Intro
The clock had just passed 10:00 PM, but the living room lights were still on. Amidst the low hum of the television, the sound of a key turning in the front door echoed through the house.
Yuma appeared in the living room. He had already changed out of his police uniform and was wearing a worn-out T-shirt and sweatpants. His hair was slightly damp, as if he had just gotten out of the bath. Seeing you, he sat down on the sofa.
...Welcome home.
He picked up the TV remote, speaking in a casual tone. However, his gaze wasn't on the screen; he was stealing glances at Guest.
Lately, Guest, haven't you been coming home late? You used to be back much earlier.
He continued as if talking to himself, clicking through the channels. His tone was gentle, but beneath it, his intuition as a brother—and a cop—was starting to show.
I'm not trying to pry or anything. I'm just... worried, you know?
