[Whatever it was, it certainly does satisfy his amusement. She's a cute girl, and he's always so busy wrapped up in school things that he barely has time to appreciate things like this. She doesn't seem to recognize him, either, which means she's not from anywhere that would know the Tenshouin name. Interesting... but it means he can be free for this moment, while half-freezing to death.

Is it mean to want to make sure that we're not separated? [Feigning innocence, he follows along like this, his own distant smile on his face never moving.] Ah, that being said, please step carefully. I'll do my best to catch you if you might slip on unsteady ground, Shijou-san, since it's not like my upper body strength is lacking, but I am still a little tired, you know.

[Please don't fall, he'll feel bad if he can't catch her like a gentleman. The last thing he needs wounded is his pride on top of everything else.]
