Unexpectedly Naughty Fukami (Manga)
SYNOPSIS
Unexpectedly Naughty Fukami (Japanese: やたらヤラしい深見くん, Hepburn: Yatara Yarashii Fukami-kun) is an ongoing Japanese BL workplace romantic comedy built on a very simple mismatch. Kaji Akihiro is the sales department's ace, admired across the office for his looks, his charm and the ease with which he handles clients. Privately he is a self-absorbed playboy who silently rates his coworkers on a numerical attractiveness scale, and almost nobody clears the bar. Yu Fukami, the outwardly plain, frumpily dressed colleague from the IT department, barely registers on that scale at all, until an overnight business trip forces the two of them to share a room and an unexpected encounter shows Kaji that the drab exterior has been doing a great deal of work.
What follows is less a seduction than a standoff. Kaji Akihiro is a man convinced he already knows exactly what he wants and how quickly he can have it, and the discovery that Yu Fukami is far more striking than his daytime appearance suggests only sharpens the appetite. Yu Fukami, for his part, is guarded in a way that has little to do with shyness; he keeps his distance deliberately, and the unremarkable clothes turn out to be a decision rather than an accident. Back in the office the two must go on working together as though nothing has changed, with colleagues, client dinners and department politics pressing in around a slow burn neither man will name out loud. The comedy comes from Kaji's certainty. The weight comes from how long it takes him to notice that certainty is not the same as understanding.
Ayaka Matsumoto writes and illustrates the series, which has been serialized digitally on ComicFesta under the Screamo label since December 7, 2022 and collected by Suiseisha into bound volumes, four as of early 2026. Its mix of office farce and real emotional vulnerability carried it well beyond its original serialization: a short-form anime from Studio Hōkiboshi followed in 2025, then a live-action drama directed by Emiko Shirai in 2026, an unusually fast adaptation pace for an ongoing digital BL title. Mature themes are part of the register, but the story's centre of gravity stays on the workplace and the negotiation between the two men. English readers can find it digitally through Coolmic, with Seven Seas Entertainment issuing an official print edition under its Boys' Love imprint from September 29, 2026. The manga remains the fullest version of the story, still adding chapters past where either screen adaptation stops.
