Which is always the cause of speculations on which side and you don't really mind, because it means people are relaxed enough to spend time with stupid theories. Ghost wonders, if it bothers you, but you just kiss him and tell him it's cute that he cares. But you don't let him "defend your honour" or anything stupid. You have to much fun listening to the newest stories about your origins.
Orcs and humans have been in relationships forever, since you are not that different and obviously able to produce offspring.
It gets even funnier when König appears one day, and instead of introducing himself he hugs you tight. "Why didn't you tell me you got a husband now. Do you not care about your Teddybär anymore?"
The rumours go wild, the most popular being that you're married to König already but left him to find another man. It's all fun and games until some soldiers think they have to play the moral compass and let you know that cheating is never okay.
"He is my brother, you morons. Half brother, but still. We have the same nose!" You laugh, only half angry.
Well, given the fact that most people never see his face, it is understandable that the familiarity wasn't that obvious.
You still don't tell anyone which of your parents was human.
