DASS-458 I am being eroded by a hidden desire that darkens my shadow. – Akane Mitani

Akane pays off her mother’s debts and acts devotedly. One day, at a job interview recommended by a friend, she meets a charismatic company president. Akane becomes his secretary and gradually comes to terms with his sadistic sexual desires, but… A man who can only get pleasure by hurting others, and a woman who sacrifices herself to avoid hurting others. When the desires and emotions of the two intertwine, Akane’s true self, which she herself did not know, gradually becomes apparent.
