Though he tries to explain away her claim, Kouta is soon reminded of his high school sweetheart when sees Kanou and realizes that the young girl is telling the truth. The two must now live together, but in a society where an otaku is thought of as a pervert and a freak, how is nine-year-old Kanou supposed to adjust to a new life with her father?

If you'd like a little more story with your otaku comedy, then you should give Otaku no Musume-san a shot. Like Doujin Work, it focuses on the lives of struggling amateur and professional manga artists.
OnM focuses more on developing its characters and plot than Doujin Work, but the results pay off in more rewarding laughs and some decent serious material. If you're looking for a manga with a similar tone, but a little more meat, Otaku no Musume-san is for you.
