Ep. 3: Kaori shares lunch secrets with Shogo, who helps her retrieve a forgotten diary and aids her memory recovery.

Kaori starts preparing lunches for Yuki while documenting his preferences. Yuki invites Shogo to review her secret regarding her memory loss, which initially intimidates Kaori. Although Shogo offers skeptical theories that strain his relationship with Yuki, he later retrieves Kaori’s forgotten diary and encourages her to communicate directly with others. After school, Kaori is distressed by classmates’ mockery until Shogo intervenes. The following Monday, a math problem triggers Kaori’s recollection of eggs she made for lunch. Shogo follows the pair and, noting her recognition of him similar to her family, concludes they are not friends. This deduction leads him to accept her story, while Yuki remains highly optimistic about her improving condition.
