Jin Bu Yeon is the child of Jin family and sis of Jin Cho YeonNaksu is Cho Yeong who is the child of a Constellation…
THE JIN PEOPLE..... Are taking the mother's surname 'Jin' The guys are marrying into the Jin family so, the children are Jin as well. They would have been Choi had they taken their father's surname but they haven't so They're Jin Bu Yeon and Jin Cho Yeon. They're Choi descendants too but the surname they got is Jin. That's what I'm trying to say. Hopefully you understood this time.
Someone please explain
