However, after losing her only family—her mother—one year ago, she begins working at a no-pant cafe to repay the debts left behind. One day, Koji, a ruthless loan collector, arrives at the shop, claiming overdue interest payments, and ends up raping Rumiko. Unexpectedly, she falls in love with her attacker, Koji. Directed by Akiko Kirishima, this third installment blends nostalgic Showa-era romance with a lewd, emotional narrative filled with laughter and tears. A grand tale intertwining thrilling romance and harsh reality—seemingly impossible, yet profoundly believable.
