The kiss may be light and brief, but that doesn't seem to bother Inigo. He smiles all the same when he pulls his head back a little, but it's exactly when he's looking at Yuki that he seems to realise something is up. Sure, the other is smiling, but it somehow feels like there's something awkward here. Inigo can't quite place it though - and it makes him wonder if maybe it's something about him. Did he say or do something wrong? Either of those two options happens so often that he's quick to assume that must be it.

But if that's the case, he has no idea what he did wrong. And Yuki's hands are still on his collar like that too...

".. Yuki?" Concern creeps into his voice. "Hey, what's wrong? Tell me."

Maybe it's nothing. Maybe he's just reading too deep into things, or maybe the worry about the whole swimming deal is just making him more paranoid than usually. But he has to ask, just in case. He can't let his boyfriend deal by himself with anything worth worrying about, after all.
