Yuko Imai, nicknamed Kaoru, is a driven talent manager balancing professionalism with a tangled romantic and sexual relationship with Kaori, an intersex pop idol she discovered on the streets and molded into stardom. Their bond hinges on protecting Kaori’s concealed intersex identity, a secret Yuko fiercely guards to secure her protégé’s career.

Yuko’s past is shadowed by shared trauma with former ally Saki Midorikawa—both endured exploitation by record executives during their early idol careers. After a vocal cord infection shattered Yuko’s singing aspirations, she vanished from the industry without closure, leaving Saki embittered. Years later, Saki resurfaces as a vengeful rival, targeting Kaori’s hidden truth to destabilize Yuko’s carefully constructed world.

As Kaori’s manager, Yuko operates as both strategist and shield, countering threats like Saki’s blackmail. When confronted with a manipulative sexual challenge engineered by Saki, Yuko engages in tactical maneuvering to outplay her adversary, drawing on her fraught history to protect Kaori. The clash compels Yuko to revisit her abrupt exit from music, disclosing the truth behind her shattered voice to Saki.

Pragmatic yet emotionally reserved, Yuko’s defenses were forged in exploitation’s crucible. Her dynamic with Kaori intertwines mentorship, romance, and necessity, with Yuko consistently choosing Kaori’s security over emotional exposure. Lingering scars from her abuse and the unresolved strife with Saki fuel her struggles to trust and connect, framing her every calculated move in a world where vulnerability risks destruction.
