logically, it would go from the eldest child to the eldest, since it’s literally passed on like an object that only one person can possess at time, and other like ml can connect to that. But then again, that’s our cultural heritage, where the eldest inherits everything - from fortune to curses. Though if I’m not mistaken, there only women were carriers of the curse, which is… yeah.. Hm, mb there will be explanation of curse origin, don't remember if there was one?
It reminded me, Weasley family from H P desperately tried to have a daughter, and that was hella pain in the ass. But again, we don't have curse origin, Karen suspiciously looks like her mother, almost identical, mb it's programmed like that - only one daughter per generation. Im guessing mc will break from the curse completely, for t child future somehow, and investigate in process so we don't have all this questions

Lowkey spoilers
I was thinking while reading, cause it seems like all the other women in the family tree literally had one kid then were like "yeah we r good" since the curse moved on
What would have happened if the mom had another kid? Would it have went to them or would it stay with Karen or would they share it? There are questions I have that I need answered
