MARS Vol. 2 (Kodansha, 2019)

No one expected Kira and Rei's relationship to last. He's a street-wise biker with a dark past, she's a shy art student who's picked on by her peers. When another student steals Kira's painting and uses it to win an art show, Rei shows his love by socking the guy in the face. The meek Kira wonders if maybe they aren't made for each other after all.
