Two years after a painful rejection, Junichi Tachibana has retreated into a closet-sized planetarium he built for himself, avoiding much of the social side of high school. This manga adaptation of the Amagami dating sim follows his halting reconnections with classmates Tsukasa Ayatsuji and Kaoru Tanamachi across separate story arcs, with friend Masayoshi Umehara and sister Miya Tachibana rounding out his circle. Each arc gives a different heroine room to slowly draw Junichi back out.
