Onodera reflects upon how he imagined Christmas would be when he and Takano were together 10 years ago. Onodera runs a manuscript over to the printers and upon arriving back at the office, he receives an email from Takano telling him he can go home. As the elevator door opens, he sees Takano and Yokozawa talking and when the leave together, Yokozawa asks what Onodera’s plans are for the 24th, which happens to be Takano’s birthday. Yokozawa then implies to Onodera that he and Takano are still together, and he warns Onodera again to stay away from Takano. Onodera wishes Takano a happy birthday and as they part, Takano requests Onodera’s company on a drive for his birthday gift. On the drive, Onodera reflects on his feelings toward Takano, and Takano reveals the true nature of his relationship with Yokozawa and reminds Onodera that he has loved him for 10 years. They kiss, and Onodera admits to himself that he cannot resist Takano.
