Yurioka Yamato was eager for her first day of high school, but on her way, she encountered a confrontational person whom she tried to assist. Luckily, a handsome blond savior, Kamirozuka Jin, appeared just in time to rescue her.
Jin belongs to the most prominent Yakuza clan in their vicinity, and Yamato was forewarned to steer clear of him. Despite this, Yamato's intrigue grew upon witnessing Jin rescuing a cat by the riverside and standing stoically in the pouring rain.
Eventually, Yamato's mother disclosed a startling revelation: "That boy was responsible for your father's death." With so much at stake, Yamato resolved to uncover the truth behind her father's demise, venturing closer to Jin in the process.
As the offspring of a Yakuza leader and a policeman respectively, Jin and Yamato would have never interacted under different circumstances. The outcome of their romantic conflict now rests on determining the veracity of this hidden truth.
