Reeha the Roach

Reeha the roach is a girl who, just like a roach, is always popping up and following you around no matter how much you try to get rid of her.

Person 1: Our last apartment had roaches, we had to move
Person 2: I hope the roaches weren't in your stuff and followed you
Person 1: Unfortunately it was, reeha the roach has been with us ever since
