Are you insane? How can any sane civilized person even think of doing that!
Your dad and mom have more experience. Whatever they say does have reason and logic behind it. Blood bonds are blood bonds, his wife till she doesn't give birth to his child is not completly counted as an absolute family member.
depends on the parent. not all parents care about their kids, a lot of parents have a preconceived notion of what they want their child to behave like and succeed at and won't accept any alternative even if it's making their child miserable. some parents outright hate or resent their children and act against their best interest purely out of spite. there are parents who genuinely don't deserve filial piety, granted i do think his dad has SOME redeemable qualities even if he acted way out of line in this chapter
reducing her to an object by saying "you-know-who", "her" or "she" instead of her name is petty and rude on top of suggesting his son break up with her despite them having a loving relationship and his son considering marriage and children with jiang he. to the dad's knowledge, she's an abused orphan with nowhere to go and nobody to rely on except her son and has up until this point been desperately been working in sweatshops to survive and feed herself. now she has finally found stability and happiness, even getting a form of education, and he wants her son to abandon her at the side of the road because getting an id is tricky? even if it's some sort of test and not his actual thoughts, that's beyond shitty
