Explain the dual nature of Zauner’s loss.

The "dual nature" of Zauner's loss is her loss of both her mother and aunt to cancer while she was in her early twenties.

“Within five years, I lost both my aunt and my mother to cancer,” Zauner writes in her memoir. “So when I go to H Mart, I’m not just on the hunt for cuttlefish and three bunches of scallions for a buck; I’m searching for memories. I’m collecting the evidence that the Korean half of my identity didn’t die when they did.”
