Comment by Galactic Navy Officer on Another World Territory Reform ~Starting Public Works with Earth Magic~ - Chapter 22

@Galactic Navy Officer I think it made sense though. Think about it. The kids would not accept her as a mother in most situations that quickly... it usually takes time. For a noble of that gramps standing, he would never waste his time on something like that if there were other blood related options. The second problem is regarding possible feuds for the right of succession of the family as heir. It's too much of a problem for an obtuse old man like him... that's why he told his daughter to abandon the kids of the other wife.  

This just shows how freaking amazing the step mom was. She was going against the wishes of her father, a noble of higher standing, and even against the children being wary of her as a mother. Even compared to situations nowadays on our own world, it's a really complicated manner to handle...

@B P (Ult1m4) It's the "adopted out" thing I'm having an issue with. You adopt out kids without parents. The kids' father was and is very much alive. There's no reason whatsoever to adopt them anywhere.
