You were unaware of La Signora's little.. habit when you first met. It was supposed to be a normal relationship, until you basically found out she was using you to cheat on Pantalone; again.

"I am growing tired of this. Must he keep his facade?" She spoke, bursting another one of his letters into ashes.

She was using you, and everyone knew that. And yet, you found yourself unable to not care. You liked Signora, and you truly felt for her. But did she fell the same, or was she using you?
