Yuri is a determined 20-year-old college student searching for romance when she stumbles into an unexpected encounter at a party. She crosses paths with Ouya Toshiomi, the charming yet dangerous underboss of the Ouya Syndicate. His small act of kindness towards her—a coat and a business card—leaves Yuri smitten.

When they meet again, the chemistry between them is undeniable, but it is also clear that Toshiomi's world is anything but safe; the glamorous life of a yakuza consort comes with luxury, gifts, and deepening affection, as well as living with constant, personal threats to her life. Despite all the risks, Yuri passionately resolves to be Toshiomi's lover no matter the cost.
