The World's Greatest First Love

Onodera wakes up in the doorway, still holding on to a convenience store-bought dinner, and suddenly remembers a meeting that he was to sit in in the morning. On the subway, he complains about his lifestyle after joining the shōjo manga department. Onodera is surprised by the hostility shown in the proposal meeting and dreads future meetings. After the conference, Onodera meets Sumi Ryouichi (father of Sumi Keiichi from Junjo Romantica), whom he was in charge of before in the literature department at his father's company. Through Sumi sensei, Onodera also meets Hasegawa of the literature department, who later dropped in on Onodera during work and invited him out for a drink. Takano, who happened to hear the invitation, rejected it for Onodera. After commenting on Takano's strictness, Hasegawa reminds Onodera that he can always transfer to the literature department if he no longer wants to work on manga. Later, Onodera encounters Takano at the library and tries to run away. Takano saves him from falling down the stairs as Onodera trips on fallen leaves; as they embrace on the stairs, Takano tries to evoke past memories from the time when they were dating in high school, but Onodera escapes again. At the apartment, Onodera encounters Yokozawa, who apparently was coming out from Takano's room with Takano's cat, Sorata. Yokozawa confronts Onodera and claims Takano as his, and further throws Onodera into confusion by recounting how Onodera had only hurt Takano since they have known each other.

Kisa freaks out and cannot concentrate on his work because of his constant flashback to the scene with Yukina at the cafe. He soon receives an e-mail from Yukina inviting him to the bookstore to see the book promotion display stand that they planned earlier. This reminds Kisa of the kiss and he throws himself into a brief depression after convincing himself that Yukina cannot be serious about the kiss. He gets even more down after belittling himself career-wise by comparing his achievements to Takano's. After work, Kisa subconsciously arrives at the bookstore, where Yukina shows him the display stand and tells him that the reason he worked so hard on the display was because of Kisa. Noticng that Kisa has been trying to avoid him, Yukina invites him to talk after he finishes work. As Kisa waits for Yukina outside the store, he encounters the persistent ex-lover yet again. The ex-lover finds out about Kisa's feelings for Yukina and threatens to expose him but was defeated by Yukina, who appeared suddenly and claimed himself to be Kisa's boyfriend. Kisa and Yukina end up in Yukina's house, where Yukina finds out that Kisa was in charge of editing all his favorite manga. He then surprises Kisa by telling him how he knows about Kisa's feelings for him from the start, but when he begins to talk about the kiss Kisa immediately interrupts him by saying that he does not care, which triggers an unexpected response from Yukina, who confessed his love for Kisa. Afterwards, Kisa receives notice that his book is getting a second printing, and when Yukina tells him that he loves him after Kisa notified Yukina of the news, Kisa decides that he has fallen in love despite the fact that he claims he can only like men's faces.

The episode begins with Ritsu having another flashback dream, in which he sees Saga sleeping in the library and tries to find out what book he was reading, but runs away when he thinks Saga is about to wake up. Afterwards, Ritsu wakes up and goes to work. At Marukawa, Ritsu's assignment is to make his first proposal as a manga editor to publish the manga he's supervising as a book. It is initially rejected by Takano, so he stays late at night working on it. Later that night, Takano helps Ritsu with his proposal, even though Ritsu didn't want his help. After a while, Takano suddenly kisses him to break the tension, and consequently gets hit by Ritsu. Yokozawa then arrives and sends Takano to meet someone. When he's alone with Ritsu, Yokozawa proclaims Takano as his property, and doesn't believe Ritsu's words about not having any relation with Masamune other than that of boss-subordinate. At a bookstore the next day, Ritsu meets an old female friend from his previous job, and they go for drinks. She gets drunk, stumbles, and falls into Ritsu's arms. This is seen by Takano, who had just arrived with Ichinose Erika, a female writer, to discuss work (Ritsu misunderstands this and feels jealous). When he arrives home, Takano accuses him of not working hard enough. Takano makes another pass and admits to being in love with him, but Ritsu (who is still wary of admitting his love for Takano) runs away and leaves Takano alone in his apartment. The proposal meeting day arrives and Ritsu is quite nervous, but Takano tries to cheer him up on the way to the meeting. In this episode another Junjou Romantica character appears; Isaka Ryuichiro.

This episode introduces a new set of characters - Chiaki Yoshino, a male author who releases shōjo manga under the female pseudonym Chiharu Yoshikawa; Yoshiyuki Hatori, his manager and childhood friend; and Yuu Yanase, his chief assistant, who is on rough but unclear terms with his manager. Hatori's increasing coldness toward Chiaki begins to take its toll on their friendship, and when pressed on personal matters, Hatori becomes distant. Chiaki later sees Hatori and Yuu in an alley having what he interprets as an argument between lovers. Growing distraught with confusion that begins to affect his ability to write, Chiaki slowly realizes his feelings for Hatori. However, Hatori later confesses his love for Chiaki, much to his surprise, along with admitting that he had changed Chiaki's management behind Chiaki's back, fearing that his confession would put their relationship on bad terms. This forces Chiaki to admit his own budding feelings.

After Takano and another staff member have a heated argument in the Emerald office about an underprinted publication, Onodera sees the two of them later having a seemingly friendly conversation in the lobby, stirring a sense of jealousy within him. Perturbed by the fact that this bothered him, he begins avoiding Takano even more, prompting Takano to confront him about the situation before it begins affecting their capacity to work together.

Onodera begins work at his new position at Emerald, and is harshly introduced to their production "cycle" by being thrown into the mess of their burned-out phase, in which everyone appears brutally overworked and exhausted. He is shocked to find them transformed the next day into composed and energetic people who spiritedly show him the basics of manga editing.
