spend time with your brother who you don't see often because he is busy and so are you due to modeling and boxing.

"You're gonna love them. They're all very nice." Namjoon says with a sweet smile that marks its dimples. He gets Y/n's suitcase as he leads her inside the dorms. The members all knew Y/n obviously due to her being well-known for boxing and modeling. They had been waiting to meet her ever since they got to know from Namjoon that she was gonna be staying with them for the summer.
