In the world of the yakuza, Gō Kiritani, a capable young enforcer, is assigned a most unusual task: to serve as the caretaker for Riyo Washizu, the sheltered daughter of the powerful crime family that controls the Kanto region. Gō expects a typical heiress, but he soon discovers that Riyo harbors a specific and intense fetish, a taste she and the series call yowarer. She is sexually aroused by watching strong, capable men in moments of weakness, injury, or vulnerability. Every time Gō sustains a minor injury or shows physical strain, Riyo becomes visibly flustered and excited, turning his duty into a gauntlet of awkward encounters. Gō finds this fixation bizarre and frustrating, especially as Riyo's eagerness to tend to his wounds and observe his weakened state only amplifies his irritation. The story unfolds as a forbidden romantic comedy set within the rigid codes of yakuza hierarchy, following the daily friction and growing, complicated bond between a duty-bound enforcer and an heiress with an unusual sexual appetite for his fragility. The narrative explores their clashing personalities and the increasingly strange situations that arise from Riyo's obsession, turning the power dynamics of their relationship on their head as Gō must navigate her advances while maintaining his professional distance.
