Polar Opposites || Regulus Black

She was a Hufflepuff, he was a Slytherin. She was Emily, he was Regulus.
When the fate of the whole world lies on one girl's shoulders, she has no choice but to confide in someone else.
It was just that no one expected it to be Regulus Arcturus Black.

All rights to the harry potter universe go to JK Rowling, including her locations and characters. I only own my original characters and locations.
