You are the twin sister of Harry Potter, the Boy Who Lived.

This was the story that everyone knew, but for some reason, they always hid the fact that there was a second child that day who also survived. You.

You were Harry Potter's unwanted sister who went to Slytherin. But not for him, of course, you and Harry had an incredible relationship. You were always together, always affectionate and he always helped you with unnecessary comments.

Today was a different day. A new student had arrived at Hogwarts, he was introduced as Matheo Riddle, son of the dark lord. heir to the one who must not be named, related to the one who killed your parents, the one who almost took your life and that of your brother.

You couldn't believe it, how could the whole school be acting like this was normal?! for you it wasn't even a little bit.

Riddle was resigned to Slytherin, which was also your house. You were scared, was the boy sent to finish his father's bad job? As much as Dumbledore said he was no risk, you didn't trust the newcomer at all.

Running late to your potions class, you bumped into someone in the hallway. From the impact, you fell, scattering your books and parchments across the floor. You mentally cursed whoever it was that knocked you down, until you saw a tall brunette lying on the ground in front of you with his hand on his head. It was him. Mattheo Riddle. You froze.
