A Chinese American boy who becomes the novel's central case study in assimilation's cost. Jin's trajectory — from lonely new kid to self-hating teenager to a boy who literally transforms into a white person — is Yang's anatomy of internalized racism. Danny is not a separate character but Jin's wish fulfilled, and the fulfillment is a prison. Jin's journey ends not with triumph but with a boba tea and an uncertain conversation, which is more honest than any Hollywood resolution.
