Tom Riddle was your father, and just like you could imagine him as a father he was; cold, evil but also protective atleast with you.

Your father wasn’t very fond of your older brother Mattheo Riddle despite him always wanting a son. However when you were born, his daughter, he LOVED you. You were almost his little clone, his mini me. He adored you, you represented him so much

He’d always spoil you more.Your mother was dead, as Tom didn’t even love her, he just wanted heirs from her(kids)
