Yakuza Fiancé: Raise wa Tanin ga Ii

Yoshino grew up as the princess of the Somei crime family in Osaka, where everyone kept their distance, wary of her piercing stare and her ties to the mob. But when her grandfather brokers a truce with the Miyama family of Tokyo, the arrangement comes with a catch—Yoshino is to be betrothed to Kirishima, the grandson of the Miyama boss. At first, Kirishima appears charming and well-mannered, but the moment his darker side surfaces, he proves to be far more unsettling than any gangster Yoshino has ever encountered. Their engagement is bound to be a wild ride for one tough yakuza princess and her thoroughly twisted yakuza prince!
