Harry met Holly when she was two - abandoned in the park by her mother. Unable to leave her alone, he stayed behind to keep her safe. Over the years, they became as inseparable as brother and sister.
When Harry found out he was a wizard, he was happy to find that Holly was a witch too, and one day, she would enter his new world with him.

Finding out he was a father to a nine-year-old girl, Severus Snape didn't hesitate to bring her home. His daughter belonged by his side, after all. Finding his daughter preferred Harry Potter over him was a travesty the Potions Master was not going to tolerate.

Somehow, Severus had to make his daughter see Harry Potter as he did - worthless, useless, hopeless.

Cauldron’s bubbled. Potions simmered. And Snape was yelling at Neville again. Just another ordinary day in Potions class, or so they all thought. When a potion reveals something out of the ordinary, Harry’s life is changed forever, and not in a positive way. Was it so unreasonable to ask that he be allowed to make it through sixth year like a normal teenager?
