Kiritani accepts what should be an straightforward assignment: watch over Riyo Washizu, daughter of a rival yakuza chairman, while the two crime families maintain an uneasy peace. The job seems manageable until Riyo reveals her particular weakness. She's drawn to powerful men in moments of vulnerability, finding attraction in strength surrendered. What begins as a protective duty transforms into something neither of them anticipated when Riyo starts deliberately putting Kiritani in situations designed to test his composure and expose his softer side. The gap between Kiritani's tough exterior and what Riyo wants to discover beneath it becomes the heart of their dynamic. He's caught between maintaining his reputation as an intimidating yakuza and the impossible task of protecting someone whose interests seem designed specifically to break through his defenses. As they navigate this strange arrangement, protection blurs into something more complicated. Comedy erupts from Riyo's brazen tactics and Kiritani's escalating embarrassment, while genuine connection grows between two people who shouldn't work together at all.
