__Occupation:__ editor of literature (former), editor of shoujo manga (current)

Ritsu is a 25-year-old jaded literary editor. He is the only son of the head of Onodera Publication and previously worked at his father's company in the literature department. Hearing his fellow co-workers accusing him of taking hand-outs from his father, he decides to show that he can be successful on his own by going to work at Marukawa Publishing. After being hurt by his first love in high school (when he was 15), Ritsu vowed to never fall in love again. His resolve is tested, however; when he is reunited with the boy he once loved: now very much a man and his new boss! It was also mentioned that he was one of Usami Akihiko's (from Junjou Romantica) editors at his previous job.

He has light brown hair and long bangs that frame the sides of his face. He has wide, green eyes and fair skin. He is described by Yoshino as being very attractive and having a "vogue body type", with high hips and a small face with perfect features.

Onodera Ritsu has just transferred from his father's publishing company to Marukawa Shoten. Assigned to the shoujo manga division, he crosses path with the person he'd least expected to meet. Takano Masamune is the editor-in-chief of the division Ritsu's been assigned to, and the two seem get off on the wrong foot right from the very start when Takano unexpectedly kisses him. However, there is more to than what meets the eye: Takano is actually Saga, Ritsu's senpai and high school love, whom Ritsu had thought to have played him for a fool by taking his affections for granted when he confessed and summarily dumped him.

Two OVA episodes featuring additional stories. 
Episode 0: Ritsu and Takano used to date back in high school, but broke up due to a misunderstanding. This is that story.
