During their conversation, Tengoku perceives Aoki's facade as an exemplary teacher and reveals that he has been observing him since he arrived at the school. He criticizes Aoki’s naivety and unexpectedly kisses him, leaving Aoki flustered and unable to refuse. This encounter prompts Aoki to recall childhood memories and confront his true self. What lies ahead for the timid Aoki? Will he find himself in heaven or hell?
