It Was Me, Not You

Diana is an illegitimate child who is said to be the only stain on the entirely honourable Archduke Teravita.
“Don’t even get close to this kind of thing again. This is not the place for a thousand different things like you.”

The Archduke somehow thought of his dead wife whenever he saw Diana, but in the end he turned away from her.
