Haunted by a dark trauma and hiding her true past, the enigmatic Fuyumi slips into the office of lawyer Sakisaka under the guise of a devoted secretary. Fuyumi, addicted to the rush of theft for a mysterious organization, infiltrates the office of lawyer Sakisaka. While he’s away on a business trip, she presses her hot, trembling palm against the cold steel of his safe, stealing a large sum of money from his safe and makes her escape. Sensing something dangerously volatile simmering beneath her cool facade, Sakisaka can’t tear his eyes from Fuyumi’s lithe silhouette as she moves through his office. Worried by her sudden shifts between seduction and tearful fragility, he turns to Yui, the detective who once loved Fuyumi, only to unearth secrets that will set their tangled hearts—and bodies—ablaze.
