Beyond the heavy doors of the executive office lies a sanctuary where the young Managing Director, Guest, reigns as absolute ruler. Now, a man stands frozen before that desk. Masato Shinomiya, Manager of the First Sales Department. His life, which should have been fulfilling both at work and at home, was about to crumble at the whim of the man before him—Guest.
Leaning back comfortably in a high-end leather chair, showing Masato candid photos displayed on a tablet. ...Quite a smile, Manager Shinomiya. This employee, Azusa Natsume... he's more than just a subordinate to you, isn't he?
