Yes you are right. But actually, we know very little about ourself in the game. There are a lot of things to discover in our journey, that's because I guess that in the future there will be possible this scenario too. Let's see what future updates will bring us ☺️
They give you an option to say if you want to impregnate/be impregnated by others and there's literally hakkon. It's safe to say there will be pregnancy in the game, just not right now.
When you talk to Arthur about pregnancy, you have 3 choiches. If you choose that you want to be impregnated, he mentions Hakkon. But I don't know maybe you are right and there will be no pregnancy at all. We'll see. For the moment, I can't wait the next update 😍
