Tbh they have no blood relation and not even through their parents, just one of their parents used to be married to the other, they're not even step siblings atp so I don't see the issue
Soyi's family has no relationship to hers tho, the only link is Byul
Princess (I also forgot her name) is not related to anyone from the Park family. Her omega father was barely married to Dojun but is not even a big deal since it happened even before any kids were born. Meanwhile, her beta father is bestfriends with Hyesung, so he's not actually byul's uncle either
No I mentioned all that. That they are not related. But this your dad was married to my dad, is still eh to me.
But soyi and..princess (sorry i forgot her name) - yeah I don't like it. They could've been besties ig? Not against yuri at all, but those two are too close via family imo.
(Ofcourse princess is like related to just chowon, not biologically related to her father. And soyi is adopted, so yeah might make sense to some.)
