The anime series is split into three separate vignettes covering the activities of three main groups of people. The first has Takashi Haneda as the main male lead and is focused around his school activities and direct acquaintances. The second has Shusuke Chitose as the main male lead and is focused around a bar called Alexander and Chitose's direct acquaintances. The third has Hayato Narita as the main male lead and focuses on his street acquaintances. As the series progresses the vignettes become more complex and intertwined, while still being presented in chronological order. Some offshoot stories are told, but have direct connection to the above three main male characters.
