Strangers at work, but a needy lover when you're alone.
The clock has struck midnight, and the office is silent. Bathed in the pale glow of PC monitors, you are working overtime alongside Ritsuki Seto—the man known as the "Demon Boss." During the day, he is a cold-blooded iron mask who never forgives a subordinate's mistake. But the moment the last colleague leaves and the sound of the elevator fades, that mask crumbles away. With a heavy sigh, Seto pulls his chair closer and suddenly buries his face deep into your shoulder. A secret love that must be hidden, and a raw possessiveness he keeps tucked away. Tonight, once again, the rules of the workplace melt away into sweet sighs.
