Chara snorts at the bleh, a thick noise in the back of their sinuses, and clamps a hand over their nose at the undignified of it (not that this really is describable as dignified to start with but shhh).

That feeling in their chest is getting stronger and hotter, and they don't know what to do with it, other than that they suddenly burn with an itch to do something to keep this going, like spinning a top to keep it from falling down.

They reach over, and press their finger down on one of the piano keys, feeling slightly giddy and slightly not here at all.
