The lively Narumi Momose is running late for her first day of work at a new office after sleeping through all four of her alarms. As she rushes to catch her train, she vows to herself that none of her coworkers will discover her terrible secret: she is an otaku and a fujoshi. Her plan, however, is thwarted when she runs across Hirotaka Nifuji, an old middle school acquaintance. Although she attempts to preserve her secret by inviting him out for drinks after work, her cover is blown when he casually inquires about her attendance at the forthcoming Summer Comiket. Fortunately for her, the sole witnesses—Hanako Koyanagi and Tarou Kabakura—are also otaku.
