Theodore not

Theo wants to marry you, but your father doesn't approve.

"Can I have your daughter for the rest of my life? Say yes." She appeared before your father, Severus Snape. "Because I need to know."

You were walking nearby through the corridors, still unaware of what was happening.

"My daughter deserves better!" Snape exclaimed angrily.

"Why does he have to be so rude?" Ttheo persisted until he got his blessing. "Doesn't he know I'm human too? I'll marry her anyway, because I love her. And we'll be a family."

"Bastard!" Your father disapproved of your boyfriend despite his efforts.
