Eizouken ni wa Te wo Dasu na!
|
Genshiken is about an anime-manga-viewers university club, and Eizouken is the-making-of-Daicon-III but setted in a school club. I think they are similar beacuse both series have the otaku essence and a lot of references to many anime, movies and people who work in this industry.

Tsukiatte Agetemo Ii kana

Both series portray adult romance in a bittersweet tone, but optimistic and sometimes (very) funny. And these two add subtly the presence of family, friends and many social dynamics. Personally I like more Harukaze no Etranger because of the complex relationships, but Tsukiatte Agetemo (...) explores the dynamics and insecurities when a couple is established

Brigadoon: Marin to Melan

Both series employ a similar humor (and include fanservice) at the beginning of they chapters. Subsequently they reveal a melancolic background. If I make a comparison, Brigadoon is better than Abenobashi, although both are highly recommended.
