Zetsurin Yakuza no Gokujou Aibu Nogarerarenai Keiyaku Kekkon

At 28, office worker Yuki has spent years with little interest in romance. After a man she meets at a drinking party insists she visit an unfamiliar, dangerous place, she goes along and encounters Kanadome, a man whose overwhelming presence catches her attention. Yuki is wary when Kanadome asks her on a date, but her long-dormant feelings begin to stir, and she accepts without knowing his hidden motive. Their meeting changes her life: she is drawn into an inescapable contract marriage with the formidable yakuza boss, beginning a love story between him and a reserved office worker.
