This is a short, about two-and-a-half-second anime vocal clip in which Arisa Ichigaya stammers out a flustered string of awawa sounds followed by a hurried plea to wait a moment. It feels frantic, embarrassed and oddly cute, like someone caught completely off guard and trying to buy time. It comes from the song 'Su, Suki Nanka Janai!' performed by Arisa Ichigaya.
