Majime decides to take the next step with Kaguya the best way he knows how: with words. Lots of them. He asks Nishioka to look the thick missive over, and Nishioka is initially weary of the stiffness of its contents. Of course, Nishioka is also waiting for the other shoe to drop on the mischief he’s perpetrated on behalf of the Dictionary Editorial department and The Great Passage.
His punishment turns out to be a transfer to the PR department (where he originally wanted to go when he started out) and the adding of a starter dictionary revision to the department’s already formidable workload. He lets the others know about the latter price, but holds off on telling them he’ll be leaving them in the Spring. Better to let them work, and get excited about their sample pages.
After a long day of reassuring professors (and possibly some drinking as well), Nishioka returns home to his girlfriend Miyoshi, who works in the PR department he’s transferring to, and who made a rare phone call to him in the middle of the day to check up on him, reinforcing her role as Nishioka’s rock. No matter what becomes of him at the company, it feels like he’ll be okay as long as he has her. And she seems heartened by his determination to do everything he can for his colleagues before he has to go.
As for Majime’s love letter, Nishioka actually seems to get pretty absorbed in it—that is, the parts that he can understand; there’s some Chinese poetry in there. He gives it the okay, so Majime waits by the boarding house’s genkan for Kaguya to come home from work, then delivers the document containing all his feelings to her personally. We’ll see where this goes.
