Sookan also seems to try to be more helpful starting after mother was gone. "Aunt Tiger was bust trying to cover for Mother at the sock factory, and Inchun and I did what we could" (49) Sookan and Inchun try to help in whatever way to keep the family out of harm's way.
Sookan was more thoughtful after the Russian's attempt to brainwash everyone in North Korea.
"I sang out loud and was happy until I looked over at Mother and Aunt. I realized that they were barely mouthing the words". (108). The brainwashing almost worked on Sookan, and was working for a period of time, but when she saw Mother and Aunt Tiger not seeming happy, she realized they were trying to brainwash them.
These changes in Sookan's struggle to survive made Sookan be a more positive, helpful, and thoughtful person. These characteristics make people in the real world be more happy, make good choices,be more observant, etc.
