The kids were legally adopted since the deadbeat dad gave them up. Maybe its because I have more modern non-conservative American values but I don't see how a deadbeat screaming that they are the biological father who gave the kids up for adoption would be a scandal?
I think it's not the fact that a deadbeat cunt is yelling like a retard that's the problem here. That in itself can be safely ignored by everyone.
What can't be ignored is the fact that they're all adopted and thus, are not Kaname's real children. Realistically, in the grand scheme of things it doesn't change much but you know how some "news" outlets love to chase after even the smallest scoop.
Right now, I think most people are not looking at this as clearly as they should.
To them right now, the fact the richest man on the planet has 8 adopted kids and hid them till now is some sensational shit, and ngl it would be irl too.
But what you're forgetting to take into account is that you're taking this from your own point of view and not theirs. That I know of, you're not a superstar, neither are you filthy rich. You're not being constantly trailed by paparazzis or always given looks by everyone on the street since the whole city literally knows your face purely due to being connected to the richest man on earth.
In almost every chapter where they're outside, people almost always recognize them. They are that known.
Now put yourself in a shitty outlet's shoes, like TMZ or some other bullshit. You know that there are these 8 sensational kids, people love to gossip, and they're super known throughout the city (if not country). Now it's out that they're adpoted, it's gonna get people talking and now you want to milk the absolute shit out of this story.
Hence the "scandal" part since now they're under intense scrutiny by "journalists". A single misstep can fuck them all sideways, putting real pressure on them.
Still, it's true that in the grand scheme of things, to the average joe this is just some shit you'd see on insta, go "eh, really? That's insane" then just keep doomscrolling. But to the Shiunji kids, it's everyday like this. These paparazzis will chase after the faintest trail of dirt they can dig up.
I do get though how from our point of view it can seem over the top and shit like that. Even I still think a bit that this is overblown. But I also kinda get why they're calling it a scandal.
And honestly, it's not really properly explained by the author. So even all I'm saying is purely theoretical. I could be blowing pure smoke out of my ass right now lmfao
