In an interview with , Matsumoto stated that although she felt the premise of Unexpected Naughty Fukami was cliché and conventional, the editorial department had suggested it as an idea when she had shared with them that she enjoyed cliché and conventional stories. While drawing the manga, she paid attention to the timing and expressions so that the story would be easy to read. The bed scene in the first episode was the first time Matsumoto had drawn a "love scene." For volume 2, Matsumoto considered having Kaji and Fukami become a couple early on in the story, but she changed some parts because she thought "it would take more time and effort [for Kaji] to become closer to Fukami."
