Sookan changes in many ways throughout the book year of impossible goodbyes when faced with with the following situations: when father dies, when mother turns super pale, and when Sookan and Inchun got separated from mother. The reason why Sookan changes is because when grandfather dies, she gets upset, and is very sullen. She is raging in anger at the imperial police because they chopped down grandfathers pine tree he meditates under. Sookan also changed when mother was super pale because she doesn't want to lose mother also. That changed her mood by making her super frustrated and hopeless. The last change that I wrote down was when Sookan and Inchun get separated from mother. Sookan and Inchun were super sad, so they started balling.
