When feisty college student Yuri is attacked at a party, she's saved by Toshiomi Oya, the underboss of a yakuza syndicate. Despite her obvious attraction to him, she convinces herself that she's not in the market for a bad boy type. But when they meet again, she finds herself irresistibly drawn to him--kicking off a steamy and dangerous love affair that threatens to consume her, body and soul.

Yuri has abandoned her family and friends to be with Oya, the man she loves. Just as it seems the star-crossed pair will achieve their happily ever after, however, Oya's mother thwarts their plans. Deeming Yuri an unsuitable partner for a yakuza, she demands that Oya enter into an arranged marriage instead. Can Oya and Yuri overcome the objections of the Oya syndicate's absolute authority?
