How do you think the Sakamakis would be as parents?

I know this might sound like a silly question, but I got curious. We all know Karlheinz is all about the Adam and Eve project, and having grandkids is a big deal for him. Realistically, if the franchise wasn’t an otome game, this probably would’ve happened already.

So, it got me thinking—how would they actually be as parents? I know they’d all be bad in their own way, but it’d be fun to think about the dynamics. What do you all think?
