Sekai Ichi Hatsukoi - The World's Greatest First Love

Ritsu Onodera hated the fact that people claimed he only got into his father's company because he was the son and promptly quits. He starts his new job at Marukawa Publishing house but ends up in a department for shojo manga, something he's neither interested nor experienced in. To make matters worse, the first impression he gets from the high handed editor in chief Masamune Takano is terrible...

Ending up in the shoujo manga department at Marukawa Publishing was the last thing Ritsu Onodera expected when he left his father’s company. Worse yet, his first impression of the department and the editor-in-chief have him ready to run out the door!

Ritsu Onodera is a total rookie when it comes to editing manga. When a deadline is looming, he is forced to go to an author’s house and learns how scary editor-in-chief Masamune Takano can really be. Can he survive this job, or does more trouble await?

Onodera is reeling after finding out Takano’s identity. How can he work with the man who hurt him so? Between his mixed up feelings and his new work piling up, Onodera also has to handle a new face that is less than friendly and…really close with Takano?!
