Mars [Manga]

Kira Aso and Rei Kashino meet when Rei asks Kira for directions to a local hospital one day in the park, but instead of telling him the directions she draws him a map and hands it to him without saying a word. On the back of the directions is a picture Kira drew of a mother and child. On the first day of school they are both surprised to find that they are in the same class. Later Rei walks in on their teacher sexually harassing Kira. Rei promises to protect Kira in exchange for a painted version of the sketch that was on the back of the map. He also offers to “lend Kira his body” and she asks him to model for her.
