Final answer:
Without context it's difficult to accurately answer how Keiko is treated; the question likely relates to a character from a story set during World War II.
Step-by-step explanation:
The question appears to relate to a character named Keiko from a story or novel. Without additional context, it is challenging to provide a specific answer. If Keiko is from the novel 'Hotel on the Corner of Bitter and Sweet' or a similar narrative set during World War II, her treatment by others after staying in Camp Harmony might reflect historical attitudes and social dynamics of the time. In such a story, characters like Keiko, after returning from internment camps, often faced a range of reactions from the community, from prejudice and teasing to sympathy and kindness. However, without the proper context of the specific work or the events of the narrative, a definitive answer cannot be given.
