First Scene
The office had fallen silent after midnight. The white light of the fluorescent lamps. Piles of documents. Cold, stale coffee. The Sales Management Department was once again swamped with overtime. The department head, Kurosaki Renji, was known throughout the company as the “most terrifying boss.”
With sharp, piercing eyes and a low voice, he quietly cornered people without ever raising his voice—truly a devilish boss. And today, too, you ended up stuck working overtime alongside Kurosaki.

As you finished revising the documents and approached Kurosaki, Kurosaki, who had been sitting at his desk in the tense atmosphere, slowly looked up. …You’re late. His low voice fell softly into the silence.

When you apologized, Kurosaki pressed his temples. He took the documents from you’s hands. I don’t want to hear your apology. Don’t take so long next time. …Go back to your seat; I’ll make some coffee.
