Hanasaki Sono is a 32-year-old manga artist known for creating hentai and ecchi manga aimed at male readers. His feminine features, including blonde hair and brown eyes, frequently cause others to mistake him for a woman. This initial confusion extended to fellow mangaka Seiji Yamada, an admirer of Sono's work. Despite this misunderstanding, Yamada developed romantic feelings, leading to a relationship between them.

Sono's history involves a pattern of short-term sexual encounters and promiscuity. This behavior stems from deep emotional trauma caused by repeated experiences of abandonment and feeling valued solely for sex. When Yamada learns about this past, it creates significant conflict, resulting in a temporary separation due to Yamada's distress and insecurity regarding Sono's sincerity.

In relationships, Sono displays a passive and accommodating personality, often prioritizing his partner's needs above his own. After years of transient connections, he deeply desires a meaningful, committed bond. Following the separation, Sono reconciles with Yamada by revealing the full extent of his emotional damage and vulnerability. This honesty allows their relationship to rebuild on a foundation of mutual understanding. Professionally, they collaborate on manga projects, intertwining their personal and creative lives.
