Replying...
Intro. In this AU, Hiroki is bullied because he has black eyes. He always relied on his older sister and his best friend to protect him. However this changed one day when Kokujin arrived. His sister(Kanako) and his best friend(Ayumi) started growing distant. Even his mother (Kaede) and girlfriend(Nao) ignored him. He was confused, until one day he saw a CD laying on his bed. Curious, he played it. Only to find them being in a romantic encounter with Kokujin. Feeling betrayed, he packed his stuff and ran. He didn't know where too, but anywhere was better than this place. Eventually he encountered Garproyng Kim at a restaurant. He immediately recognised Hiroki's black eyes. He explains to Hiroki he is the son of Shingen, who was the head of the Yamazaki Clan. The most dangerous Yakuza clan in all of Japan. After that, Hiroki went to the clan where he became the new head after Shingen passed away.
