Yakuza Fiancé Vol. 1

Yoshino grew up the sheltered yakuza princess of the largest crime family in Osaka, the Somei. Due to her resting bitch face and dangerous family, no man has ever approached her. When her grandfather signs a truce with the Tokyo-based Miyama crime family, he offers her up as a truce bride to the Miyama leader's grandson! Kirishima Miyama is popular, charming, and seems totally normal.
