Natsuo had spent the last thirteen days in a square room with a stained futon and tatami mats. The only window was a tiny slit in the wall that let in a sliver of light from the sun.

The first few days after he was detained for Suzu's murder case, he was intensely questioned by the female detective named Saika Ishikawa, who arrested him in the first place. A duty lawyer and a prosecutor also visited him, but he wasn't allowed to make phone calls or have visitors.

He would spend hours just lying on the futon, letting his mind wander and drift in the silence.
