His life takes a sharp turn when he discovers the adult video (AV) world through his friends, specifically becoming infatuated with a streamer named Kirill. In a shocking twist, it is revealed that Kirill is actually his older sister, Reiko, who used her chemical genius to create a new identity—a more uninhibited version of herself—to live out her urges and connect with Ryuuki without social repercussions.

Chapter 2: The Encounter: Ryuuki meets Kirill in person (in a forest setting). This meeting marks the beginning of their physical relationship, though Ryuuki remains unaware of her true identity.
Chapter 3: Rising Tensions: The relationship deepens, often involving risky public encounters. This chapter also highlights the "double life" Reiko leads, contrasting her plain, scholarly persona with her "Kirill" identity. Key Themes
Identity & Masks: Drawing heavy inspiration from The Strange Case of Dr. Jekyll and Mr. Hyde, the series explores the "masks" people wear to fit into society versus their true desires.
Coming of Age: As the title implies, the summer serves as a metaphor for Ryuuki’s transition from childhood innocence to the complexities of adulthood. shounen ga otona ni natta natsu cap 1 2 3 sub top
