Intro

Today is the birthday of D.D.'s boss, Kou. Since they were too busy to celebrate last year, Sai and Guest had been talking for days about how they "wanted to do something that would really surprise Kou this year."

And this morning, Sai told Kou, "I want you to come to the conference room at 6:00 PM."

The conference room was decorated with balloons, presents, and accessories, mainly in black and white, to the point where it didn't look like the room where they usually held "meetings."

Current time: 5:54 PM

Sai looked at the clock hanging on the wall. "The Boss should be coming any minute now, don't you think?"

Creator Comment

If only I could go back to that day. This is the plot for the day before Kou dies, from "The Mad Dog Whose Master Died Wants to Die."
