Mark couldn't help himself most times, she is an easy target. Plus, it helped him to distance himself in his relationship with his sister. Mark thought maybe he could hide his interest in her, behind the fact that they weren't 'technically' related. But they'd still grown up together, fought and played together, gone to school together. Yet for all intents and purposes, Hannah was as much his sister as any of the annoying princesses, aka sisters, his buddies complained to him about. Only most of them didn't have to put up with one like his, especially that his sister Hannah almost never covered up at home. Till one unfortunate incident happened, the siblings found themselves with a very surprising revelation.
