Basically a bunch of people who have like zero ability to make friends gets together and join a club about making friends. There's a guy that tends to scare people away, a girl that has an imaginary friend, a girl that has followers but no friends, a 10 year old nun, a science geek who is VERY perverted and a guy who wants to be manly because his family is from a long line of samurai. His only problem is that he's too cute. I mean, they have him dress up in a maid outfit for the entire series! Oh! And the first guy's little sister who is always dressed in cos play.
But it's about their lives and you end up learning a few things about a few of the characters. Primarily the first three people I mentioned.
