He knows or have strong suspicions that she's a dragon when he got the ring back on that chapter it must have showed some of her inherent abilities
She also seems knowledgeable of many subjects and is good at decision making (that's because she is a transmigrator but they don't know about it, for all they know she's a genius)
But yeah he is colder with the boys but it may be because he is a widower?(not a good excuse tho)
Well alls well thats ends well, because Eirin is (spoiler)
.
is his biological daughter. The wife died because Eirin is a powerful dragon. (according to the spoilers that I've read)
How's that a good ending? So, because she is a genetic offspring, it's okay to neglect the other kids and subject them to emotional abuse? So, you can forgive him for not fulfilling his responsibility towards those kids as their parent now that you know that the daughter is genetically related to him? Toxic and neglectful parenting that her brothers went through was only a problem for you as long as you thought she wasn't genetically related to him? Some sketchy principles you've got there.
We really need society, in general, to get its head set right because it's disgusting, immoral and inhumane now normalised it is for everyone to treat adoptive families as inferior and second fiddle to genetically related ones. People really need to adopt more. In fact, I would go so far as to contend that if one is interested in parenthood and has the means to raise children in a healthy and secure environment, they should look to adoption as a first choice instead of defaulting to genetic reproduction. At this point, you don't have to worry about the species. There will always be far more people, far less privileged, who will be producing sufficiently enough offsprings that humans won't die out if you didn't help out, too. What we need is enough human resources and material resources to raise those children in a comfortable and caring environment that helps them into healthy, well-adjusted and capable adults. That's where the more privileged of us have a role to play.
I don't know why but it looks to me now Father favors Eirin more than his sons. And going thelong way to give the head title to her instead of your sons? Let's be honest. If it was reality, adopted kid getting the title instead of sons, that'd cause a war and hate :/ I like how father is protective of Eirin but favoring her more than his sons? At this point, it might look like sons might end up become sacrificial objects for her to stand high in status. But still, I will wait for the next chapter and see. Hopefully he explains his reasoning.
