Onodera leaves the office to visit the bookstore and thinks about how it has felt whenever Takano has touched him, but he dismisses these thoughts. At the bookstore, he runs into Yokozawa, and as they leave together, Yokozawa demands that Onodera move to a new home. Onodera argues that it his none of his business and teases Yokozawa that maybe he and Takano were dating. Yokozawa confirms this suspicion and Onodera realizes that Yokozawa doesn’t like him because he is protecting Takano. Back at the office, Onodera overhears a conversation between two women, one of whom saw Takano and Yokozawa together the night before. Takano invites Onodera to dinner, and though Onodera declines, Takano makes the plan anyway.

At dinner, Onodera becomes intoxicated and drunkenly confesses that Takano’s behavior has an emotional effect on him. The next morning, Onodera awakens to find himself naked in Takano’s bed, unable to remember the events of the previous night, but pain in his hips and back leads him to realize that he and Takano had had sex. Despite this obvious evidence, he openly denies this taking place.

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.

While trying to deal with the stress at work, Onodera gets an unexpected phone call and visit from his "fiancée" that causes a riff between him and Takano. On their way back home, Takano kissed Onodera in the train. When he is walking back home with Takano, Onodera saw his "fiancée" in front of his apartment. When Takano saw Onodera fiancé, he gets jealous and decides to go see his cat, Sorata, which is currently living at Yokozawa's house. Onodera stops him from going to Yokozawa's and explained everything about his "fiancée" situation to Takano. Onodera told his fiancée (early in the relationship) that he was in love with someone else (that person is Takano). Although Onodera didn't declare his love towards Takano, they kissed in front the door and Takano stayed for the night with Onodera, not going to Yokozawa's house.

He is also struggling with his feelings toward his assistant and longtime companion, Kaoru Asahina.

Tonight is the company's annual New Year's Party and Onodera has to learn how to navigate the crowd of publishers, editors, and authors. Onodera and the rest of the editorial party go to work early to finish up before the party when Onodera gets an unexpected call from his mother about An-chan. Takano, to Onodera, calls An-chan his 'girlfriend' until the end of the party where he thinks he might have learned the truth about Onodera's love.

Shouta Kisa and his perfect boyfriend Yukina haven't been able to see much of each other because of Kisa's work. Yukina always complies with Kisa when he says he is busy at work, which causes Kisa to believe that Yukina's lack of anger means he doesn't love Kisa as much as Kisa thought he did. Kisa finally resolves to make time for Yukina no matter what after he hears about the marriage of a friend of his when a major project was given to him from Takano. Again, Yukina says it is fine when Kisa can't make it, but Kisa goes to his work and waits for him anyways after hurrying to finish his work. There, he unexpectedly finds Yukina meeting with a girl and watches them as the two walk towards the naughty part of town Kisa knows all too well.

Kisa just wants to end things with Yukina but doesn’t know how to do it. At a moment of weakness Kisa agreed to go on date with a guy he met a while ago. But when he arrives, Yukina appears slapping Kisa and demanding answers. Kisa angrily tells Yukina that he saw him and a girl go to the hotel district, but Yukina informs him that she is only a friend who agreed to teach him how to cook certain dishes (so that he could cook for Kisa) in exchange for watching a movie. Kisa then tells Yukina that their relationship will still not work out because he does not even know anything about him, and Yukina replies by telling him things about himself such as his height, weight, blood type,shoe size,birthday,favorite foods, hobbies, his strengths and weaknesses and educational background, and that the person he loves is Kisa. Kisa then tries to say it still will not work because he has no self confidence, and then Yukina tells him to turn his love for Kisa into his confidence, ending the fight. Yukina then moves to Kisa's place for a week to make sure that Kisa will not come up with cazy notions and they will see each other more often.
