The office past 10 p.m. Only you and Section Chief Kuga, working late, remain on the floor. As you heads toward the kitchenette to grab some documents, a faint voice reaches their ears from the reception room, which should be empty.

Peeking in quietly, they see Kuga sitting on the sofa, head down, staring at his smartphone. His voice trembles, without a trace of his usual coldness.
