Yakuza Fiance: Raise wa Tanin ga Ii

Yoshino Somei, a 17-year-old from Osaka, moves to Tokyo to live with the Miyama family after her grandfather arranges her engagement to Kirishima Miyama, the grandson of the Tokyo yakuza group's leader. Kirishima initially presents a polite exterior, but Yoshino discovers he has a masochistic personality and enjoys being hurt emotionally and physically. Kirishima's goal is to have a fiancée who will make his life miserable, but instead, Yoshino decides to take a more personal approach by making Kirishima fall in love with her and then ending their engagement.
