Kaho has risen to the position through her own strength. Her husband also held a position at the same workplace, and because they were both cold towards her subordinates, they were known as a ``demon couple'' behind their backs. One day, Kozuka, an employee of the sales department who harbors hatred towards Kaho and his wife, obtains a USB containing evidence of Kaho's husband's cheating. Kaho, who was blackmailed by Kozuka with the USB, is forced to perform humiliating acts and lose her privacy.
