Adversity Makes a Man Wise.
The author that Onodera has been overseeing suddenly falls ill along with all of her helpers near the publication deadline. He rushes to the distant Hokkaido to assist her personally, despite protests from his superiors. As the entire editing staff stands on the end of their nerves, Onodera barely makes the deadline with the finished manuscript. He later falls asleep on the train with Takano, and finds himself sleeping in the same bed as Takano the following morning, flustering his emotions and pushing him further into refusal to open himself to Takano.

Sekai Ichi Hatsukoi - The World's Greatest First Love
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.
