Asteroid in Love

When Mira Kinohata was younger, she met Ao at a local campsite. Together, they look up at the night sky, and Mira discovers that there is a star named after her but not Ao. The two then vowed to one day go asteroid hunting and locate a star to give his name to. A few years later, Mira decides to keep her promise and enrolls in the astronomy club at Hoshizaki High School. She discovers, however, that the earth science club will be created by combining the astronomy club and the geological research group. Mira reluctantly enters the club room, where she is reunited with Ao Manaka, who she promised to explore asteroids with, and is surprised to discover that she is a girl!
