Sasori to Otome

Saotome is an established author that hasn't published anything in so long that his fans think he's deceased. The reason for his long break is because he's determined that his upcoming release contain a scene where the protagonist tells the object of her affection her feelings...and he just can't bring himself to write it. Enter Sasasori, Saotome's new editor and former high school friend. Sasasori knows Saotome has it in him to include some romance in his stories, since back in the day, he himself was the object of Saotome's affections!
