Yayoi grew up in a wealthy household as the daughter of successful business owners. Following her parents' wishes, she graduated from an all-girls school, worked as a secretary at a trading company, and at age 24 married the heir of an affiliated company through an arranged introduction. She raised two children and lived a peaceful family life. However, she harbored a secret she could never reveal—trauma from a rape she experienced during adolescence had left her with severe gynophobia, making her deeply averse to sexual intimacy. That changed when she met a certain man. Through him, she discovered the pleasures of sex, awakening to a new world and beginning an entirely different life.
