The man I met was more dangerous than the yakuza.

Somei Yoshino, a high school girl born and raised in a gangster family.
Even though the family environment was special, we lived a quiet and peaceful life.
But Yoshino's life changes dramatically when she meets her fiancé, Miyama Kirishima!
Kirishima, who appeared to be a handsome and kind man, was more of a yakuza
He was a scary man!

The craziest love story ever created by unique people begins!!
