Thank goodness! [He stands up, dusts himself off quickly, and then offers a hand to Yuuri to help him up. He laughs in embarrassment.] Haha, I'm okay; I'm used to falling all the time.
[He's still slightly pink, but trying his best to hide it.] Uhm, Yuuri? I know we couldn't find a costume when we went looking... but why did you decide to pick something... like this? [Then he smiles, having earlier sensed Yuuri's discomfort.] It looks good on you though, if you're worried about looking silly or anything...
