kpop boyband mixes

An girl called Y/N has known jisung, wooseok, benji, j. Jin, Jackson, namjoon, moonbin, kai, g-dragon and heechul from all kinds of boyband for over 16 years. She first met them and 1 year old and has known all 10 of them ever since. This year is Y/N's 18th birthday, but she doesn't know what she is in for. All of her 10 closest friends have something in store for her and it includes their bandmates but does she know what danger she could put herself in?
