I look up at him warily. I wish he'd slow down, it is hard for me to keep up with him. I think he tripped me over, and now he's pulled me up and has his hands on my shoulders. Or maybe he's holding me so that I don't fall again.

"I don't need a doctor, sempai. I only fell over," I point out, and then realise that he is a doctor. Was he making a joke? Is it rude that I didn't laugh? Too late now, I'll look like the guy that never gets the punchline in time.

I won't say no to sleep, though. There's only one problem, "how will I get to work tomorrow? I've got no clothes or toothbrush." I'm not going to show up in Date-san's clothes. We are not exactly the same size, and people will jump to conclusions if they think I stayed out overnight with him.
