The mother is not mentally prepared to acknowledge the fact that her daughter is dead is good that the mc took that boy alway from her she might keep trying to make him live as his dead sister that’s why he killed his mother he couldn’t take it anymore

It is explained that the father doesn't want anything to do with them. I assume he hasn't told any of his family about his children or he's telling lies. Her family if I remember correctly "sold" her. (chapter 91 page 32 last bubble) I'm not sure if it was a miss in translation but it would explain why her family doesn't do anything.
He’s over here being all in love with that roach but he gets irritated when the empress talks to any guy like what ? Get it together do you love the empress or you don’t
Clearly not. I dont even think he loves RATsha considering how she ended up.
As navier later says he has always been a child and never grew up.
Yes I agree maybe not love but like he doesn’t like people touching the “things that are his” even though he doesn’t love the empress
