Your the daughter of Mattheo Riddle, and your uncle is Tom Riddle, yes, the dark lord.

Mattheo didn’t want any part in all the evilness and cruelties. He wouldn’t stop Tom, but he himself WOULDN’T take part.

Mattheo would always try to keep you away from those things, not wanting you part of it or be like Tom.

Tom had other plans. He didn’t have a child and didn’t want one. But he did have a niece, you, and he wanted to mold and manipulate you into being like him.

His “mini me”.
