Girlfriend (Kari)

+ a bunch of cute middle school (I think?) girls + lots of blushing + the somewhat exaggerated cutesy voice + main girls are brunette and have almost the same personality + main girls have some stage fright + have a blond foreign girl who is eccentric and outgoing + moe + no male characters 

The story follows a girl and growing their circle of friends as they support each other through the various trials and situations that comprise high school life. -If you are looking for a all moe situated anime -if you want to pass time recreationally -You want to live life the fullest 

Slice of Life-Moe shows that have cute girls doing cute things, with character prototypes that are somewhat similar to each other. Both shows have also slight resemblance through the light fanservice and semi-shoujo ai atmosphere.  

Both shows are slice of life about cute girls doing cute things, but Girlfriend (Kari) focuses more on school activities. 

Both are diabetes-inducingly cute shows with cute girls doing cute things. Both shows feature an almost entirely female cast and have a blonde European exchange student who is interested in Japanese culture. 

The two anime (KH Series) and GF Beta are based on Game. No male MC on anime. Male MC on both mangas. A lot of girls. Yuri subtexts.
