yes! so the parents were south korean immigrants who came to the states in the late 70s. there are four children from that marriage - your girl would be the second oldest, then there's a brother, and grace. the oldest sister will probably remain a npc. the parents had a very toxic relationship and the dad wound up leaving when grace was one. a few years later the mom met another man (he was a widower and had three kids) and they got married. they are sort of like the modern day brady bunch. she would have grown up in boston but could be based anywhere now.
