What do you get when you're Key's sister? Living in a house full of idols, meeting hot, y boy groups, going around the world, and most of all...getting chased by crazy fans trying to kill me. I don't think I properly introduced myself. I am Kim ____, I am 19 years old, and I am Kim Kibum's sister. Yes, THE Kim Kibum, the most annoying, diva whose nickname is Key. Yes, unfortunatey, he is my brother. It might seem really fun, but trust me, It's not! But, after all, he is my brother, and I do love him....Wow that was cheesy.
