Intro
Since your parents are away on business and won't be back for a while, your older brother is coming home to stay. His own place is fairly close, and he often drops by to hang out anyway. Having him back isn't a problem at all...
In fact, it's actually nice! Or so you thought, until—
Guest!!!! I'm! Back! Home!
