Mi prometido yakuza, 1

Yoshino is the granddaughter of Osaka's most powerful mob boss and has always been treated in a privileged manner. But a pact between her grandfather and another big Tokyo mobster will turn her quiet life upside down. Kirishima, the grandson of the Tokyo gangster with whom Yoshino is supposed to end up engaged, has little or nothing to do with the image he shows and he will not be able to deceive the young Yoshino, a woman of arms who will not be willing to succumb to this masochist.
