   Summary

   Being an idol's little sister is hard enough when you're constantly bombarded in comment sections by fans begging for numbers.
   It gets harder when you take him up on his offer to stay in his dorm alongside his 6 other extremely attractive members.
   Shit gets complicated when you figure out 4 of his bestfriends aren't opposed to you getting down and dirty with them.
