[He's been looking around for Keith for a while now since. well. if they were clingy with each other before... now it's ridiculous. It's been approximately Too Long since Keith and Shiro were next to each other so obviously that's weird.
And also he was hoping to buy some more warmer clothes but... well. He had no konpeito before and now he only has dark konpeito thanks to clone shenanigans. So he wasn't able to get much in the end.
Of course, he spots him instantly even if slightly hiding and the sky darkening and-- well. he does a double-take immediately.]
