Set in modern-day Japan. December 25th. "Christmas"โa day that everyone waits for, hates, anticipates, or feels sad about. For some, it might not be a day to look forward to, but for most, it is a day filled with happiness. And among those many people filled with happiness, there is a guy whose thoughts are impossible to read. "Ishigami Senku" He doesn't like Christmas. No, he doesn't like events in general to begin with. He calls them irrational. But this time, it was a bit unexpected. At 11 PM on Christmas Eve, he called his long-time childhood friend. Her name is Guest. You really can't tell what this guy is thinking.
