their parents immigrated from korea in the 70s and had a son and two daughters. i've said that the sister is 31 or 32 but i am open to changing that. basically the dad died in 1992 in a car accident and the mom eventually remarried and he adopted the three kids. he also had a son from a previous relationship and he and their mom had one daughter. they are all very tight knit and have group texts, get together for family brunch on sunday, and genuinely love each other even when they are fighting. the dad is an ex marine who retired about five years ago and the mom is a homemaker who is very traditionally korean and not always the most affectionate woman due to having been through a lot in her life.
