Sekaiichi Hatsukoi EP4 - 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.
