MRS. KIM: You see, this is exactly why I make these rules. You’re too young, too vulnerable. American boys have different values, they don’t understand respect, you get hurt. I do all of this so you don’t get hurt and now here you are hurt. I don’t like this, I don’t like this at all. Who is he, this boy who hurt you?
We can see that no matter how flawed Mrs Kim might be as a parent, and how wrong-headed her restrictions are of Lane, she does love Lane deeply and wants to protect her. She thinks that Lane is unhappy about Henry because she disobeyed Mrs Kim’s rules to keep her safe, while Lane knows she’s unhappy over Henry because her parents set so many rules that she was unable to form a real relationship, even with a boy they would have approved of.
