as much as i love the idea/headcanon of manfred being an absolute disappointment of a father to both franziska and miles (mainly miles), another idea i love but barely see is von karma being a good father to them all throughout their childhood. the 'perfect' father, even. what if he had high expectations of their grades, but overall was seemingly perfect father to miles and franziska. supporting their interests, praising high marks, showing affection to them, etc.
with miles specifically, what if he helped him through his DL-6 nightmares? showed genuine pride in miles for becoming a prosecutor?
its a silly thought but still
