Starry Sky - S01

Seigetsu Academy used to be an all-boys school, but it is now co-ed and focuses on teaching its students about astronomy. Tsukiko Yahisa enrolls as the first and only female student there. At her side are her childhood best friends, Kanata Nanami and Suzuya Touzuki, who protect her from the attention of the rest of the student body. As Tsukiko gets used to her new surroundings, she meets 13 different boys, each based on a Western zodiac sign. Over time, her connection to these boys pulls her into star-crossed paths that draw her into many complicated relationships.
