Yurioka Yamato has been looking forward to her first day of high school. On her way there, she got into trouble with a person she was helping but was then saved by a blonde hottie.

His name is Kamirozuka Jin, son of the largest Yakuza family in the area.

She was told to never get close to him but after seeing him rescue a cat by the riverside and also seeing him standing alone in the rain, she cannot help but be curious about him.

Then one day, her mother gave a shocking confession:

"Your father... died because of that boy."

Is that true? Why did he kill my father? In order to find out the truth, Yamato decided to get closer to Jin.

A son of a yakuza and the daughter of a policeman. Two people who would otherwise never have crossed paths. The truth that lies between them is now hanging on this love battle!
