Kyouhei was easily surprised, yes, but he was also good at reacting quickly to unexpected situations. It was part of his military training - when something happened, you had to move.
He didn’t think that his training was meant for the day he saw someone trip so hard he nearly flung themselves, face first, onto the floor so that Kyouhei could react just in time - catching his shoulders so that he didn’t hit the ground so hard he broke their nose - that was just a bonus.
The collected moment didn’t last long, though, because he recognized this person and the shock nearly made the biochemistry student drop him, mostly out of surprise.

“Hey, aren’t you the person who spied on me that one time!?” He blurted out, still as a rock, waiting for the stranger to recover. “You thought it was strange I could sing? Wasn’t that you?”
