Being the heir to a yakuza clan has its benefits. For Takanari Saeki, he gets to live with his best friend and attendant, Ayano Takahara. As enjoyable as their time together is, however, Takanari has no interest in succeeding his grandfather and hopes to live a normal life.

Things become uncertain for Takanari when his grandfather introduces Madoka Tsumugi, heir to a subordinate group, and a potential replacement for Takanari if he truly does not want to work in the family business. While Madoka inserts himself into Takanari's once-carefree life, transferring to his high school and taking away some of Ayano's attention, Takanari has to decide what is most important to him—his dreams of a normal future, or his relationship with Ayano.
