Shy 16-year-old Kira Asou would rather draw in solitude than draw attention to herself. At a park, she is approached by her classmate Rei Kashino—known for being a womanizer—who asks for directions. Skeptical of Rei's motives, Kira quickly draws a map for him in chalk and flees. Unbeknownst to her, Rei discovers one of her sketches on the back of the map and is captivated by her artistic talent. To Kira's annoyance, Rei immediately recognizes her at school, but she ignores his attempts to start a conversation. However, Rei's sincere compliments on her drawing lead Kira to view the violent rebel in a more favorable light. After watching him kiss a statue of the god Mars, Kira is so moved that she instantly asks him to model for her. As Kira and Rei's chance encounter begins to blossom into a thriving relationship, what will become of these two opposite personalities?
