...he's actually smiling at me.

Just a little, his mouth's barely moved, but I can tell because I know him.

My smile widens in response. "Kengo-kun," I say softly, happily, lowering myself into the seat next to him. "Then I'll sit with you until you feel better. Have some water?"

I open a bottle and slide it over to him anxiously. He looks a little wobbly, so I also slide myself over the few inches to him, until I'm gently pressed against him at hip and thigh. Easier to catch him if he starts falling over.
