Cage of Revenge [Spunk!]

Synopsis

Tsuyoshi is an ordinary office worker at a company. His colleague Eiko looks down on him, Miki undermines his work, and his boss Goki scolds him—his days are utterly unremarkable. One day, a doctor tells Tsuyoshi he has only six months to live. Learning of his limited time, Tsuyoshi confesses to Saki from the neighboring department, only to be rejected and driven to despair. Just when all seems lost, fortune smiles upon him—he wins the lottery. With more money than he could spend in six months, Tsuyoshi decides to rent an isolated mountain villa as the stage for his revenge against the women who have mocked him all these years.
