 Sakuya Shiina is the president of a star-gazing club at her high school. On her eighteenth birthday, she receives a pink dress from Chihiro, a handsome and mysterious boy around her age who suddenly appears at her birthday party. She initially believes that Chihiro is a friend of Kanade, her guardian, but she later learns that Kanade had invited him to the party thinking that he was her boyfriend. Kanade then becomes offended for being deceived, but Sakuya becomes even more intrigued by Chihiro. She finally gets her chance to meet Chihiro again, and during a discussion about the stars (in which Sakuya says that the star Alphard, the brightest star in the constellation Hydra, is her favorite), Chihiro suddenly exclaims that he hates Sakuya and disappears once again. Sakuya becomes even more troubled when, a few days later, Chihiro suddenly enrolls at her school and becomes a classmate. As the story goes on, Sakuya's feelings towards Chihiro grows, and Chihiro starts warming up to her.
 Twinkle Stars was written and illustrated by Natsuki Takaya. It was serialized by Hakusensha in the shōjo (aimed at teenage girls) manga magazine Hana to Yume from 5 June 2007 to 20 January 2011.

 In his review of the series for Otaku USA, Che Gilson praised Twinkle Stars as a "solid shojo romantic drama" with "charming girls, cute guys, a good sense of pacing, and pathos." He further praised Takaya's ability to portray her characters' "inner and outer emotional states with art." However, he noted that Twinkle Stars contains "many of the same elements" as Takaya's previous series, Fruits Basket, including "a frustrating penchant for passive heroines."
