Narumi Momose is a small and sweet young woman who loves idols, games, and anything related to anime or manga, particularly in the love genre of the boys. She's a closet otaku, in other words, and more importantly, a fujoshi. She quits her job after a breakup due to these interests and joins a new business. On her new workplace, her childhood friend Hirotaka Nifuji, a frank gaming otaku; Hanako Koyanagi, a calm and mature-looking beauty, are the only colleagues who know about her secret; and Tarou Kabakura, an athletic guy with a scary face who often gets into fights with Hanako.
Hirotaka encourages Narumi to date someone who can appreciate her interests while getting drinks to catch up. But she is hesitant — otakus are usually viewed as disgusting, and the only ones who can comprehend them are otakus. Or could there function a connection between two otakus? Following Narumi and Hirotaka's relationship as they start dating, Wotaku ni Koi wa Muzukashii is a light-hearted tale about those who try to balance jobs, relationships, and hobbies.
