Final answer:
Without access to the specific text of the novel "Hotel on the Corner of Bitter and Sweet," no accurate answer can be provided regarding Henry's secret.
Step-by-step explanation:
The question appears to refer to the novel "Hotel on the Corner of Bitter and Sweet" by Jamie Ford, where the character Henry reveals a secret to Keiko. Unfortunately, the provided references do not contain any specific information related to Henry's secret in the context of the story.
