Chihaya Kisakinomiya, born Chihaya Mikado, seeks refuge at Seio Girls' Academy under his mother’s maiden name after relentless bullying and harassment at his former school triggers truancy and deep-seated distrust toward men. His mother, unable to bear his suffering, orchestrates his transfer to her alma mater, where the institution’s all-female policy forces him into crossdressing.

Blessed with an androgynous physique, silver hair inherited from his grandmother, and striking violet eyes, Chihaya’s ethereal features and poised grace let him pass effortlessly among students. Intellectually brilliant, athletically adept, and artistically accomplished in piano and ikebana, he ascends as a revered figure, admired for his kindness. His gentle, nurturing nature—manifested in tutoring peers, tending to the sick, and offering unwavering support—cements his status as a beloved role model.

Chihaya’s journey is marked by a fraught relationship with his concealed identity. Initially resisting his mother’s scheme, he gradually adapts with aid from his loyal maid, Fumi Watarai, who meticulously upholds his facade. Central to his growth is Kaoruko Nanahara, the sole student privy to his secret, whose friendship evolves into a profound emotional bond. Their connection deepens amidst clashes between Chihaya’s hidden truth and societal pressures.

At Seio, Chihaya grapples with shadows of past trauma while facing newfound trials: unexpected adoration, leadership duties as an elected Elder, and the weight of maintaining his dual existence. His path weaves through reconciling fractured identities, forging authentic bonds despite deception, and confronting unresolved tensions with his mother, whose decisions loom over his life. Through these trials, he transforms from a guarded, isolated soul into one learning to embrace vulnerability and trust within the confines of his intricately constructed world.
