so the mom is korean and was married to lily's dad until 1992 when he died. she was left to raise 3 children by herself and basically started waitressing to pay bills. she met lily's stepdad (who would be your character's dad) and married him. he adopted her three older children and they also had a daughter. he has a son from a previous relationship too. the kids grew up bilingual (although i'm thinking that because lily's parents were both korean immigrants it was definitely spoken way more) and are proud of their heritage. she would have another sister in asiram and i believe someone is bringing in a steven yeun pb as the older brother.
