Haruki joins Mozasu’s class at school at age 11, and he’s ostracized because of his home life—a disabled brother and an abandoned single mother—and the inaccurate rumor that he’s a burakumin. Mozasu is drawn to his fellow outcast, and they become best friends. Haruki is romantically attracted to Mozasu and other men, but he never reveals this, though his wife, Ayame, once sees him having sex with another man in a park. Haruki and Ayame take in Haruki’s brother, Daisuke, after his mother’s death. Haruki studies at the police academy and becomes a highly ranked detective in Yokohama. He has a lifelong bond with Mozasu’s son, Solomon.
