She navigates complicated relationships with two men: Yoshioka, a calculating businessman who offers financial security, and Segawa, a kabuki performer she passionately desires. Through betrayals and rivalries with other geisha, Komayo struggles to balance love, loyalty, and her quest for independence in a world where emotional detachment is survival.
