Sekai Ichi Hatsukoi: The World's Greatest First Love

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.

As Onodera continues learning the ropes of manga editing and publishing, his interactions with Takano become more tense and uncomfortable. Takano eventually realizes who Onodera is, later revealing his identity to Onodera as his first love from high school, bringing back memories of being used and tossed aside, even though, as Takano explains, they were fuelled by a gross misunderstanding. He is left conflicted in regards to his true feelings toward Takano.

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.
