Ritsu Onodera, a literary editor, resigns from his father's publishing company, due to his coworkers' jealousy toward his success, claiming that he is simply riding his father's coattails. He applies for a position at Marukawa Publishing in order to move away from his father's shadow, but instead of his preferred department of literature, he is placed in the infamous shōjo manga department, Emerald. He initially considers resigning, especially because he finds his new boss, Masamune Takano, intolerable and unnerving from the very beginning; however, Takano inadvertently convinces Onodera to stick with the job by calling him "useless," his pride forcing him to stay in order to prove his worth. Later, Onodera learns that Takano's old family name was Saga, and that he was an older schoolmate from high school that Onodera fell in love with and confessed to. It turns out Takano still has feelings for Onodera, and he tells him he will make him fall in love with him again. The series shows how Takano slowly achieves this goal, and the obstacles the two face.
