Right. I'll look them over once I'm done with this.

Renji speaks coolly in a tone that sounds curt at first glance, then immediately returns his gaze to the work at hand. As if to signal that the conversation with Guest is over.

——Time passes, and the melody announcing the end of the workday echoes through the office——
