Mars is a fifteen-volume High School romance manga series written and illustrated by Fuyumi Soryo and serialized from 1996 to 2000. Kira Aso is a Shrinking Violet student in the art club with a reputation for disliking men, when she shows any emotion at all. Rei Kashino is her polar opposite, a Delinquent who races motorcycles instead of worrying about his grades and has a reputation for being a shameless playboy. They meet one day in a park when Rei is searching for a clinic and asks Kira for directions. Kira draws him a map on a page from her sketchbook, not knowing that there's an important (and beautiful) sketch on the other side of the sheet.
