(from ebookjapan):

This is the story of Julie, a young woman who aspires to be a SF novelist but can't even make it through the day. Nothing much is going on, and life is not particularly interesting.

This is Dinosaur Manor, a nondescript apartment building where someone from around the place is living. Modeled on Leiji Matsumoto's personal experiences, this is a human drama in a single four-and-a-half-tatami-mat room.
