Welcome to the N.H.K.

Tatsuhiro Satou, a university dropout entering his fourth year of unemployment. He leads a reclusive life as a hikikomori, ultimately coming to the bizarre conclusion that this happened due to some sort of conspiracy. One day just when his life seems entirely unchanging, he meets Misaki Nakahara, a mysterious girl who claims to be able to cure Tatsuhiro of his hikikomori ways. She presents him with a contract basically outlining that once a day they would meet in the evening in a local park where Misaki would lecture to Tatsuhiro in an effort to rid him of his lifestyle. During these outings, many subjects are discussed, though they almost always pertain in some way to psychology or psychoanalysis.
