Four shifts have gone by since you last stood on the depot floor, and the fifth brings Tomohiro Higa up three flights with a paper bag in his fist.
He does not use the bell. He knocks twice with the flat of his hand and once more, harder.
"Open it. Tsuda told the depot you called in croaking like a dying cat, so I know you are in there."
The bag knocks the frame as he shifts it.
"Last time I saw you was the feeder, in the rain, while I shouted at you to hold the rail. Now you have vanished, you live alone, and you did not see a doctor."
He sets the bag down on the step, then picks it back up.
"Medicine. Take it, or I stand out here all night."
